DESCRIPTION: The Volter™-150 c consists of four units: three phase stabilization units and one switching unit. The phase unit's top panel houses the operating mode switch, while the front panel features an LCD indicator and control buttons. Each step-up phase voltage stabilization unit consists of an autotransformer with terminals, power switches, and a voltage controller. During operation, the controller monitors changes in the input phase voltage and, based on the measurement results, switches the power switches, maintaining a stable autotransformer magnetic flux and a stable stabilizer output voltage. The stabilizer is connected to a three-phase network via a switching unit. Connection is made using a star connection with a mandatory neutral conductor. Advantages: large phase imbalance at the input is allowed, each block operates independently of the others and controls its own phase; the stabilizer is not afraid of an asymmetrical load at the output (by phase from idle to maximum load); ease of installation and transportation of three single-phase blocks (the weight of a three-phase stabilizer is 100-700 kg); Specifications: Type - electronic thyristor Phase - three phases Efficiency, % - 98 Input range - 125-265 V (per phase) Response time, ms - 20 Noise level, dB - 34-40, depending on the load Maximum current, A - 250 Maximum power, kW - 165 Cooling - natural Mounting method - floor Output voltage - 220 V Max.
