    LS Electric iRU Regenerative Unit 400V 7.5-280 kW (Discontinued)

    LS Electric iRU Regenerative Unit 400V 7.5-280 kW (Discontinued)

    The LS Electric Starvert iRU regenerative braking unit (400 V class, 7.5-280 kW, 25% ED), which returns AC drive braking energy to the mains instead of a braking resistor, is discontinued; these codes are offered as replacement spares.

    Key features

    • Replaces braking unit and resistor; regenerates energy to the 380-480 VAC supply
    • Typical use: elevators, hoists and other regenerative loads
    • Braking torque 150% 1 s, 100% 100 s, 35% continuous; 25% ED rating
    • RUNF / RUNS / EST / RST inputs, fault relay and 24 VDC status output
    • Overcurrent, overload and DC overvoltage (approx. 850 VDC) protection
    • "F" models (up to 22 kW) with built-in EMC filter
