The buffered power supply SSE902405 is suited for medium-sized load which have to be supplied constantly. Through buffering load currents during line voltage faults, peak loads or switching operations, interferences at controls, caused by short blackouts, can be avoided. The integrated Buffer capacitors bypass short power failures and supply the consumer with energy, which guarantees a constant power supply. During an undisturbed mains the internal power supply supplies the facility with an output voltage of 24V. The outputs are short circuit and open DC circuit proof.
