PSUs for industrial and railway use

21 March 2018 Power Electronics / Power Management

With the PCMAT150 S24, MTM Power has introduced a new generation of AC-DC modules which can be installed as a decentralised power supply for industrial and railway applications.

From wide AC (85 – 264 V) or DC (100 – 300 V) input ranges for worldwide use in industrial networks, a 24 V d.c. output voltage is generated. The contact-cooled devices have a power-good signal as well as active power factor correction. Further features are an operating temperature of -40°C to +70°C, remote control and 150% power boost.

The design of the isolation system according to over-voltage category OV 3 enables use in applications with high transients, such as in energy technology. For use on rail vehicles, the devices were tested according to the standards of EN 50155 and EN 50121-3-2/EN 50121-4. In compliance with the conditions of the railway regulations, the units can be used on railway vehicles on the 400/230 V a.c. internal on-board train power system, in track-side applications and in stationary railway systems.

The PCMAT150 has an efficiency of 92,5% and is resistant against shock and vibration due to the well-proven encapsulation technology and its extremely rugged design. The vacuum encapsulated 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, and thus their use as a plug-and-play solution in sensitive electronic sub-systems is possible. Due to the rugged design in BPC technology, the thermal losses are dissipated specifically via the mounting plate while increasing the lifetime of the devices at the same time.
