SCR Type Voltage Regulator
The use of microcomputer intelligent detection, output commands to control the controllable silicon module (SCR) of fast switching, the same frequency, phase locked through a transformer, sine wave superimposed compensation to maintain the stability of the output voltage, fast response speed, no carbon brush, no contact, no mechanical, no spark ,three-phase distribution.
Three-phase regulation, no contact, no abrasion, no spark and maintenance free, Regulator speed to 0.05s can be accessed by all types of generators.
Fast, stable to the rated voltage value of the time less than 30ms, capable of suppressing input low voltage surge, immediate and effective protection of precision equipment.
Display button to set the parameters, convenient, user-friendly
Average fault-free uninterrupted work more than 100000 hours
No additional waveform distortion(static state)
98%
None
None
All products have a fist voltage output function
Abnormal situation after 30ms protection
With overload, short load, short circuit, lack of phases, and automatically bypass protection function.
Carbon Brush Regulator(SBW/DBW/SVC/TNS/TND)
Rely on the carbon brush rack in regulating transformer on the mobile to change the compensation transformer the secondary winding voltage to maintain the stability of the output voltage. Carbon brush, a contact point, mechanical transmission.
Regular intervals maintenance,slow regulated,three-phase unified adjustment,unbalance output,Carbon brush wear, motor malfunction by jammed,coil spark..
Slow (3~5s), motor adjust( mechanical)
The analog potentiometer adjustment, or can be set
Carbon brush is easy to wear,motor often jammed,the average life expectancy of 8760 hrs.
