MTM Power offers 150W power supplies for use in railway applications

Installed as a decentralised power supply for industrial and railway applications, the PCMAT150 S24, is a range of AC/DC modules from MTM Power.

They are available in a wide AC/DC (90 to 264V AC) input range for use in industrial networks worldwide and a 12 or 24V DC output voltage is generated.

The contact-cooled devices have a power good signal as well as an active power factor correction (PFC). The operating temperature range is -40 to +70 degrees C, remote control and 150 per cent power boost, claims MTM.

The supply can be used in applications with high transients as, for example, energy technology, by virtue of the isolation co-ordination to overvoltage category OV 3.

For use on rail vehicles, the devices were tested according to the standards of EN 50 155 and EN 50 121-3-2 / EN 50 121-4. In compliance with the conditions of the railway regulations the units can be used on railway vehicles on the 400/230V AC internal on-board train power system, in track-side applications and in stationary railway systems.

The PCMAT150 has an efficiency of 92.5 per cent and is resistant against shock and vibration due to the well-proven encapsulation technology and its extremely rugged design.

The vacuum encapsulated (EP 1 987 708, U.S. Patent No. 8,821,778 B2) power supplies offer reliable protection against condensation, conductive dust and other environmental conditions. They are connected via industrial connectors which meet the demands concerning vibration resistance, reduced wiring time and being maintenance-free in sensitive electronic sub-systems. The rugged design is claimed to dissipate the thermal losses via the mounting plate while increasing the life-time of the devices.
