Data sheet Power supply CP-T 24/5.0 Primary switch mode power supply The CP-T range of three-phase power supply units is the youngest member of ABBs 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 5 A and efficiency of up to 89 %. As in the case of all products, they are designed for an ambient temperature of up to 70 C.

Thus, they can be optimally adapted to the application, e.g. compensating the 5 voltage drop caused by a long cable length. 4 Indication of operational states OUTPUT LOW: red LED - output voltage too low OUTPUT OK: green LED - output voltage OK 6 5 Circuit diagram 6 Wide input range INPUT L1, L2, L3, PE: terminals - input 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 potentiometerOUTPUT Adjus 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 LEDOUTPUT O is lightening during proper operation, i. e. when the output voltage exceeds 75 %. The red LEDOUTPUT LO 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 contact13-14 (max. 60 V DC / 0.3 A) is ON when the output voltage exceeds 19.4 V. 2 - Power supply CP-T 24/5.0 Data sheet 2CDC 271 043 S0009
