AC/DC Industrial Power Converters

The primary switched AC/DC modules (AC/DC Industrial Power Converters) series PMAS/PCMAS have been designed as a universal compact power supply with AC and DC wide input ranges for worldwide application and allow an efficient, cost-saving solution for different tasks where low and medium power is needed.

These modules are available as a standard with single, dual or triple outputs in different power ranges with 5 to 100 W and as special power supplies. The power supplies are vacuum encapsulated, prepared for applications in Class 1 and/or 2 and comply with the Low Voltage Directives as well as the up-to-date EN standards as regards CE conformity. Further features are rugged design, SMD-technology, automatic 100 % final test and 100-%-burn-in-test.

AC/DC Industrial Power Converters are UL and cUL approved. The series are short circuit protected, need no ground load and are designed for PCB (PMAS) or chassis mounting (PCMAS).

AC/DC Power Supply Modules

With the series PMAT/PCMAT60, MTM Power® expands its program with the third generation of AC/DC modules for reliable supply of electrical and electronic systems. The 60 W modules (ac-dc power supply modules)are electrically and mechanically compatible to the PMAS/PCMAS48 series and thus offer 25 % more output power in the same case. The typical efficiency of Industrial power supply modules is up to 89 %.

The thermoselective vacuum encapsulation is a reliable protection against mechanical stresses and environmental conditions like humidity and conductive dust. The ac-dc power supply modules are optionally available for PCB mounting (PMAT) or for chassis mounting (PCMAT) with screw connectors. The wide input voltage range of 85…264 VAC enables the worldwide use at AC voltage grids. As an option, an active inrush current limiting is available which is particularly advantageous when operating several modules at only one control circuit. On the output side, stabilised voltage of 24 VDC is provided; other output voltages are available on request.

AC/DC Modules Resistant to Dust and Moisture

Following the state-of-the-art trend in automation for decentralized systems without cabinets has designed the series PM-IP67A with 50, 75, 100, 150 and 200 W. Remarkable feature of the primary switched modules is that they (AC / DC modules resistant to dust and moisture) are suitable for applications with protection degree IP67 for different tasks in indoor and outdoor industrial applications.

Without any additional protection against harsh environmental conditions these power supplies can be mounted and used just at the place where needed. Due to the disuse of cabinets or cases for the installation of the power supplies, they allow an efficient, cost-saving solution for different tasks. The compact power supplies with AC and DC wide input range are available with single and dual outputs and connected via 7/8" connectors. AC / DC modules resistant to dust and moisture are vacuum encapsulated, acc. to Protection Class 2 and comply with the Low Voltage Directives as well as with the up-to-date EMC Standards as regards CE Conformity.

Railway DC DC Power Converters

This vacuum encapsulated Railway DC DC Power Converters series PMDS/PCMDS30 are especially designed as decentralised power supply for industrial applications and railway vehicles. These 30 W Railway DC DC Power Converters operate according to the current source push-pull principle and working with a frequency of 70/140 kHz.

Advantages of this switching topology are the wide input voltages with constant efficiency, transformer with good coupling and low leakage inductance, at the same time usable for direct control of the secondary synchronously detection. The PMDS/PCMDS30 cover an input voltage of 14.4…154 VDC with only two different nominal voltages (24/110 VDC). They are available with output voltages of 5.1, 12, 24 or 48 VDC.

Further features are reverse polarity protection in connection with an active input current limiting. Depending on the application the converters are available either for print (110 x 80 x 27,5 mm) or chassis mounting (110 x 80 x 25,5 mm).

Industrial DC-DC Converters

Compact, encapsulated Industrial DC-DC Converters with 60 W, 80 W and 150 W output power are designed for vehicle and rail technology, as well as industrial and telecommunications sectors. They operate according to the push-pull principle; i.e. the input dc-voltage is chopped by two push-pull working transistors with a frequency of approximately 70kHz. With the help of a transformer and a secondary linear choke, a galvanically isolated output voltage of 5 V – 48 V is produced which is adjusted by pulse-width modulation according to the current mode principle. The converters are available with a wide input range for battery voltages of 24, 36, 48, 60, 72, 80, 96 and 110 V. They need no ground load and are short-circuit protected by primary and secondary power limiting. The thermoselective vacuum encapsulation guarantees homogeneous heat dissipation in addition to high resistance to environmental factors including shock, vibration and humidity.
