Precise regulation from 1kW to 500kW is achieved through a multi-stage switching combination (1kW to 200kW). Load element tolerance is ±2.5%, ensuring accurate test results.

● Dual-voltage compatible, multi-purpose in one unit: Supports 416Vac / 208Vac dual-voltage input, 50/60Hz universal, suitable for mainstream power distribution systems worldwide.

● Professional power configuration: Rated power 500kW (PF=1.0), resistive load, stable and high-precision testing.

● Fine stepping, flexible control: Supports fine stepping from 1kW with step combinations: 1/2/5/10/20/50/100/200kW, enabling accurate simulation of any load point.

● Strong heat dissipation & wide environmental adapt ability: High air volume 1600 CBM/Min forced horizontal air cooling, operating temperature -25℃ ~ +55℃, stable under extreme working conditions.

● Multiple safety protections: Equipped with thermal emergency cut-out, air flow switch, fan overload protection and emergency stop to fully ensure test safety.
