"VSM" automatic voltage stabilisers with electronic control are designed for power supply applications in computer centers, control systems, numerical control machine tools, and in any situation where a rigorously constant voltage is required.

"VSM" stabilisers are particularly versatile, they have a high efficiency, they support high transient overloads, frequency and load variation. With a very high accuracy, they are provided with a FINE VOLTAGE REGULATION knob, which enables the operator to select the optimum value for all load and conditions.

They are also equipped with: a reliable digital voltmeter with input and output voltage reading, mains light. Automatic circuit breaker, input and output connectors are positioned on the rear side.

All models are available with isolation transformer in the "VSMI" range.
