WJ200-075LF Hitachi 10HP 33A Three Phase 200-240V Inverter
The WJ200-075LF is a legacy product and despite still being 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 The WJ200 series has been superceded by the WJ-C1.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 WJ200-075LF is a 10HP variable speed drive from the Hitachi WJ200 series, with a rated output of 33A for constant torque applications running from a 200-240V Three Phase supply. The WJ200-075LF can also be used with a 15HP or 40A motor in variable torque application such as centrifugal fans and pumps.
The WJ200 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 reducing external equipment by utilizing features such as the safe-stop and Easy Sequence (EzSQ) which allows PLC like functionality.
The WJ200-075LF is capable of driving both standard induction motors and permanent magnet (PMAC) motors.
The WJ200 is designed to be low maintenance, 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 included as standard, however optional communication 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.
