The dual output AHW series of DC/DC converters from Calex Mfg. Co., Inc. (Concord, CA) feature a continuous input range of 9VDC to 75VDC. The AHW is isolated input to output and provides a regulated +/-5, +/-12, and +/-15VDC output at +/-400mA, +/-167mA, and +/-133mA. All models will fully regulate down to a no-load condition. The input to output isolation voltage is 1544VDC. The converters are ideal for a variety of applications from mobile electronics to telecommunication.

The AHW series have a -55 to 100ºC operating temperature range and are specified over the full temperature range. The design ulitizes planar magnetics and provides an all ceramic solution for long term reliability. The open frame construction can withstand extremely aggressive solvents and cleaning cycles applied during customer's manufacturing process. All models feature ON/OFF and TRIM. The TRIM range is -20 to +10%.

The AHW dimensions are 1.22" x 0.78" x 0.28"H. The converters are designed utilizing solder ball pins for surface mount installation. Once installed, enough space is provide under the converter to allow for PCB population directly underneath the DC/DC converter.
