Technical index

SCR Type voltage regulator(SPZW)

Carbon brush regulator(AVR)

Working principle

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.

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.

Features

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.

Regular intervals maintenance, slow regulated,

three-phase unified adjustment,

unbalance output,

Carbon brush wear, motor malfunction by jammed , coil spark..

Response time

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.

Slow (3~5s), motor adjust( mechanical)

Parameter setting

Display button to set the parameters, convenient, user-friendly

The analog potentiometer adjustment , or can be set

Service life

Average fault-free uninterrupted work more than 100000 hours

Carbon brush is easy to wear, motor often jammed, the average life expectancy of 8760 hours.
