Brake Transistor
Internal Brake Transistor
All models of the drive have an Internal Brake Transistor (sometimes referred to as a Brake Chopper) fitted as standard that automatically enables when the regenerative energy from the load reaches a pre-determined level as shown below:
Drive Voltage Rating | Brake Transistor Turn-On Voltage | Brake Transistor Turn-Off Voltage |
|---|---|---|
Single and 3 Phase 230V | 390Vdc | 378Vdc |
3 Phase 400V | 780Vdc | 756Vdc |
Note
The brake transistor will ONLY turn on while the drive is running. If the levels are reached while the drive is stopped or inhibited the brake transistor WILL NOT turn on preventing the brake transistor from burning out.
