-
-
Functional Features:
-
4-Quadrant Operation: Handles motoring and regenerative braking efficiently.
-
Integrated Braking: Built-in ballast circuit and resistor, no external shunt resistor strictly required for light regen.
-
Monitoring: LED indicators for over/under voltage and thermal status.
-
Commutation: Trapezoidal (6-step) commutation logic.
-
-
Material & Structural Features:
-
Form Factor: Compact Eurocard dual-board design for 19-inch racks.
-
Cooling: Forced ventilation (Fan assisted, critical for 12A continuous rating).
