Astrodyne Corp. has released a multi-package PMK225 line of high density switching power supplies that provide output power of 225W with active power factor correction.

The power supplies are designed to meet the space and performance needs in low- to moderate-power ITE systems and instrumentation applications. All models accept universal input from 90Vac to 264Vac and 6 models in each package style are available providing single outputs from 5- to 48Vdc.

The PMK225 series is approved for UL/EN60950-1 safety specifications. Utilizing high density SMT construction and providing power densities of up to 4W/cubic inch, the PMK225 offers reduced case sizes, which are up to 30 percent smaller than products with similar output power.

The PMK225 series may be ordered in either of three package styles, including U-Channel, fully enclosed or DIN Rail mounts. All models feature short circuit, overvoltage and over current protection and an integral power-good LED indicator. The PMK225 series operates at 100 percent capability to a temperature of 50C with 18CFM forced cooling.

Packed in 7-inch x 3.86-inch x 1.5-inch. (U-Channel) and featuring screw terminal input/output connections, the PMK225 are available for $99 in OEM quantities. Medical (PMMK225) UL/EN60601-1 versions are also available. Delivery is six weeks ARO.
