Embedded Ultra-Wide Range PSU for Modular Computer Systems

Manufacturer: duagon MEN

The MP1 is a PSU module for use in transportation, e.g., in trains. The power input allows an operating input voltage range from 24 V DC to 110 V DC nominal, which is EN 50155 compliant.

Modular System for Easy Configuration

Due to MEN's modular concept, the MP1 offers flexibility in built-to-order configurations. The PSU can be easily combined with the pre-fabricated CPU module MC50M, providing short delivery times. In the modular system, the data transfer between the modules as well as the power supply of the individual components takes place via the extension connectors standardized by MEN.

Flexible System Installation

Various mounting options facilitate the integration of the module into an existing environment. The standard 35 mm DIN Rail mounting offers space-saving mounting of all system modules on a single rail. Wall mounting and mounting in a 19" rack using adaption brackets are an option.

The aluminium housing with cooling fins provides conduction cooling for fanless operation. MP1 has no moving parts, making it maintenance-free.

In-Vehicle Qualified and Long-Term Availability

The MP1 is qualified for rolling stock. Long term availability of 15 years from product start minimizes lifecycle management by making the MP1 available at least for this period of time.
