Power supply CP-T 24/10.0

Primary switch mode power supply

The CP-T range of three-phase power supply units is

the youngest member of ABB’s power supply family. In

terms of design and functionality, the new range perfectly

supplements the existing products and extends the

range appropriately. The devices can be supplied with

a three-phase voltage as well as with two-phase mains.

Here, ABB offers a power supply unit with 24 V DC

output with 10 A and efficiency of up to 90 %. As in the

case of all products, they are designed for an ambient

temperature of up to 70 °C.

Optimised for worldwide applications: The CP-T
power supply units can be supplied for a wide range
of AC and DC voltages. Both kinds of power supply
(three-phase and two-phase) are possible.

Application

The primary switch mode power supply offers a three-phase supply voltage range of 3 x 400-500 V AC. A two-phase power
supply is also possible and it can also be supplied by 480-820 V DC. Furthermore, this power supply unit is equipped with
two generous capacitors, which ensure mains buffering of at least 20 ms. That is why the devices can be used worldwide
also in high fluctuating networks and battery-powered plants.

Operating mode

By means of the potentiometer "OUTPUT Adjust" the output voltage can be adjusted within a range of 22.5-28.5 V DC.
Thus, the power supply can be optimally adapted to the application, e.g. compensating the voltage drop caused by a long
line length.

The green LED "OUTPUT OK" is lightening during proper operation, i. e. when the output voltage exceeds 75 %.

The red LED "OUTPUT LOW" is lightening when the output voltage is less than 70 % of the rated output voltage.

Two-phase supply is permissible with a derating of the output to 75 %.

Signalling contact "13-14" (max. 60 V DC / 0.3 A) is ON when the output voltage exceeds 19.4 V.

Installation

The device must be installed by qualified persons only and in accordance with the specific national regulations (e.g. VDE, etc.).
The devices are maintenance-free chassis-mounted units.

Before installation

DANGER!

Components with high stored energy and circuits with high voltage

Danger to be electrocuted!

► Disconnect the system from the supply network and protect against switching on before any installation,

maintenance or modification work.

► Do not introduce any objects into the unit and do not open the unit.

► Ensure that the service personnel is protected against inadvertent contact with parts carrying energy.

Mounting

The switch mode power supply can be snapped on a DIN rail (TH 35-15 or TH 35-7.5 according to IEC/EN 60715) as
shown in the accompanying picture. For that the device is set with its mounting rail slide on the upper edge of the mounting
rail and locked by lifting it downwards.

2CDC 272 016 F0010

Demounting

Remove the switch mode power supply as shown in the accompanying picture. For that the latching lever is pulled
downwards by means of the screwdriver. Alternatively you can press the unlock button to release the device. Then in both
cases the device can be unhinged from the mounting rail edge and removed.

2CDC 272 017 F0010

Mounting position

The devices have to be mounted horizontally with the input terminals on the bottom. In order to ensure a sufficient
convection, the minimum distance to other modules should not be less than 25 mm (0.98 in) in vertical and horizontal
direction.

Connection diagram

Preparations:

– Connect to main according to the specific national regulations.

– Power supply cables and unit must be sufficiently fused. A disconnecting device has to be provided for the power

supply to disengage unit and supply cables from supply mains if required.

– We recommend to choose the cable section as large as possible in order to minimize voltage drops.

– In order to ensure sufficient air-cooling the distance to other devices has to be considered.

Instructions:

1. Connect the input terminals L1, L2 and L3.

2. Connect the protective earth conductor to the terminal o (protection class I).

3. Provide a suitable disconnecting device (e.g. line protection switch) in the supply line acc. to IEC/EN 60950.

4. Rate the lines for the maximum output current (considering the short-circuit current) or provide a separate fuse
protection. The input side is protected by an internal input fuse.

5. Observe the polarity.

The device is overload, short-circuit and open-circuit proof. The secondary side of the power supply unit is electrically
isolated from the input and internally not earthed (SELV) and can therefore be earthed by the user according to the needs
with L+ or L- (PELV).

Operation

DANGER!

High current

Risk of electric arcs and electric shocks!

► Do not modify the installation (primary and secondary side).

► Intended use.

CAUTION!

Depending on the operation conditions the enclosure can become very hot

Risk of burns!

► In order to ensure sufficient air-cooling the distance to other devices has to be considered.

The device is intended for use as a primary switch mode power supply. Any other usage is not supported by the
manufacturer. Other usage may impair safety and cause operational difficulties or destruction of the unit.

Service

The internal fuse is not user-replaceable. If the internal fuse blows, most probably the device is defective. In this case, an
examination of the switch mode power supply by the manufacturer is necessary.

The switch mode power supply CP-T 24/10.0 is able to supply at 24 V DC output voltage and

– at an ambient temperature of:

≤ 60 °C a continuous output current of approx. 10 A

– at ambient temperatures of:

60 °C < Ta ≤ 70 °C the output power has to be reduced by 2.5 % per °C temperature increase.
