Offering high safety and high quality specifications, MTM power modules are the perfect solution for Railway Applications, E-mobility, Transport, Special Vehicles, Wind Energy, The Telecom Industry, Power Plants, The Chemical Industry, Industrial Robots, Programmable Logic Controls, and Safety-conscious Areas (e.g. Petrochemical Drilling Platforms). With an in-house R&D department, MTM's own EMC laboratory, and state-of-the-art technical equipment, MTM Power can assist with all your design requirements.
MTM Power GmbH, the specialist for individual power supplies, offers in its extensive program of standard industrial converters a type in a DIL 24 case with an output power of 5 to 6 watts. Outstanding feature is the isolation voltage of 6,0 kV.
Besides their compact design the PMD5UD-6kV converters are characterised by a 4:1 ultra wide input range. The PMD5UD-6kV is available with a nominal input voltage of 24VDC (9…36VDC) or 48VDC (18…72VDC) and output voltages of 5V, 12V or ±12V, ±15V. They are working at a temperature range of -40…+71°C and the transient response time is <500μs. They have a high efficiency up to 85% and are built in a non-conductive black plastic case.
Further technical features are low ripple & noise, an internal input π-filter, undervoltage lockout and continuous short circuit protection.
For use in different industrial applications, but also for the sophisticated use in the vehicle and railway technology, MTM Power® for the first time introduces with the series PCMAT150 a generation of AC/DC modules with Base Plate Cooling Technology.
Based on the PCMDS150, especially designed and already well-proven for applications in vehicle and railway technology, MTM Power offers now a 24 Vout version as a 19" plug-in unit.
A special feature of the PCMDS19 150 is the connector on the front plate where both input and output voltage can be connected. This connector is of course suitable for railway applications. The converter is available with a wide input range of 50,4…154 VDC for the battery voltage of 110 VDC acc. to EN 50 155 and an isolation of 2.2 kVAC. The dimensions are 178.5 x 70.8 x 128.4 mm (length x wide x height).
The thermoselective vacuum encapsulation (EP 1 987 708, U.S. Patent No. 8,821,778 B2) guarantees uniform heat dissipation within the module as well as excellent resistance against environmental influences such as shock, vibration and humidity. In addition, the converter is cooled via the installed heat sink.
The device needs no ground load and is short-circuit protected by primary and secondary power limiting. The maintenance-free converter can be operated in parallel, is prepared for the use in devices with protection class II and can be switched into an energy-saving stand-by operation mode by a remote control input. It shows a mechanically and electrically rugged design using SMD technology and undergoes an automatic piece-by-piece test.
The DC/DC converters PCMDS80 from MTM Power® are specially designed as decentralised power supplies in vehicles and for supplying closed sub-systems in rolling stock applications. They are available with three wide input ranges thus enables the use of the converters on batteries with 24 to 100V acc. EN 50 155. The converters are also suitable for use in industrial and telecommunication applications.
The PCMDS80 are available with 80 W output power and operate according to the single transistor forward converter topology with a frequency of 50 kHz. With the help of a transformer and a secondary linear choke, a galvanically isolated output voltage (12V; 13.8V; 24V; 27.6V or 48V) is produced which is adjusted by pulse-width modulation according to the current mode principle. The devices can be operated in a temperature range of -4o to +70°C without derating and have an efficiency of up to 88%.
The dimensions of the base plate version are 119 x 100 x 40 mm. Due to the rugged design with contact-cooling (BPC technology), it is possible to reduce the power loss via heat dissipation through the mounting plate while increasing the life-time of the devices at the same time. In addition a heat sink version with 119 x 115 x 65 mm (length x width x height) is available. The thermoselective vacuum encapsulation (EP 1 987 708, U.S. Patent No. 8,821,778 B2) guarantees homogeneous heat dissipation within the modules as well as an excellent resistance against environmental influences such as shock, vibration and humidity. The converters need no ground load and are short-circuit protected by primary and secondary power limiting. They are maintenance-free, prepared for the use in devices with Protection Class II and fulfil the fire protection directive EN 45 545-2.
With patented thermoselective vacuum encapsulation and IP65 sealing, MTM Power’s PCMDS150WK-IP65 DC-DC converter provides rugged reliability in rail applications. Wide input voltage ranges, covering rail inputs from 24 to 110VDC, and a galvanically isolated 24V output are combined with a power rating of 150W and high efficiency.
Customisation of the standard converter can include adaptations to meet specific mechanical, electrical or environmental parameters for individual rail projects.
MTM Power® GmbH, the specialist for high quality power supplies, offers in its program the DC/DC converters series URC for rail applications. They have been designed as power supplies for the use in vehicles, particularly for railway applications. The series is available with both 50 W & 75 W. Due to the ultra wide input range of 12,5…154,0vDC, the converters can be operated at all usual battery voltages (24/36/48/60/72/110 VDC) acc. to EN 50 155 in railway vehicles and in stationary applications. They are available with the single outputs 5,1VDC, 12 VDC and 24VDC. The converters can be used as a 19" plug-in or for wall mounting both to be connected via a H15 connector and can be switched on and off by the enable input. Further features of the URC series are input and output voltage monitoring, high temperature range, high reliability and long life.
