VR — single-phase voltage stabiliser 0.5–5 kVA
Country: United Kingdom · Model: VR
The inexpensive VR single-phase stabiliser of 0.5–5 kVA protects office and household equipment, that is, air conditioners, computers, refrigerators and TVs. The G version works from 80 V, so it withstands deep voltage dips in rural grids.

Description
The unit is static, with no servo drive or brushes, so it has no mechanical wear. The F version is designed for a 140–270 V input and suits city grids with moderate fluctuations. The G version holds the output when the voltage falls to 80 V, which happens at the end of long lines. Efficiency is at least 98 %, so the stabiliser hardly heats up. Built-in protection suppresses surges and overvoltage that would otherwise reach the power supplies of the equipment. The manufacturer gives a 2-year warranty.
How to choose
First measure the minimum voltage at the socket during the evening peak. If it does not fall below 140 V, the F version is enough, and for deeper dips take the G. Calculate the power from the sum of consumers, allowing for the starting current of an air conditioner or refrigerator compressor. For an IT load that requires 230 V ±1 %, the PWM for 2.1–14 kVA is more suitable.

FAQ
From what minimum voltage does the VR stabiliser work?
The G version works from 80 V and the F version from 140 V. The upper limit for both is 270 V.
Is the VR suitable for a refrigerator and an air conditioner?
Yes, the series is designed precisely for household and office equipment. Calculate the power up to 5 kVA together with the compressor starting current.
What is the warranty on the VR stabiliser?
The manufacturer gives a 2-year warranty on VR stabilisers.
Does the VR protect against surges?
Yes, the stabiliser has protection against surges and overvoltage, which protects the power supplies of computers and TVs.
What is the efficiency of the VR stabiliser?
At least 98 %, so the unit's own losses are negligible even at a 5 kVA load.
