Chassis-mount DC-DC converters for military COTS power electronics uses introduced by Calex
April 26, 2016
CONCORD, Calif., 26 April 2016. Calex Mfg. Co. Inc. in Concord Calif. is introducing the TCM series 360 Watt chassis-mount DC-DC converters for 12-volt battery, 24-volt process control, and 28-volt military commercial off-the-shelf (COTS) power electronics applications.
The TCM has a 4:1 input range, 9 to 36 volts DC. The chassis mount case is for backplane or enclosure mounting with or without DIN rails. Through holes come in the case for backplane mounting, and a DIN adapter is available for DIN rail mounting.
The TCM measures 3.20 by 4.53 by 1 inches, and has efficiencies of more than 96 percent. Threaded through-holes enable the installation of a heat sink for extended temperature operation. The TCM is isolated input to output. The isolation voltage is 2250 volts DC.
The TCM is designed with internal capacitance for one foot of connection wire on the input and output. With battery conservation in mind, the TCM offers an ON/OFF function which reduces the input current to 2 milliamps while the converter is in the OFF state.

The switching frequency of the TCM is 200 kHz. The case operating temperature range of the TCM is -40 to 85 degrees Celsius, and the storage temperature is -55 125 C.
The TCM is protected through over current and short circuit protection, over temperature protection with auto restart and encapsulated for environmental protection against dust, moisture and shock/vibration. The mean time between failures of the TCM is 5.4 million hours.
