Hitachi SJ100 inverter

The Hitachi SJ100 series of VSD Variable frequency drive is a small low cost inverter suitable for standard AC motors.

We carry the full range from stock and can typically offer good lead times on any that are out of stock.

The SJ100 has been superceded a number of times, the current equivalent is the Hitachi WJ200. If you have specific requirements we can help you to select a solution.

We do have some stock available, contact us for availability and current pricing. We can also offer repair estimates and servicing.
