Product description

DC/DC transformers allow the safe operation of consumers with voltage rates that are differing from the board voltage in the vehicle. For instance, many products of the information, entertainment or navigation technology are almost exclusively only available in 12V technology. Then, an operation with 24V board mains supply is possible by means of a suitable DC/DC transformer from 24V to 12V, without requiring to install an own 12V battery circuit.

The galvanic isolation between input and output of the units by separation of the ground paths effects an outstanding interference suppression (filtering). Even in case of long connection cables, perfect ground ratios being independent of each other are ensured on both sides, which is advisable for large vehicles, containers, roll containers, trailers etc.

Galvanisch isoliert ENBesides, the galvanic isolation also ensures absolute protection against 24 V / 12 V punctures, as well as overvoltage in case of loss of mass. Inrush current, peak current or starting current of the consumers are compensated by the short-time 30 % overload capacity of the transformers. One of three stable output voltages can be adjusted at the output, see table. The adjusted voltage is kept stable under most different conditions.

Activation of the transformers is effected by a control signal, either manually by means of the ON/Off-switch, or automatically by means of the vehicle's ignition or signal D+ with activated generator. A further possibility is the automatic control by the operating voltage, which is advisable, if a further control signal is not at disposal. The function can be adjusted in 4 stages. A combined control by means of signal and voltage also covers special cases, such as the DC/DC transformer will only become active, if the starter battery had been charged to a certain minimum, if a battery discharge shall be avoided etc.
