Four versions with a 3 Phase maximum current limited output deliver 5A, 10A, 20A or 40A without derating up to +55C. The output can be grounded via a third common output terminal. The LED signal on the front panel indicates that the DIN-Rail output voltage remains within the wide adjustable range from 22.5 to 29.5VDC. The units are covered by international safety certificates and are intended for worldwide use. In power-hungry applications, Power Supply the units can be connected in parallel with no need for additional components. Selection Guide (1) Part nom.
