REOhm series R 157
Max. continous power: 300 W
Descripción
High voltage resistor for drives with frequency converters of small to medium output,
installation close to the frequency converter. They are used to damp over-voltages or to
dissipate excess energy that originates, for example, on braking or starting up. This is done by
converting the electrical energy into heat in the resistor.
Punto de venta único
Due to their special application, these resistors are are subject to special requirements. Highest
reliability and durability combined with an extreme resistance to adverse environmental
impacts are therefore absolutely necessary.
small dimensions
fast connection
short-circuit proof
matching to any frequency converter
less additional mounting space required
Protection ratings IP 20 / IP 40 / IP 54
Higher IP ratings upon request
Test voltage: 10,5 kV DC und 8,3 kV AC
Other ratings and fastening dimensions upon request
very compact construction
high resistance in case of overload
vertical and horizontal design
