of the product may be modified or converted. The safety instructions are

to be followed without fail.

PSP SERIES USER MANUAL

2. Safety Information

Note: Damage caused by failure to observe the operating

instructions voids the guarantee.

We accept no liability for consequential damage and accept no responsibility

for damage to property or injury to persons caused by improper operation

or failure to observe the safety instructions. Such cases void the guarantee.

a) Installation and handling safety instructions

Observe the following rules when installing the instrument:

a1. Avoid use the instrument in extremely cold or hot locations or

directly adjacent to a heating fan.

a2. Never switch the instrument on immediately when it is brought

from a cold environment into a warm room until the instrument

comes to room temperature as under the adverse conditions, the

resultant condensation may destroy the instrument.

a3. Ensure there is proper ventilation for the vents in the case (front left

side and cooling fan on the rear) to prevent heat build-up from

damaging the instrument.

a4. Never operate the instrument near hot soldering irons.

a5. Do not place the Power Supply with its front panel down to avoid

damaging the operating controls.

b) General safety requirements

The Switching Power Supply PSP series has been fully inspected and

tested with technically safe condition before shipping from the factory.

To maintain this condition and to ensure safe operation, it is essential

for the user to observe the safety instructions and warning notes which

PSP SERIES USER MANUAL

are contained in this user manual.

The instrument is constructed to Protection Class I. It is equipped with

a VDE-approved power supply with safety cable and may only be used

with and connected to AC supplies with safety earthing.

Ensure that the (yellow/green) earthed wire in the instrument, in its

power cable and in the AC supply remains sound, because a damaged

earth wire can endanger life.

In commercial facilities the accident-prevention regulations of the

industrial employers' liability association for electrical systems and

equipment must be observed.

In schools, training facilities, hobby and self-help workshops, the

operation of power supplies and accessories must be supervised by the

trained personnel.

Make sure that only the fuses of the given types and nominal current

ratings are used as replacements. The use of repaired fuses or the

bridging of fuse holders is not permitted. A small flat-bladed

screwdriver is required to change the AC fuse. Carefully lever up the

cover in the AC power socket and withdraw it. Remove the defective

fuse and replace it with an intact one of the same type and nominal

current rating. Afterwards replace the fuse cover.

The measuring instrument is operated only when the case is securely

closed and screwed up.

PSP SERIES USER MANUAL

While proceeding the operation of power supplies, the wearing of

metal or other conducting jewelry such as chains, bracelets, rings, etc.

is not recommended.

Note: Power supplies are not intended for use with/on

people or animals.

When connecting the outputs of more than one power supply in series

voltages may danger to life (> 35 VDC). Only power supplies with an

identical output (current and voltage) specification may be placed in

series or in parallel, otherwise the weaker of the two will be damaged.

The instrument is to be placed onto a hard, non-inflammable base, so

that cooling air can enter unhindered. The cooling of the unit occurs

predominantly through convection.

Note: Power supply ventilation holes should not be

covered.

Power supplies and their connected loads should not be left operating

unsupervised. There are measures for the protection and safety of

connected loads in the face of power supply incidents (e.g.

overvoltages, complete failure) and effects and dangers stemming

from the loads themselves (e.g. unduly-high current consumption).

Faulty power supplies can produce voltages over 50 V DC, which can

be dangerous even when the indicated normal output voltages of the

units are lower than this.

Note: For power-on work, only tools expressly intended

for this should be used.

PSP SERIES USER MANUAL

The power supply outputs and connecting leads, sockets and terminals

must be protected from being touched directly. In addition, the leads

used must be sufficiently insulated and voltage-proof and the contact

points safe from being touched (safety sockets).

Use of bare metal leads and contacts should be avoided. All such items

are to be covered by suitable, nonflammable insulating material or

other measures taken and therefore protected from being touched

directly. The electrically conducting parts of the connected load must

also be appropriately protected from being touched directly.

If the instrument is assumed that safe operation is no longer possible

according to the following phenomena, then the unit must be switched

off and protected against unintentional operation:

- the unit shows visible signs of damage,

- the unit no longer functions and

- after prolonged storage under unfavourable conditions or

- after severe transportation stress.

Do switch on the switched power supply immediately when it has been

brought from a cold environment into a warm room until it comes to

room temperature as under adverse conditions, the resultant

condensation can destroy the unit.

5. Functional Description of Operating Elements

With its continuously adjustable voltage and current settings, this

power supply can be used universally in school, work, hobby, and other

applications. An electronic current limiter protects the power supply from

overload and short-circuits at its output; a fan controlled by a temperature

circuit protects the power supply (its electronics) from thermal overload.

During such an overload (short circuit or overload) the output is

regulated down, i.e. the voltage is reduced. Only when the short-circuit

has been remedied is the output released.

The set values can be read via the illuminated multiple-line LCD

display. The voltage, current or power setting is adjusted by means of an

encoder wheel in 10mV, 20mV, 1mA, 2mA, 10mA and 1 W steps

respectively. Therefore the exact adjustment of the output voltage and the

current limit and maximum output power is possible. However, observe

the safety hints without fail.

PSP SERIES USER MANUAL

6. Operating Instructions with keypad input

A)Basic setting

a) Connect the AC power cable to the AC power socket and ensure

that it is firmly seated. Then plug the earthed power plug into an

earthed AC power socket.

Attention: The continuity of the safety earth wire must be

unbroken within the instrument, within the AC power

cable and within the AC power socket otherwise life will

be endangered.

b) Press the AC power On/Off switch

Attention: The earth connector in the front of the

instrument and the RS-232 interface connector earth are

connected directly with the earthing wire of the AC power

input socket and of the connected AC power socket.

Before operating the instrument each time, first check and

ensure that the 4 mm sockets of the instrument is well fit of

no damage.

B) Setting the limits

The voltage, current and power output values are each limited to a

maximum. This upper limit can be varied downwards. Setting the limits

is carried out using the “V LIMIT” “I LIMIT” “P LIMIT” keys as

follows:

V LIMIT Voltage limit

Press the "V LIMIT" key in the "LIMITS" field until

the symbol "U-const" flashes. The voltage limit can now

be adjusted to 1V steps by using the encoder wheel. If

PSP SERIES USER MANUAL

the "V LIMIT " key is now pressed for longer than 2s,

the voltage upper limit will again be set at "rating

voltage". To complete the input, press the "ENTER"

key. An inadvertently wrong-set limit setting can be

erased/reset with the " CE " key. As a result of this, the

previous set value will be indicated and the setting

menu exited. The "U-const" will no longer flash.

During operation (output On), the voltage output can

also be adjusted up to the set limit.

I LIMIT Current limit

Press the " I LIMIT" key in the "LIMITS" field until the

symbol "I-const" flashes. The current limit can now be

adjusted to 1mA, 2mA, 10mA ("fine") or 100mA

("norm", coarse) steps by using the encoder wheel. If

the "I LIMIT" key is now pressed for longer than 2s, the

current upper limit will again be set at "rating current".

To complete the input, press the "ENTER" key. An

inadvertently wrong-set limit setting can be erased/reset

with the " CE " key. As a result of this, the previous set

value will be indicated and the setting menu exited. The

"I-const" will no longer flash.

P LIMIT Power limit

Press the "P LIMIT" key in the "LIMITS" field until the

symbol "P-const" flashes. The power limit can now be

adjusted to 1 W steps by using the encoder wheel. If the

"P LIMIT" key is now pressed for longer than 2s, the

PSP SERIES USER MANUAL

power upper limit will again be set at "200 W". To

complete the input, press the "ENTER" key. An

inadvertently wrong-set limit setting can be erased/reset

with the " CE " key. As a result of this, the previous set

value will be indicated and the setting menu exited. The

"P-const" will no longer flash.

Attention: The current "I LIMIT" is adjusted

independently of its setting by the maximum output

power setting. The voltage upper limit does not

change.

C)"KEY INPUT" field settings

V SET Using the "V SET" key, the output voltage can be adjusted

up to the preset upper limit directly. For this the "V SET"

key must be pressed and held and the voltage changed

with the encoder wheel. If the "fine" F key is selected,

the changes occur in 10 mV, and 20mV steps. If

"norm" N key is selected, the changes occur in 1V

steps.

ENTER Each input via the "LIMITS" keypad is completed with the

"ENTER" key.

CE Any values incorrectly entered via the "LIMITS" keypad

can be reset with the " CE " key.

N The size of each setting step can be changed by using the

" N " ("Normal") key. In connection with the " F " key, so-

called mutual locking is achieved.

F If the " N " key is pressed, the "fine" symbol disappears
