2. Features:

Non-contact, CPU intelligent SCR control, Digital Circuit Control, stable and reliable
High efficiency：>99%。
High precision ：±1%,2%, ±3%, ±5% (adjustable)
Non-contact、anti-interrupt、maintenance free、no mechanical failure and carbon brush attrition.
Intelligent instrument display: intelligent instrument real-time display of voltage, current, power, such as RMS, clear, accurate, high resolution, thin-film button operation, safe and reliable.
Three-phase separately adjustment：Output voltage unbalance is less than 1% so that guarantee the precision of each phase is stable.
Wide application range: Widen voltage stable range, it can meet the need to work in the poor voltage condition
Quickly response: stabilization response within 40mm, no influence on computerized automation, Machine and Equipment.
Full protection function: fault display and alert in over loaded, over voltage, lack of voltage, lack of phase, short circuit, over heat, confirming appliance running in a safety condition.
Preset function: Protective limit can set freely.
Strong ability for instantaneous overload: The high quality material can confirm excellent performance. This machine can continuously run in 100% rated load. Further more, it can bear the instantaneous overload without any harmfulness.
