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).
