TND(SVC) (0.5–30kVA) and TNS(SVC) (1.5–60kVA) use servo-motor driven contact regulators for high-accuracy (±3%) general commercial and laboratory use. SBW (30–1000kVA) provides heavy-duty high-power compensation with ≥98% efficiency. DJW (10–100kVA) & SJW (10–1000kVA) combine microcomputer control with SCR non-contact thyristor switching—eliminating carbon brush wear and mechanical failure while delivering 0.2–0.5s ultra-fast response and three-phase automatic balance.

Specify the Online Intelligent Soft Starter / Cabinet (5.5kW–630kW) when operating in harsh industrial environments with dust, smoke, sand, or ash, or where simplified 3-wire in (ABC) / 3-wire out (UVW) contactless operation without an external AC bypass contactor is preferred (also supports low-voltage starting ≥320V). Specify the Bypass Type Intelligent Soft Starter / Cabinet (5.5kW–630kW) when minimizing continuous thermal dissipation inside enclosed switchgear rooms is the priority—once the motor reaches full speed (Ue=100%), it transfers load to an AC bypass contactor (KM) while maintaining 12 built-in motor protections, RS485 Modbus communication, and DC 4–20mA output.
