Astrodyne has added the OFM Series of open frame modular switching power supplies that provide output power of 5W, 10W, 15W, and 22W. Dimensions vary from 2.28 in. x 1.77 in. x 0.83 in. for the 5W models to 2.0 in. x 3.5 in. x 0.8 in. for the 22W models.
All models accept universal input from 85-265Vac and 28 models are available that provide single outputs of 5Vdc to 24Vdc. They are also offered with dual ±12Vdc or ±15 Vdc outputs.
The OFM Series provides an economical power solution, and are pin out and size compatible to more costly encapsulated modules. The OFM Series features an integral power-good LED indicator and output adjustment potentiometer and will operate over the ambient temperature range of 0 to 45 ° C without forced cooling or output power derating. All models contain over-voltage and short circuit protection circuitry and internal input filtering.
The OFM Series is fully approved to UL/EN60950-1 safety specifications. The OFM Series are also available in medically-approved (OFM/M) versions.
