IP66-rugged frequency inverter built for dust, water jets and harsh conditions
The EP66 series is a high-protection-grade frequency inverter built for the harshest environments. With rugged IP66/NEMA 4 construction compliant with EN 60529, the drive is completely dust-tight and fully protected against jets of water and heavy waves — allowing wall-mounted, cabinet-free installation in locations where ordinary inverters cannot survive. A removable cable conduit plate with humidity-barrier vent keeps moisture out, while polycarbonate (≤15 kW) and metal (18.5–90 kW) housings deliver durable, corrosion-resistant performance from 0.4 kW to 90 kW.
At its heart, a DSP-based motor control platform supports V/F control, sensorless vector control and PMSM sensorless vector control in speed or torque modes, delivering 150% starting torque at just 0.5 Hz, a 1:100 speed control range and ±0.5% steady-state speed precision. Intelligent autotuning makes setup quick, and all standard inverter functions are built in — 15-stage speed control, built-in PID, auto voltage regulation, DC braking, speed-track starting and jog control.
Designed for real-world convenience, the EP66 offers space inside the drive for customer options such as a main/emergency switch, start/stop selectors, a potentiometer and a brake resistor, plus an optional built-in bypass switch. A C3-class EMC filter is standard. Smart PC tools support control and troubleshooting, and configurable LCD keypads are remote-mountable via waterproof connector. CE and UL certifications make it ready for the worldwide market.
