Calex Introduces New 150W Chassis Mount DC-DC Converter
Calex Manufacturing Company Inc. announced the HCM Series of high power density chassis mount dc-dc converters. These 150W rugged, encapsulated dc-dc converters are well suited for harsh industrial and COTS military applications. All 10 models in the series offer a wide 4:1 input range, from 9 to 36Vdc and 18 to 75Vdc, make the units well suited for 24V industrial, 12 and 24V battery applications and 48V power sources. The output voltages available are 3.3, 5, 12, 15 and 24Vdc. All models are isolated input to output. The MTBF for all models is over 1M 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 a very favorable 3C 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 -40C to +100°C. The case dimensions are 4.3 x 3.2 x 1.0". The HCM weight is 11.4 ounces. RoHS and non-RoHS construction is available.
In addition to the mechanical advantages of the HCM enclosure, the units offer a number of electrical features often not 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 sense; and output voltage trim capability.
Lead time for the HCM models is stock to 8 weeks.
