MTM Power’s latest DC/DC converters offer base plate cooling

MTM Power introduced the PCMDNI300 series of DC/DC converters without galvanic isolation, targeting decentralized power applications in vehicles and closed sub-systems in rolling stock. Their wide input voltage range from 28Vdc to 160Vdc enables the use of batteries from 36 to 100 V. The devices can be operated in a temperature range from -40° to +70 °C without derating, and have an efficiency of up to 96 %.

The completely vacuum-encapsulated converter (EP 1 987 708, U.S. Patent No. 8,821,778 B2) is protected against condensation, conductive dust, and other environmental conditions, and is available with output voltages of 12 VDC or 24 VDC. Due to the rugged design with contact-cooling (BPC technology), it is possible to reduce the power loss via heat dissipation through the mounting plate while increasing the life-time of the devices at the same time. As an option a self-cooling version with integrated heat sink is also available. A remote control input on the primary side allows a low power switch-on of the output voltage at high loads.

For the use of standard circuit breakers corresponding to the nominal power of the PCMDNI300 and for avoiding contact damages at upstream switching equipment, an active inrush current limit with reverse polarity protection is installed in the input circuit of the converter. The series is constantly short-circuit protected and needs no ground load. Further features are SMD-technology, automatic 100 % final test and 100-%-burn-in-test. The converter is connected via industrial plugs optional with screw or spring clamp connectors.
