mSVR Series - Single-Phase
Voltage Stabilisers / Power Line Conditioners

The Mini SVR Series of Single-Phase AC Automatic Voltage Stabiliser / Conditioners are designed to provide a clean and regulated power supply, thereby ensuring reliable protection against the vagaries of the utility mains supply.

Models are available in 7 different power ratings:

1 kVA (1kW), 2 kVA (2kW), 3 kVA (3kW), 5 kVA (5kW), 7.5 kVA (7.5kW), 10 kVA (10kW) and 15kVA (15kW).

By steplessly boosting low voltages and reducing down high voltages, they ensure a stable output voltage. In addition, Mini SVR Series Voltage Stabilisers safeguard against all too common everyday transient voltages and spikes – typically introduced into the mains supply by nearby disturbances resulting from peak power demands or stop/start operation of electrical machinery.

Suitable for all electronic and electrical load types models are available for situations where the incoming mains utility supply is between 165V to 265V (H Models) and, 90V to 140V (L Models).

NormalAll is working fine
Time DelayDelay in the supply of power to the output on start-up and re-engagement of the output after an irregular event
Display Metering will show a count-down to the re-engagement of the output
High VoltageOutput voltage exceeds the selected over-voltage level. The output will be automatically disconnected. On fault clearance, the output will be automatically re-engaged
Low VoltageOutput voltage exceeds the selected under-voltage level. The output will be automatically disconnected. On fault clearance, the output will be automatically re-engaged
OverloadThe actual current drawn on the input supply exceeds the models stated maximum input current rating. LED will indicate an overload condition for 60 seconds and then the output will be automatically disconnected. On fault clearance, the output will be automatically re-engaged
