DESCRIPTION
The PSADF series of AC/DC power supplies offers 7 Watts of output power in an encapsulated design. These modules have a
single output and a universal input range of 85-265VAC. Other features include continuous short circuit protection, over voltage
protection, and output current limiting. These units are also EMC EN61000-4 (-2,-3,-4) and EMI EN55022 level B approved. The
compliance to these EMI specifications minimizes system design time, cost, and eliminates the need for external filter components.
The PSADF series has IEC/ EN/UL 60950-1 safety approvals, which qualifies this product for worldwide markets. This series has a
wide variety of applications including both commercial and industrial with a MTBF of 330,000 hours.
