Braking chopper 11-22 kW | TRANSOMIK ® BC1

Principle of operation TRANSOMIK B, BC braking choppers make use of modern MOSFET/IGBT power transistors to switch the braking resistor when the brake voltage-threshold is reached. The connection to the inverter is very simple. Two cables to the DC link are required. An external control voltage is not required. TRANSOMIK B1, B3 braking choppers with integrated braking resistors are especially suitable for applications with high braking powers of short duration. These braking choppers are available for peak braking powers up to 59 kW with a corresponding maximum continuous braking power of 3 kW. The standard setting of the brake-voltage threshold with TRANSOMIK B3 is DC 670 V corresponding to operation with a supply voltage of 3AC 400...415 V +10 %. Other brake-voltage thresholds are available on enquiry.
