Voltage Regulator (DBW/SBW automatic compensated type)

General

DBW . SBW series single - phase and threephase full automatic compensated voltage regulator (hereinafter referred to as voltage regulator or stabilizer) is designed for stabilizing AC voltage and made with Western Europe advanced technology and on the basis of our country national conditions .

It can keep output voltage in steady state automatically when the power network voltage fluctuates or the load current varies. Compared with other voltage stabilizers, it has the advantage of large capacity, high efficiency, no wave distortion, stable voltage adjustment, suitability for kinds of loads, bearing instantaneous overload, working continually for long time, as well as free transferring between manual control and automatic control, etc, besides, it is provided with protection against over-voltage, over current, phase failure and protection for phase sequence and has following merits: small volume, light weight, convenient installation and reliable running and so on.

It can be applied to large type electromechanical equipment, metal processing equipment , production line , construction device , elevator , medical equipment, equipment of light and textileindustry, air-condition, TV set, household appliance and lighting used for industry, agriculture, traffic, military, railroad, scientific culture, etc, where need voltage stabilization.

Input voltage:
Three-phase: three-phase four-wire phase voltage 220+20%, wire voltage 380V+20% or phase voltage 220+30%, wire voltage 380V + 30%,
they can be selected ( please indicate when placing an order) Single phase: 220V+20% or 220V+30%, it can be selected ( please indicate when placing an order)
Output voltage:
Three-phase: three-phase four-wire phase voltage 220V, wire voltage 380V
Single-phase: 220V
Accuracy of output voltage: 2-5% (adjustable)
Efficiency: ≥95% ( power class: more than 50KVA)
Response speed: ≤1.5S (when outside voltage has 10% of change)
Waveform distortion: no additive waveform distortion
Protection : protection against over voltage , over current , phase failure and machine fault, as well as phase sequence protection (single-phase and three-phase 150KVA below has no phase failure and is provided with phase sequence protection).
Voltage stabilization, convenient switching for commercial power (single phase has no function)
Start automatically or by hand (can be chosen) when power is on.
Can work continuously for a long time without anybody attending.
Insulation resistance: ≥2MΩ
Electric strength: bear power frequency sine voltage 2,000V for 1 min without breakdown or flash over.
Overload capability: 2 times rated current, keeping 1 min (voltage stabilizer special for elevator and CT)
