DC-DC power supplies

16 March 2011 Power Electronics / Power Management

The DC/DC power supply systems of the series MPG from MTM Power are designed among others or supply of electrical applications from DC mains for different applications in transportation, telecommunications and the charging of lead batteries during standby parallel operation.

The universally usable, modular and scalable system is based on the DC/DC converters of the series PCMD250W and PCMD400W which are proved in transportation applications. The series is available with two to five plug-in positions (MPG2, MPG3, MPG4, MPG5) for the 250 W or 400 W converters and a total output power of 500 to 2000 W. With different input voltage ranges between 14,4 and 154 V d.c., the devices supply output voltages between 12 and 110 V d.c. The output voltage operates with IU characteristic curve and the system can be switched into an energy-saving standby mode via a remote control input.

Further features include signalling of input and output voltage by an LED as well as a potential-free power good signal. The whole system is passively cooled by convection and is designed for an ambient temperature range of -40°C to +70°C.
