4-W encapsulated supply suits PCB applications

The PK4 series of ac/dc switching power supplies offer 4 W output power in a 1.44 x 1.06 x 0.67-in. encapsulated case. They suit small size PCB applications. The supplies operate from a 85 to 264 Vac input, at 47 to 440 Hz. The single output models available are 3.3, 5, 9, 12, 15, and 24 Vdc. Dual out­put models are +5/+3, +12/+5, ±12, and ±15VDC.

The power supplies feature output over-voltage protection and short-circuit protection. The units are encapsulated with a thermally conductive potting compound in a plastic resin and fiberglass case that meets UL94V-0. They are rated for 3,000 Vac isolation, are UL approved, and RoHS compliant.
