WJ200-004MF Hitachi HP 3.5A Single Phase 100-120V AC Inverter
The WJ200-004MF is a legacy product and despite still being available it is not recommended for new designs. The WJ200 series has been replaced by the WJ-C1. Upgrading is simplified as the WJ-C1 has the same footprint, and parameters can be copied from the WJ200 to the WJ-C1.
The WJ200-004MF is a HP variable speed drive from the Hitachi WJ200 series, with a rated output of 3.5A for constant torque applications running from a 100-120V AC Single Phase supply. The WJ200-004MF can also be used with a HP or 3.5A motor in variable torque application such as centrifugal fans and pumps.
The WJ200-004MF features advanced sensorless vector control with a high starting torque of up to 200% and dramatically improved speed stability. A brake chopper 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 reducing external components by utilizing features such as the safe-stop and Easy Sequence (EzSQ) which allows PLC like functionality.
The WJ200-004MF is capable of driving permanent magnet (PMAC) motors as well as standard induction motors.
The WJ200 is low maintenance by design, with DC bus capacitors and cooling 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 others as master or slave.
