This enables the supply with AC or DC. Furthermore it is equipped with two generous capacitors, which ensure mains buffering of at least 30 ms (at 230 V AC). That is why the devices can be used worldwide also in high fluctuating networks and batterypowered plants. ABB 1 Power supply CP-E 24/20.0 Primary switch mode power supply Data sheet Operating mode By means of the potentiometer OUTPUT Adj" the output voltage can be adjusted within a range of 22.5 to 28.5 V DC. Thus, the power supply can be optimally adapted to the application, e.g. c ompensating the voltage drop caused by a long line length. The green LED OUTPUT OK" is lightening during proper operation. The red LED OUTPUT LOW" is lightening when the output voltage is too low. Switch single/parallel" for selection of single or parallel operation. Signalling contact 13-14 (max. 60 V DC / 0.3 A) is ON when the output voltage is more than 75 %. Installation Mounting 2CDC 272 017 F0b08 The switch mode power supply can be snapped on a DIN rail 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. Demounting 2CDC 272 018 F0b08 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. Mounting position 2CDC 272 021 F0b08 The devices have to be mounted horizontally with the input t erminals on the bottom. In order to ensure a suffi cient convection, the m inimum distance to other modules should not be less than 25 mm in vertical and horizontal direction. 2 ABB Power supply CP-E 24/20.0 Primary switch mode power supply Data sheet Installation Electrical connection Connect the input terminals L and N. The protective earth conductor PE must be connected. The installation must be executed acc. to EN 60950, provide a suitable disconnecting device (e. g. line protection switch) in the supply line. The input side is protected by an internal input fuse. Rate the lines for the maximum output current (considering the shortcircuit current) or provide a separate fuse protection. We recommend to choose the cable section as large as possible in order to minimize voltage drops. Observe the polarity. The device is overload, shortcircuit and opencircuit 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). Connection diagram L N L+ PWM L- PE PE N L 2CDC 272 024 F0b08 1314 L+ L+ L- L- L+, L L, N 13-14 PE Output voltage Input voltage Signalling contact for output voltage OK Protective earth Safety instructions and warnings 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. Disconnect system from supply network! Before any installation, maintenance or modification work: Disconnect the system from the supply network and protect against switching on. Before start of operation: Attention! Improper installation/operation may impair safety and cause operational difficulties or destruction of the unit. Before operation the following must be ensured: 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. The protective earth conductor must be connected to the terminal PE (Protection class I) The secondary side of the power supply unit is not earthed and can be earthed by the user according to the needs with L+ or L-. Rate the output lines for the output current of the power supply and connect them with the correct polarity. In order to ensure sufficient air-cooling the distance to other devices has to be considered. In operation: Do not modify the installation (primary and secondary side)! High current! Risk of electric arcs and electric shocks (danger to life)! Risk of burns: Depending on the operation conditions the enclosure can become very hot. 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. Attention! High voltage! Danger to life! The power supplies contain 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.
