TRV resistors are high power, forced air cooled resistors, suitable to be used in harsh environments. Protection degree is IP65 / IP66. The power ranges from 50 – 275 kW. TRV units are fitted with 2 or with 4 strong ventilators to cool the resistor elements. The unit can be as a single resistor group or with multiple groups, in various electrical topologies. Applications are brake resistors on cranes in harbor or deck winches.
