Inverter Braking Resistors (Non-Heavy Duty)

High-quality wire resistors inserted in aluminum enclosure with IP54 (ROF Series) or galvanized steel and IP20 protection (ROPPE Series).
Specifically made to be integrated into command and control equipment for motors, inverters, etc.
Ideal mounting is in contact with the inverter heatsink or a metal cabinet wall that ensures maximum performance in terms of resistor power dissipation.
The special shape and construction allows the use of the maximum amount of active part, thus giving the possibility of absorbing a large amount of energy by adiabatic pulses and at the same time achieving a high power rating.
They are made of non-combustible materials and the winding is embedded in a concrete mass with high thermal conductivity (ROF series), high insulation and complete insensitivity to moisture.
