The JL/X series AC Drive is a fully digital drive system providing 45kW – 975kW output power to control AC slip ring motors. The JL/X is designed for retrofit applications on cranes, material handling, hoists, pumps, compressors & conveyors.
Available in 2Q (single direction) and 4Q (fully regenerative) variants, the range comprises 3 compact chassis sizes with models rated at 150% overload (standard) or 250% overload (high duty). The JL/X boasts an extremely versatile operating input voltage range of 12V – 500VAC as standard. Options are available for 600V and 690VAC input.
All models include a 40-character alphanumeric backlit display that makes it easier to quickly navigate through an extensive range of software functions.
IDEAL UPGRADE FOR CRANES & HOISTS
Upgrading your AC-slip ring motor application usually involves replacing the motor with a new motor and drive combination (expensive), or modifying the existing motor to allow a retrofit standard AC Drive. For users wishing to maintain the high starting torque of AC slip ring motors, you can simply bolt on the JL/X AC Slip-Ring Drive, which is designed to work seamlessly with AC slip ring motors. The JL/X provides full digital control and maintains the classic torque-speed curve so critical for lifting applications.
