The DB0.75-4C is the 10%ED type braking resistor matched to the FRENIC-Mini (C2) inverter types listed below. It connects to terminals P(+) and DB on the inverter, which drives it from the built-in braking transistor. Maximum braking torque is 150% for every listed pairing.
Best for
- High-inertia loads that have to stop faster than a coast to stop
- Vertical or overhauling loads that push energy back into the drive
- Short repetitive cycles within the listed duty cycle
Key features
10%ED duty type
Rated for repetitive braking on a 100 second or less cycle at the duty cycle listed for each inverter pairing.
Matched resistance
200 ohm, one unit per inverter, for the inverter types listed below.
Direct terminal connection
Wires to the P(+) and DB terminals provided for an external braking resistor on the inverter.
