Design - 8200 and 9300 vector
Brake chopper 8253 /9352
m
8253 and 9352 brake choppers can be optimised for the required brake power. For this purpose, the brake choppers are operated with an external brake resistor. The minimum brake resistance is 47 ohms on the 8253 and 18 ohms on the 9352.
The brake chopper can be mounted directly adjacent to three-phase 8200 frequency inverters (8253 for 8211 -18, 9352 for 8241 -46, 8221 -27 and 9321-33EV). If a lower brake power is required, a brake module with an integrated brake resistor can be used.
