3 FUSING

REDARC recommend using MIDI style bolt down fuses as they

ensure a low resistance connection. The REDARC FK40 and FK60

fuse kits are recommended.

Blade type fuses are not recommended as they can result in a high

resistance connection which causes excess heat and may damage

the fuse holder and/or the wiring. Self-resetting circuit breakers

are not recommended as they may trip prematurely and continue

to cycle until failure, due to the heat generated by the current

ﬂowing through the wires.

4 PRODUCT FUNCTION

The DPS1225/DPS1240/DPS2410/DPS2420 is a DC-DC power supply designed to run electrical loads.

The input voltage of the DPS can be above, below or equal to the output voltage making it ideal for

running equipment where speciﬁc load voltages or extreme voltage drop are an issue.

The DPS is also designed to isolate the main battery from the load when the vehicle is turned off to avoid

ﬂattening the vehicle’s starter battery.

4.1 Display Panel

The front panel features 4 LEDs to display the voltage level and output status.

LED State ‘Voltage Level’ LEDs ‘Output Status’ LED

Off Unit has no Power Output is off

Blinking Unit is in Standby Unit is supplying power

On Unit is on and can supply power

When blinking, the ﬂash duty-cycle of the ‘Output Status’ LED will increase to reﬂect the amount of

current being supplied - If the LED is ON solid, the unit is supplying full power (e.g. 25A for a DPS1225).

4 PRODUCT FUNCTION

4.2 Unit Performance Characteristics

The DPS Should be mounted to the vehicle’s chassis to allow adequate heat-sinking. If the DPS

experiences extreme ambient temperatures its output power may decrease until a steady-state is

achieved. Better heat-sinking will enable greater power output.

(185°F)

The DPS is able to overcome substantial voltage drop by acting as a voltage booster. Voltage drop (as

a result of inadequate input cable size) can cause excessive heat to be generated in the wiring. To

ensure the wiring is protected the DPS will try to limit the difference between input and output voltage

by reducing the current draw on the input of the unit. To ensure full power output is maintained suitable

cable size (as outlined in Section 5.8) should be used.

4.3 Error Codes

In the event of a fault with the unit, installation, input supply or output loads, both the External LED and

ALL the LEDs on the unit will ﬂash to indicate the fault type. Flashing sequences are described in the

table below.

LED State Description

1 ﬂash (1 ﬂash followed by 3.5 second off) Internal Hardware Fault

2 ﬂash (2 ﬂash followed by 3.5 second off) Not Used

3 ﬂash (3 ﬂash followed by 3.5 second off) Unit over temp fault

4 ﬂash (4 ﬂash followed by 3.5 second off) Output over voltage

5 ﬂash (5 ﬂash followed by 3.5 second off) Not Used

6 ﬂash (6 ﬂash followed by 3.5 second off) Input over voltage

7 ﬂash (7 ﬂash followed by 3.5 second off) Reverse polarity

NOTE: The unit will operate optimally below 55°C (131°F) with good airﬂow. At higher temperatures the

unit will de-rate output current.

NOTE: Appropriate connections must be made to the wires with continuous current ratings as per the

speciﬁcations table on page 4.

5 INSTALLATION

The DPS cannot be installed in direct heat environments such as the vehicles engine bay, the DPS

performs at its best when the unit is mounted to the chassis for external heat sinking.

The DPS1225/DPS1240/DPS2410/DPS2420 has 6 wires and should be installed as described over the

following pages.

5.1 RED wire—Input Source Positive

The RED wire should be connected to the positive

input from the vehicle’s starter battery.

Appropriate size fuses should be used as per

the speciﬁcations table on page 4.

5 INSTALLATION

5.2 BLUE wire—Ignition Control

The BLUE wire should be connected to the vehicle’s

ignition or, if required, a dedicated ON/OFF switch.

When connected in this way, the power supply will only

run the connected loads when the vehicle ignition is ON,

guaranteeing that the power supply will not drain the

start battery.

5.5 BLACK wire—Common Ground

The BLACK wire should be connected to a ground point that is

common to both the start battery and the load. This point may

be on the chassis of the vehicle or on the chassis of the trailer

depending on your installation requirements.

5.6 GREEN wire—Optional External LED

The GREEN wire is provided to optionally connect an external

indicator LED which can be mounted away from the unit (for

example on the vehicle’s dashboard). The DPS will limit the

current supply by the GREEN wire to 6 mA so a standard green

LED can be connected directly between the GREEN wire and the

common ground. An LED with a series resistor can also be used

but the resistor value should be less than or equal to 1000 Ohms

(an LED with a built-in 1000 Ohm series resistor is typically

referred to as a “12Volt LED”).

Connect the positive lead of the LED to the green wire, and the

negative lead to the common ground.

This LED will illuminate constantly when the DPS is supplying

power, it will ﬂash a fault code if the DPS has detected an error.

5.7 Earth Isolation

If the DPS is installed on a vehicle ﬁtted with an earth isolation switch, the BLACK wire must run to

chassis earth/ground and NOT the supply battery’s negative post. This ensures that the DPS is also

disconnected when the isolation switch is activated.

5.9 Wiring

The heavy gauge wires on the DPS1225, DPS1240, DPS2410 and DPS2420 unit carry peak currents of up

to 40A and it is important to make a good, low resistance, electrical connection that will not degrade over

time. Failure to make a good, reliable contact may result in breakdown of the wire insulation and cause

a short circuit, or worst case a ﬁre. We recommend that this activity be undertaken by an appropriately

trained person.

REDARC recommends using a soldered butt splice crimp connection that is covered with heatshrink. Do

not use standard red/ blue/yellow blade connections as they are not rated for either the current required

or gauge of wire supplied on the unit.

Crimping provides good mechanical connection; soldering provides a long lasting electrical connection

and forming of the heatshrink will reduce the risk of shorting/contact with your vehicle chassis.

Figure 4: Ensure Good Wiring Connection

Crimp both wires to the butt splice using

single-indent type crimpers. Fold the cable over

before inserting into the butt-splice as required.

Single-indent crimpers should also be used

on any lugs used.

Solder the wires to the butt splice. Ensure that a

good connection is made. Keep heatshrink away

until after soldering is complete and has cooled.
