These mod- ules are UL, CSA, and VDE approved for telecom applications, and rated at 30W or 8A. The 18V to 60V input range allows easy integration into many distrib- uted power applications which utilize 24V bus architectures. Standard output voltages range from 1.8V to 15V, and are each adjustable by up to ±10%. Operating features include a Remote On/Off control, an under-voltage lockout (UVLO), and a differential re- mote sense. Protection features include an output current limit, short-circuit protection, and over-temperature shut- down. A 330µF output capacitor is required for proper operation.
