Hitachi Variable Frequency Drives — Japanese Reliability for Industrial Automation

Hitachi is a Japanese corporation with more than 110 years of history and one of the world's leading manufacturers of industrial electronics and automation equipment. Hitachi VFDs are used in metalworking, food processing, pump and ventilation systems, conveyor lines, and textile production. Visit our variable frequency drives catalogue for the full range — from compact single-phase models to high-power industrial drives.

Hitachi VFD Product Lineup

Hitachi offers four VFD series, each targeting a specific application profile:

Series Power Range Supply Key Features Typical Applications
WJ200 0.4–15 kW 1×220 V / 3×380 V Sensorless vector control, built-in PLC, IP20, mini-USB port Conveyors, pumps, fans, gate operators
WL200 0.2–18.5 kW 1×220 V / 3×380 V Vector control, built-in EMC filter, IP20 EMC-sensitive environments, industrial networks
SJ700 0.7–400 kW 3×380 V Sensor and sensorless vector control, built-in PLC (B-series), EMC filter (B-series), IP20 (B-series) Heavy industrial machinery, high-load drives
NES1 0.2–4.0 kW 1×220 V / 3×380 V V/F (scalar) control, compact housing Low-power equipment, small commercial applications

How to Choose a Hitachi VFD

To select the right model, determine your motor power, supply type, and required control precision. The WJ200 series suits most standard applications — it combines vector control with a built-in PLC in a compact form factor. The WL200 series is the choice where strict EMC requirements apply: the built-in EMC filter eliminates the need for external components. The SJ700 series handles heavy loads from 0.7 to 400 kW; the SJ700B variant adds IP20, EMC filter, and built-in PLC. The NES1 series is the most affordable option for scalar control of small motors.

Hitachi WJ200 and SJ700: when to pick a Japanese drive over a Chinese one

Hitachi is what customers come back for after a cheap Asian drive let them down. Over the past 12 months we mostly shipped WJ200 (5.5 and 7.5 kW) for mine pumps and equipment with frequent restarts after long idle periods, where IGBT lifecycle matters. NES1 at 2.2 kW moves slower. This is not a mass brand for serial installations: it is a niche pick for specific jobs.

The catalogue covers four series: NES1 up to 4 kW (entry-level), WJ200 up to 15 kW (the workhorse), SJ700 up to 160 kW (flagship with closed-loop vector control), plus one WL200 SKU. For a standard pump or fan we usually propose Delta VFD-E instead: lower price, faster Kyiv-based repair. Take Hitachi when Japanese build quality matters and you need 50,000+ hours of continuous-duty service.

Hitachi VFD Series

NES1 — Compact Series for Low Power

7 models, 0.75–4 kW. Compact budget drive for simple general-purpose tasks. Basic functionality, easy integration.

WL200 — Specialised Application Series

1 model, 2.2 kW. Drive with extended functions for specific industrial applications.

WJ200 — General-Purpose Industrial Series

12 models, 0.75–15 kW. Sensorless vector control, Modbus RTU. Conveyors, pumps, fans, machine tools. Reliable and cost-effective for serial OEM projects.

SJ700 — Flagship Industrial Series

31 models, 0.75–160 kW. Vector control with and without encoder, 150–200% overload, CC-Link, Profibus DP, DeviceNet. For cranes, conveyors, compressors, and complex production equipment.

Which Hitachi Series to Choose?

Simple mechanism up to 4 kW — NES1. Conveyor or machine tool up to 15 kW — WJ200. Crane, compressor, or high-power production equipment up to 160 kW — SJ700.
