SD350/800 High-Protection Inverter

The SD Series Sealed Inverters have an ingress protection (IP) rating of IP65 (available by pre-order;  IP55 as standard). They are designed for dust, water, and corrosion resistance, making them suitable for  complex environments such as the chemical, coal mining, and textile industries. As power control equipment specifically engineered for harsh conditions, they feature a sealed structure combined with  high-power waterproof fans and closed-cell foam gaskets—these components ensure effective heat dissipation to prevent damage caused by high temperatures. Additionally, the inverters support multi-speed  control, PID regulation, overload/overvoltage protection, and continuous operation during momentary  power failures.
