MTM Power has expanded its range of DC/DC converters with a new series that is tailor-made to meet the requirements in vehicle technology.

Highest quality and safety are of particular importance when using power supplies in these applications. As a link between the supply system and the electronic subsystems, extremely high demands are placed on them with regard to their reliability. Due to the good price performance ratio and the excellent technical data, these converters, though, are increasingly used in stationary and industrial applications.

The new PMDS200-FT series can be flexibly used. The nominal input voltages are 48 V and 80 V. The existing input filter protects the devices against the typical transients occurring inmon-board electrical systems. The standard output voltages are 12 V and 24 V. Other voltages, e.g. end-of-charge voltages for lead-acid batteries can be realised on request.

The low Ripple & Noise values combined with a high output voltage constant guarantee reliable operation of all connected consumers. Other decisive features are short-circuit resistance, transient protection, the insulation resistance of 1.18 kVAC prim.-sec. and a wide temperature range -35 ... 70°C (85°C on request).

The PMDS200-FT are designed in a plastic case with an aluminum base plate. They show a compact design (145 x 115 x 38 mm). The thermal concept of these vacuum encapsulated DC/DC converters provides an optimised heat dissipation of all power semiconductors by thermal coupling to the base plate. The encapsulated design allows installation on vehicles without suspension or without pneumatic tires with the highest shock and vibration stresses. The connection is made by cable, suitable plugs can be attached on customer request. The devices are CE-compliant and prepared for protection class 2.
