Calex Introduces Ultra Wide 8:1 Input Range DC-DC Converters

Calex Mfg. Co., Inc. introduced the dual output AHW series of dc-dc converters. The AHW features what the company says is an unprecented continuous input range of 9 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 AHW provides a unique solution for those requiring an ultra wide input range allowing the converters to be used in a variety of applications from mobile electronics to telecommunication.

The AHW series provides a number of features in addition to the 8:1 input range. All models have a -55 to +100°C 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, unique for units in this wattage range, 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". 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. Units are available from stock to eight weeks.
