Core Product Lineup
Universal Surge Protection Devices (DHO Series)
Full coverage for low-voltage power distribution systems, including DHO 20, DHO 40, DHO 60, DHO 80, and DHO 12.5 (T1+T2). Supports various voltage ratings, high-altitude wind applications, and PV photovoltaic systems up to 1500V DC.
DHE Economy Series (DHE Series)
Cost-effective, high-reliability SPDs (DHE 40 to DHE 40-750) tailored for standard industrial and commercial power distribution applications.
Wind Power Dedicated SPDs (Wind Power Class)
Specially engineered for harsh wind turbine environments, featuring high-voltage tolerance up to 1800V AC/DC (DHO 40-850 / 1140 / 1500 / 1800) to ensure continuous stability under high-vibration and extreme conditions.
Signal & Data Line Surge Protectors (Signal & Data)
Precision surge protection for analog, digital, fieldbus, temperature, video surveillance, and combined power/data lines to shield sensitive control systems from transient overvoltages.
