I. Overview
1.Use
HZDL-200III high current generator (referred to as three-phase current booster) is a test equipment developed by our company. It integrates the advantages of similar products at home and abroad. It adopts numerical control technology and has strong anti-interference ability. Compared with the converter, the converter has the advantages of large output power, small size and light weight due to the use of low power consumption, large capacity self-coupling voltage regulator and high magnetic permeability iron core. Mainly used for thermal relay, motor protector, contactor, circuit breaker, air switch, switch cabinet, circuit breaker, protection screen calibration.
2.Features
◆ Using beautiful and elegant PVC panel
◆ Display the primary current directly, which is convenient for test observation and recording.
◆ High measurement accuracy: 0.5 class
◆ High power, small size and strong load capacity
◆ Small size and light weight, the volume is only 30% to 70% of similar products, and it is very convenient to move.
