1） compact construction form in a rectangular profile
2） short-circuit proof
4） degree of protection IP 40
5） higher continuous dissipation by mounting directly onto heat sink or cooling surface
By mounting directly onto an appropriate cooling surface or onto a heat sink the continuous dissipation can be increased resp. the surface temperature can be lowered.
Typical factors for an increase are 1,5 up to 5, depending on type,ventilation and size of the cooling surface or heat sink.
This type can be fitted with a 180°C temperature switch for monitoring, which has 2 connection wires.
Type designation would be: G.ADQ …
Different applications derive from the various dimensions in width, height and length. We provide e.g. 4 different constructions forms for 155 W.
An important application is the use as braking resistor for motor/generator drive of motors with frequency converters. Because of their degree of protection the resistors can perfectly be integrated into frequency converters or switch cabinets.
