With the PCMAT100 S24, MTM Power introduces a new generation of AC/DC modules which can be installed as a decentralised power supply for industrial applications. As industrial compact power supply with wide input range (90 to 264VAC), the 100W module is designed for direct connection to the main power supply network and certified in acc. to DIN EN 62 368-1 / UL 62 368.

The design of the insulation coordination to the requirements of the overvoltage category OV3 allows the use in applications with transients, such as the electric engineering.

With appropriate thermal connection and contact cooling via the base plate, a 24VDC constant voltage is generated without dearting in the working temperature range of -40 to + 70°C. Due to the rugged design in BPC technology, the thermal losses are dissipated specifically via the mounting plate while increasing the life-time of the devices at the same time. The circuit concept used is easily modifiable, so that further output voltages are relatively easy to realise if required.

The PCMAT100 has an efficiency of 90% 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 and thus the use as a plug-and-play solution in sensitive electronic sub-systems is possible.
