Calex has announced the HCM Series of high power density chassis mount DC/DC Converters. These 150 watt rugged, encapsulated DC/DC converters are ideal for harsh industrial and commercial off-the-shelf military applications.All 10 models in the series offer a wide 4:1 input range, from 9 to 36 V DC and 18 to 75 V DC, making them ideal for 24 V industrial, 12 and 24 V battery applications and 48 V power sources. The output voltages available are 3.3, 5, 12, 15 and 24 V DC. All models are isolated input to output. The MTBF for all models is over one million hours.
The versatile enclosure of the HCM Series provides a "clamp" style recessed barrier strip which secures wire without twisting. The enclosure can be mounted with the barrier strip facing up or down depending on what is preferred for the application. The excellent thermal characteristics of the enclosure provide 3ºC per watt dissipated thermal impedance. The enclosure also has threaded inserts for securing a heatsink if needed for extended temperature applications. The case operating temperature range for the HCM is -40ºC to +100ºC.
The case dimensions are 110 x 82 x 26 mm and the weight is 325 g. RoHS and non-RoHS construction is available.
In addition to the mechanical advantages of the enclosure, the HCM offers a number of electrical features not often found in chassis-mount units:
- Volt-seconds clamp and fast over voltage protection
- Pulse by pulse current limiting
- Short circuit frequency foldback
- Dead short shut-down
- Over-temperature protection
- Auto-softstart
- Remote sensing
- Output voltage trim capability
