Application The primary switch mode power supply offers two voltage input ranges. 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 2CDC 271 024 F0008Power supply CP-E 12/10.0 Primary switch mode power supply Data sheet Operating mode By means of the potentiometer OUTPUT Adjust the output voltage can be adjusted within a range of 11.4 to 14.5 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. The red LED OUTPUT LOW is lightening when the output voltage is too low. Switch single/parallel for selection of single or parallel operation. Installation Mounting 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 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 The devices have to be mounted horizontally with the input terminals on the bottom. In order to ensure a sufficient convection, the minimum dis tance to other modules should not be less than 25 mm in vertical and hori zontal direction. 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, pr ovide 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 pr otection. 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).
