"R" 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. "R" 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 "RI" range. |
