II. Product Introduction

With the main body unchanged, the weight is only 10 kg. It adopts stainless steel or plastic-aluminum case, which is beautiful, sturdy, and has good shock absorption performance. It uses a dual carbon brush voltage regulator (i.e., double-sided voltage regulator). The large knob adjusts AC/DC voltage and current with heavier loads, while the small knob adjusts AC/DC voltage and current with lighter loads.

It can output two channels simultaneously. It adopts 0.5 class digital meters and high-precision sensors for accurate measurement. It uses a six-digit digital electric stopwatch to meet time measurement requirements. It is truly a good tool for relay protection personnel working outdoors.
