SINAMICS/ SIMOVERT MASTERDRIVES BRAKING RESISTOR 510-620V DC 170 KW, 2.35 OHM Braking resistor SINAMICS/SIMOVERT braking resistor for SINAMICS and SIMOVERT. Excess energy in the DC link is dissipated via the braking resistors. For generative operation, e.g. braking a mass with a large moment of inertia, a braking resistor must be connected that converts the energy to heat. The heat dissipated from the braking resistor must not adversely affect the cooling of the converter. For this reason, a minimum distance of 150 mm must be maintained between the converter and the braking resistor. The SINAMICS/SIMOVERT Masterdrives braking resistors are available for DC link voltages ranging from 510 V to 780 V and for line voltages ranging from 5 kW to 170 kW, and the SINAMICS/SIMOVERT braking resistors are available for DC link voltages ranging from 510 V to 620 V and for line voltages ranging from 5 kW to 10 kW. SINAMICS – the integrated drive family for every field of application.
