Three phase power regulator

Application situation (DBW SBW single phase and three phase full automatic compensation power regulator)

The voltage regulator (regulated power supply) is widely used in large mechanical and electrical equipment, metal processing equipment, production line, construction engineering equipment, elevator, medical equipment, embroidery and textile equipment, air conditioning, radio and television, household electricity, lighting and other places in the field of industry, agriculture, transportation, post and telecommunications, military, railway, scientific research and culture, etc. SBW and DBW series regulators should be used indoors. The normal operation conditions of the voltage regulator (regulated power supply) are as follows:

● ambient temperature: - 15 ℃ ~ 40 ℃

Altitude lt; 1000M

Relative humidity lt; 90%

There shall be no gas, steam, chemical deposition, dust, dirt and other explosive and corrosive media that seriously affect the insulation of voltage stabilizer.

There is no serious vibration or turbulence in the installation site.

Main technical parameters (DBW SBW single phase and three phase fully automatic compensated power voltage regulator)

Input voltage: single phase 220 V ± 20% or 220 V ± 30% (to be specified when ordering)

Three phase (three-phase four wire) 380V ± 20% or 380V ± 30% (to be specified when ordering)

Output voltage: single phase 220 V

● three phase (three-phase four wire) line voltage 380V or phase voltage 220V

Output voltage accuracy: (2-5%) adjustable
