Calex Introduces Compact High Efficiency 2100 Watt DC/DC Converter

By Caroline Rees / 05 Mar 2014

2100 Watt DC/DC ConverterCalex has introduced the new MBH series of DC/DC Converters, which are capable of delivering up to 2100 Watts in a low profile 9.0″ x 6.5″ x 1.25″H ruggedized chassis mount package. The module weighs only 3.3 lbs. making the MBH ideal for harsh shock and vibration environments in both COTS military and industrial applications. The MBH Series’ high efficiency, up to 97%, is accomplished through the use of high efficiency synchronous rectification, advanced electronic circuitry and thermal design resulting in a compact, highly robust solution backed by Calex’s Five Year Warranty. The operating temperature range for the MBH is -40 to 95C with storage of -55 to 100C.

The MBH Series consists of five models. Three of the models offer a 10 to 16VDC input range making them ideal for 12V mobile applications. The outputs are 28VDC at 40, 60 and 75 Amps. The remaining two models have a 23 to 32VDC input range with output voltages of 12 and 13.5VDC, both at 100 Amps. All models are highly regulated and no minimum load is required for any of the MBH models. The MBH topology utilizes a fixed switching frequency of 400 kHz. All models feature ON/OFF, non latching output over-voltage protection, thermal shutdown with auto restart, input reverse polarity protection, operating surge protection and short circuit protection.
