 SBW-F Sub-tone automatic compensation power voltage stabilizer

Selection prompt

Please use the normal conditions of use of the regulator(power supply)

For three-phase unbalanced electricity grid special place(refer to A,B,C phase voltage deviation more than 10%):in order to ensure the regulator output voltage accuracy,please selectSBW-F series regulator.

For the coal mines,tunnels and other special use areas.because there are long lines and large pressure drop factor,ordering .Please provide details of the use of premlises length of the wire,the wire load area,power transformer capacity  and maximum load current and other information,according to the company

 the actual situation of power regulatorconfiguration.Otherwise ,it will cause the

 regulator after use will not achieve

the desired voltage regulation.
