DESCRIPTION: Three-phase voltage stabilizers Volter (SNPTT) 200 kW consist of four units - three phase stabilization units and one switching unit. The stabilizer is connected to a three-phase network via the switching unit. The connection is made according to the "star" scheme with a mandatory neutral wire. On the front panel of the switching unit there are: - a circuit breaker; - LED indicators of the presence of input voltage and output voltage; - voltmeters of input and output voltage; - two voltmeter switches that allow you to alternately measure the phase and line voltage both at the input and at the output of the stabilizer; - an input current ammeter; - an ammeter switch by phases. On the top panel of the phase unit there is an operating mode switch, on the front panel there is a liquid crystal indicator and control buttons. Each step-up phase voltage stabilization unit consists of an autotransformer with terminals, power keys and a voltage controller. During operation, the controller monitors changes in the input phase voltage and, based on the measurement results, switches the power keys, maintaining a stable autotransformer magnetic flux and a stable stabilizer output voltage. Advantages: Silent operation, Improved heat dissipation without a fan, Increased noise immunity, High response speed, Operation at sub-zero temperatures and high humidity, Enhanced fire safety, Maintenance-free, Maximum number of protections, Convenient connection, Does not distort the sine wave, Resistant to mechanical impact, High overload capacity, Increased reliability. Optimal reliability/price ratio.
