WJ200-004LF Hitachi 0.75HP 3A Three Phase 200-240V Inverter
The WJ200-004LF is a legacy product and although still available it is not recommended for new designs. The WJ200 series has been superceded by the WJ-C1. Retrofitting is simplified as the WJ-C1 has the same footprint, and settings can be copied from the WJ200 to the WJ-C1.
The WJ200-004LF is a 0.75HP variable speed drive from the Hitachi WJ200 range, with a rated output current of 3A for constant torque applications running from a 200-240V Three Phase supply. The WJ200-004LF can also be used with a 0.5HP or 3.5A motor in variable torque application such as centrifugal fans and pumps.
The WJ200-004LF features advanced sensorless vector control with a high starting torque of up to 200% and dramatically improved speed stability. A dynamic braking transistor is included as standard in all models as is the integral keypad, although an enhanced keypad or programming using the built in USB interface is also available.
Side by side mounting is possible to save panel space, and further space and cost savings can be achieved removing external components by utilizing features such as the safe-stop and Easy Sequence (EzSQ) which allows PLC like functionality.
The WJ200-004LF is capable of driving permanent magnet (PMAC) motors as well as standard induction motors.
The WJ200 is designed to be low maintenance, with DC bus capacitors and fans having a design lifetime of 10 years, and screwless spring loaded terminals don't just make installation simple, they also don't need retightening during service.
Modbus communication is built in as standard, however option cards can add a variety of different fieldbus protocols, along with EzCom peer to peer communications between drives being possible, with 1 drive acting as administrator and the remaining drives as master or slave.
