CONCORD, Calif., 10 Feb. 2015. Calex Mfg. Co. Inc. in Concord Calif., is introducing the MTW series of power supplies for 28-volt COTS military applications, as well as for 12 and 24-volt battery powered applications.
The MTW power electronics DC-DC converter offers 360 Watts of output power in a standard half-brick case. Available output voltages are 12, 15, 24, and 28 volts DC. The input range for all models is 9 to 36 volts DC with no derating at 9 volts input. The MTW is isolated input to output and provides a precisely regulated output.
The converters high efficiency and high power density come from high-efficiency synchronous rectification technology, advanced electronic circuit, packaging and thermal design thus resulting in a high reliability product.
Converter operates at a fixed frequency and follows conservative component de-rating guidelines. The efficiency of the MTW is 95.7 percent, easing the job of thermal management of the converter.
The case measures 2.4 by 2.5 by 0.50 inches with a metal surface for heat transfer in extended-temperature applications. The operating temperature range of the MTW is -40 to 100 degrees Celsius. The switching frequency of the MTW is 200 kHz.
Output voltage accuracy is +/-1.5 percent. Turn-on overshoot is 0. The temperature coefficient of the MTW is 0.015 percent typical. Output noise is 1 percent of volts output peak to peak.
