150W Power Supplies for Use in Railway Applications

MTM Power®‘s advanced AC/DC modules have been released with the introduction of the new PCMAT150 S24, as a decentralised power supply that can be used in railway and industry solutions.

From wide AC/DC (85-264 VAC) and DC/DC (100-300 VDC) input ranges for the worldwide use in industrial networks, a 24 VDC output voltage is generated. The contact-cooled devices have a power good signal as well as an active PFC.

Further features include an operating temperature of -40°C to 70°C, remote control and 150% power boost.

The design of the isolation coordination according to overvoltage category OV 3 enables the use of applications with high transients such as energy technology.

For use on rail vehicles, the devices were tested according to EN 50155 and EN 50121-3-2/EN 50121-4 standards.

In compliance with the conditions of the railway regulations, the units can be used on railway vehicles on the 400/230 VAC 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 to 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 to industrial connectors which meet the demands of vibration resistance, reduced wiring time and being maintenance-free and thus the use of a plug-and-play solution in sensitive electronic sub-systems is possible.

From its rugged design in BPC technology, thermal losses are dissipated specifically via the mounting plate while increasing the lifetime of the devices at the same time.
