These modules are UL, CSA, and VDE ap- proved for telecom applications, and rated at 30W or 8A. The 18V to 60V input range allows easy integration into many distributed 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.
