INSTALLATION MANUAL

PSE series AC inputs

1 Before installation

Before installation, please read this section

and minimum section 2. This installation

manual shall also be read together with the

datasheet of the product. Download the

datasheet from www.polyamp.com and check

the File archive where in section Datasheet

you will find PSE100AC.pdf .

If any problem occurs during installation

please check section 10 Trouble shooting.

The product is labelled as below example:

The power supply type name consists of

model name PSE60 and PSE100 followed by

input code and output voltage. Two examples:

•”Type: PSE100AC24” has input

code ”AC” and nominal output

voltage 24 Vd.c.

•”Type: PSE60ACW12 ” has input

code ”ACW” and nominal output

voltage 12 Vd.c.

The Options are block letters separated by

comma(,). You will find explanation within

this manual what the letter code means.

The input states the nominal input voltage

and maximum input current at any

conditions. It means the output is adjusted

+10% above nominal voltage and close to the

current limit, which is the stated output

current +5% and a lowest input voltage level.

Input range is the input range that the unit

can operate normally.

Output indicates the nominal output voltage

and the rated current.

The output is current limited with a so

called rectangular characteristic. When the

current limit is reached, which is adjusted to

+5% of above mentioned nominal output

current, this is the maximum current that will

continuously flow. The output voltage drops

very quickly down towards zero volt (depends

on the series resistance of the load circuit as

the unit can be regarded as a constant current

generator at over current condition). We have

no time limit on over current condition.

Temperature range is the rated operation

temperature at 100% load condition.

Input, output and case are galvanically

separated from each other.

This is a Class I insulation system, which is

dependent of correct earth connection on the

input. All outputs are insulated from case with

minimum 2000 Vd.c.

Series number is stamped on the panel under

the connector

1.1 Cable and pin dimensioning

The PSE series is using a DIN 41621 H15

connector intended for 3HE Euro format

mounting. Each pin has a continuous current

rating of 15 A @+55°C and 12 A @+70°C

ambient temperature.

The Uout pins are internally parallel

connected and can therefore supply more

current or two different loads. If the unit is

equipped with sense option S this must be

connected to one of the loads or a distribution

point.

1.2 Inrush current limit

The input capacitors are charged through

an NTC resistor to reduce the input

current during start up. All models has an

”output soft start” that do not increase the

input current above the unit rated current

during start up (approx. 0.1s).

1.3 Input Fuse

There is a fuse inside the the power

supply. If that fuse blows it’s an indication

of a fault in the unit. Replace with new

unit and send it back for repair, see

section 10.

INSTALLATION MANUAL

PSE series AC inputs

•If you intend to use alarm feature,

please consult section 7 Under

voltage Alarm on page 10.

5. Connect the input cables. Bundle input

cables together separated from the output

cables.

6. Switch on the input voltage.

Beware of hazardous voltages!

The output voltage can be adjusted between

±10% of nominal output voltage with the

potentiometer marked V.ADJ on the front

panel. Clockwise turn increases the output

voltage. The potentiometer has 15 turns. If

you have connected units in parallel on the

output, the procedure of adjusting the output

voltage is described in “Adjusting output

voltage when units are paralleled on the

output” on page 7.

3 Parallel connection

If a redundant power supply system is

requested, two or more converters can be

connected in parallel. To achieve redundancy

the number of converters must be

dimensioned to carry the whole load even if

one converter is faulty. The option C or CR

series diode on the output must be provided.

Connect your load to the + output after the

series diode (cathode).

Another reason for connecting two or more

converters in parallel is to get more power.

The option C must be provided and use the

output with series diode. When the series

diode C or CR option is used the Sense option

S, see section 5 page 9, cannot be used.

3.1 Series diode on the output,

option C

A series diode is necessary if the output is

connected in parallel with another power

supply or if you require redundant operation.

If a converter breaks down with an internal

short-circuit on the output and other

converters are connected in parallel on the

output, the broken unit will short-circuit the

others if the series diode is not used. This

might cause excessive heat or even fire in the

faulty unit.

The series diode protects the converter output

from external voltage sources.

If the series diode is used, we recommend to

use the alarm function option B alarm circuit.

The alarm relay will switch to ”ALARM” on

the faulty unit if one power supply breaks

down in a redundant power supply system.

Otherwise there will be no alarm indication

from a faulty power supply unless all units are

in current limit.

3.2 Series diode with series

resistor, option CR

This option is an extension of 3.1 Series

diode. When several PSE units are connected

in parallel with so called “hot plug in” in 19”

sub-rack, a built in series resistor and series

diode is provided that will automatically

balance the current between units.

The series resistor will provide the Ud

function described in section 3.4 and Figure

4. Thus no special cable arrangments are

needed with this CR option.

3.3 Output under voltage alarm

If one DC/DC converter fails in a redundant

power system an alarm signal should be

detected.

The PSC has a logic open collector alarm to

provide a logic signal. An optional relay dry

contact output, see section 8 page 10.

The figure 2, next page shows a N+1 system

with two units for the load and one for the

redundancy. Each Power supply has a built in;

series diode (C), balancing resistor (R) and

alarm Relay option B. The alarm is cascade

connected.

With the CR option a hot plug-in can be

achieved if the output voltage is correctly

adjusted. Use instruction section 3.6 -3 below.
