Application

The primary switch mode power supply CP-C.1 has a wide AC or DC input voltage range. Furthermore the CP-C.1 is equipped with capacitors that ensure a hold-up time of at least 40 ms. This enables worldwide usage and permits safe operation in fluctuating networks and battery-powered applications.

The CP-C.1 has a robust metallic housing and a reliable construction which enables usage in harsh industrial environments. The power reserve of up to 50 % enables trouble-free starting of heavy loads eliminating the need of usage of an oversized power supply.

Power reserve

The primary switch mode power supply CP-C.1 is equipped with a power reserve functionality to handle the start-up of particulary heavy loads (e.g. of a capacitive load or a motor). To ensure that heavy loads are started up, the CP-C.1 delivers additionally up to 50 % of the rated output current to secure the operation of the application. This status is displayed by the yellow LED labelled POWER RESERVE I > IR.

Signaling output

For the communication of the status of the power supply the CP-C.1 is equipped with a relay output to signal output OK as well as a transistor output to indicate when the power reserve is active. These signals can be used for communication to a higher level control system e.g. a PLC.

Adjustable output voltage

The CP-C range power supplies feature a continuously adjustable output voltage of 22.5 to 28.5 V DC. Thus they can be optimally adapted to the application, e.g. compensating the voltage drop caused by a long line length.

Operating mode

Parallel operation

There are two main reasons for a parallel connection of power supplies:

– Increase of power – Redundancy

Up to 5 devices of the same type can be connected in parallel. For safe and reliable operation it is important to follow the

recommendations given in the following section.

Parallel connection of power supplies for increased power

If the current required by the load is higher than a single power supply can deliver, for example after the expansion of an existing installation, an increase of the output power can be obtained by connecting power supplies in parallel. The following prerequisites have to be fulfilled when connecting power supplies in parallel for the purpose of increased power:

– The paralleled devices must be of the identical type. – Repeated voltage drops on the supply lines or at the terminals would lead to unbalanced load at the common connection

point. To prevent this, you have to observe the following when connecting the power supply units:

– Identical lengths of the load supply lines. – Identical conductor cross sections of the load supply lines. – Terminal screws have to be fastened with the same torque to guarantee equal contact resistances. – The output voltages of the power supplies must not differ by more than 50 mV. Otherwise, safe operation is not

possible.

Installation for increased power Incorrect wiring for increased power

Important:

The devices must not be connected directly to each other! This could lead to an overload of the terminals since the terminals are dimensioned for the maximum output current of a single power supply only. Always use a common connection point!

Data sheet | Power Supply CP-C.1 24/20.0 - 5

Parallel connection of power supplies for redundancy

Several power supplies are connected in parallel in order to guarantee continuous operation of the system if one power supply fails. CP-C.1 can be used in two different redundancy modes depending on what type of redundancy is required:

– Simple redundancy, n+1 – True redundancy

Simple redundancy, n+1 redundancy

For simple or n+1 redundancy, the power supplies are connected in parallel like for the increase of capacity. To achieve redundancy the current required by the load must not exceed the maximum output power of one single power supply (in case of “1+1 redundancy”) or n power supplies (where n is max. 4).

We recommend connecting the primary sides of the power supplies to different phases of the mains in order to obtain continuous operation of the system if one phase fails.

Simple redundancy or n+1 setup

 (n-1) * I

Load

2CDC 272 005 F0215

True redundancy

True redundancy gives higher system availability compared to simple or n+1 redundancy.

In a true redundancy setup the power supplies are decoupled from each other with decoupling diodes. This protects the individual power supplies from affecting each other in case of failure of one unit or short cirucit on the secondary side or in the wiring.

For two inputs of up to 20 A and one output up to 40 A the ABB redundancy unit CP-A RU (available as an accessory) can be used.

The inputs of these units are connected to the terminals L+ and L- of the power supplies. The loads are supplied directly from the outputs of the redundancy unit.

Electrical connection

Connect the input terminals "L“ to line and "N" to neutral conductor or to + and - with DC supply "+" to "L" and "-" to "N". The protective earth conductor PE must be connected before putting the device into operation. The installation must be executed acc. to EN 60950. Provide a suitable disconnecting device (e. g. line protection switch, MCB or fuse) in the supply line. The input side of the power supply is protected by an internal input fuse.

The wiring, cable choice and their protection shall comply to the local electrical standard. We recommend choosing the conductor cross-section as large as possible in order to minimize voltage drops. Check the polarity. The device is overload, short-circuit and open-circuit proof. The secondary side of the power supply is electrically isolated from the input and internally not earthed (SELV) and can be earthed for PELV.

Safety instructions and warnings

In operation pay attention to:

– Do not modify the installation (primary and secondary side)! High current! Risk of electric

arcs and electric shock (danger to life)! – Risk of burns: Depending on the operation conditions the housing can become hot. – The device contains no user serviceable parts. In any case of device malfunction please

send the unit back to manufacturer.

The device must be installed by qualified persons only and in accordance with the specific national regulations (e. g. VDE, etc.).

The CP-C.1 is a chassis-mounted unit. It is maintenance-free and does not contain any integral setting elements and should therefore not be opened.

Before any installation, maintenance or modification work:

– Read the operating and installation instructions carefully and completely! – Disconnect the system from the supply network and protect against switching on!

Before start of operation the following must be ensured:

– Connection to mains or DC supply according to the speciﬁc national regulations for class

of protection I. – Power supply cables and unit must be sufﬁciently fused. A disconnecting device has to

be provided for the end product to disengage unit and supply cables from supply mains

if required. – The protective earth conductor must be connected to the terminal PE. – Rate the output lines for the output current of the power supply and connect them with

the correct polarity. – In order to ensure sufﬁcient convection the distance to the other devices has to be

considered.

Attention! Improper installation/operation may impair safety of personnel and cause operational difficulties or destruction of the unit.

Attention! Danger to life!

Disconnect the system from the supply network before executing any works at the device and protect against switching on! The power supply contains components with high stored energy and circuits with high voltage! Do not introduce any objects into the unit and do not open the unit.

With some units of this range the output is capable of providing hazardous energy. Ensure that the service personnel is protected against inadvertent contact with parts carrying energy.

If the internal fuse is blown most probably the device is defect. In this case an examination of the device by the manufacturer is necessary.

The switch mode power supply CP-C.1 is able to supply at 24 V DC output voltage and at an ambient temperature of

– ≤ 40 °C a continuous output current of typ. ≤ 26 A – ≤ 60 °C the rated current of 20 A

At ambient temperatures of > +60 °C the output power has to be reduced by 3.5 % per Celcius degree temperature increase.

At thermal overload the device will switch-off as soon as the internal temperature exceeds the acceptable level. The exact ambient temperature threshold depends on the mounting position and load of the power supply.

If the switch mode power supply is loaded with an output current > 26 A, the operating point is passing through the U/I characteristic curve shown.

The device is equipped with an overtemperature protection function. It will switch-off as soon as the internal overtemperature protection function is activated.
