SINAMICS Braking resistor 380-480 V 5.5R 120000W PK 5600W cont. 526x 484x 301 mm HxWxD IP20 Braking resistor SINAMICS braking resistor for modular SINAMICS G120 inverters. The braking resistors include an integrated braking chopper and allow high inertia loads to be quickly braked. Excess energy is fed back to the inverter while the load and motor are being braked. This causes the DC link voltage to increase. The inverter transfers the excess energy to an externally mounted braking resistor. The braking resistors are also designed and dimensioned for use with the MICROMASTER 440 inverter series, frame sizes A to F with integrated braking chopper. SINAMICS – simply my drive!
