REOHM Resistor BW 156 Series

Max. continuous power: 1,500 W

Description

Braking resistor for small to medium power drives with frequency converters. Can be mounted inside and outside the control cabinet.

Advantages

Quick connection
short-circuit proof
Small dimensions with high power
Very good heat dissipation
High-impedance in case of overload
Optional with touch protection and temperature switch
Optional
also for aggressive environments (e.g., salt spray)
Also mountable outside the control cabinet, compact
Also with UL certification, see overview “”UL-Certified Products from REO””

For small resistance values, the conductor cross-section is adapted to the current.

In case of destruction, the resistor becomes high-impedance, therefore each series is available with a temperature switch. The specified power ratings were recorded with the resistors in a horizontal position in the air, with a minimum distance of 100mm to the substrate. The power ratings refer to the standard products with a normal tolerance of +/- 10% at an ambient temperature of 20°C.
