Design - 8200 and 9300 vector

Brake module 8251 /52

The 8251 and 8252 brake modules are supplied with a built-in brake resistor. The maximum peak brake power is 2.0 kW with a duty cycle of 3% for a maximum of 10 seconds.

The 8251 brake module is for 8201 - 8204 single-phase inverters; the 8252 brake module is for 8211 - 8218 three-phase inverters. If a higher brake power is required, the 8253 brake chopper can be used with an appropriate brake resistor.
