 Rated voltage

Phase voltage 220V,Line voltage 380V          (Other voltage can also be set, such as: 400V, etc.) 

 Voltage accuracy

±(1-5)% can be selected(the conventional set is ±2.5%,other models are determined according to the model)

 Response time

Fast

 Wave distortion

No additional distortion (static)

Efficiency

≥98%

Three-phase unbalance degree 

Automatic balance of three phase voltage

 Delay output

Voltage regulating before output

(keep devices from impact)

Protect

Overvoltage

Cut off output,turn to bypass uninterruptedly or no action if The output phase voltage is more than 10% (245V),All can be set.

Undervoltage

Cut off output,turn to bypass uninterruptedly or no action if The output phase voltage is less than 10% (195V),All can be set.

Phase lack

Possess(Cut off automatically)

Phase sequence error

Digital phase detection technique, accurately and reliably, effectively avoid misoperation problems caused by harmonic interference.

Overload

Electronic test, Cut off output or turn to bypass uninterruptedly if overload for 3 minutes.All can be set.

Overcurrent

Electronic test and breaker protection

Short circuit

Electronic test and breaker protection

Bypass

Bypass uninterruptedly and automatically

Indicate

current

A,B,C,ΣABC with TRMS resperately on LCD

Working condition

Regulating voltage state / City electric state

Abnormal

Overvoltage,undervoltage,overload, blown fuse,phase lack,phase error

Human-machine interface

Intelligent man-machine interface operation panel, easy to set and query parameters

Overload capacity

5 times the rated current for 1 second

Working mode

Regulating voltage state & City electric state

Quick response

12 bit AD collecting,64 points collecting each wave period,PLC digital operation,electronic module compensate quickly

Adjustments

Simultaneously: AD collected A, B, C phase voltage TRMS to calculate the average and instruction is given to compensate, can effectively improve the unbalance of the three-phase voltage

Separately:Three phase voltage is adjusted to ensure that the three phase voltage is in the range of accuracy, and is particularly suitable for the single phase load.

Automatically:Microcomputer adjust separately or simultaneously by automatic analysis. 

Advanced test

12 bit AD collecting,PLC digital filter and TRMS operation

Accurate control

Perfect coordination of most promgrammable parts with PLC

Human-machine interface

Set data on panel(Output voltage, Voltage accuracy , protection function)

Undistorted output waveform

Non-contact zero-crossing switch, the overlying and Compensating principle of the common frequency, phase lock, sine wave.

Resist harmonic interference

TRMS voltage detection

Wide load range

Resistance, capacitive, inductive load all can be adapted

Slow start resist impact

Voltage regulating before output

Full protection function

When overvoltage and undervoltage occur,can protect witnin 1s or turn to bypass uninterruptedly and automatically,With perfect phase lack, overload, short circuit protection and the post-fault sound and light alarm function.
