Product code: OD-BR100-IN / OD-BRES4-IN / OPT-BR050-IN-I55
Dynamic Braking Resistors
Optidrive Size 2 to 6
Optibrake dynamic braking resistors are
designed specifically for the Optidrive range.
For use with high inertia loads which need to
be stopped rapidly, Optibrake dynamic braking
resistors assist the Optidrive manage the
electrical energy returned from the motor
during braking, by converting it to heat energy.
Key Benefits
- Optidrive software protects the Optibrake from overload,
hence no need for expensive overload relays are required
- Internal fusible element ensures fail safe operation
- Connects to side of drive, using heatsinking properties
of heatsink to prevent overheating
- No space envelope penalty, fits on side of drive
- Serial parallel arrangements for more demanding applications
Key Physical Features
- Robust assembly
- Wirewound
- Metal clad housing
- Internal fuse link protection
