Calex announced the introduction of the 360 Watt TCM series of chassis mount DC-DC converters. Their wide 4:1 input range (9 to 36 V) makes them ideal for 12 V battery, 24 V process control and 28 V military COTS applications.
The chassis mount case is designed for backplane or enclosure mounting with or without DIN rails. Through holes are provided in the case for backplane mounting and a DIN adapter is available for DIN rail mounting. Threaded through holes are provided to allow the installation of a heatsink for extended temperature operation.
The TCM is fully isolated input to output, with an isolation voltage of 2250 V d.c. The output voltages available are 12, 24 and 28 V d.c. It is designed with the internal capacitance required to support 30 cm of connection wire on the input and output. For applications with greater wire length, the factory can assist with a solution.
With battery conservation in mind, the TCM offers an ON/OFF function which reduces the input current to 2 mA while the converter is in the OFF state. The switching frequency of the TCM is 200 kHz, and case operating temperature range is -40°C to 85°C.
The TCM is protected through over-current and short circuit protection, over-temperature protection with auto restart, and is fully encapsulated for environmental protection against dust, moisture and shock/vibration. It is backed by a five year warranty.
