Why hasn’t the voltage display changed but my input voltage has changed?

The SVS corrects the input voltage in increments (taps). If the input voltage moves form one tap to another, the output voltage can move visibly but remain within the output parameters of the unit. For example, as per table, if the input voltage is 240V, output is 240V. If the input moves up to 245, the output moves to 218. The LED display will remain unchanged in this instance as the output is still within the parameters (6% accuracy).

What is the most suitable stabiliser for a vaccine fridge?

The most suitable stabiliser for a vaccine fridge is the following Sollatek product: Model : Sollatek SVS04-22 4A 1KVA 230V EURO 6min E7/VR . This SVS is designed specifically to protect vaccine fridges and complies with WHO specification E7/VR. The unit is rated at 4amps on full load and full boost and has a start up delay of 6 minutes.

Which stabiliser can be used on the output of a generator? SVS range or AVR range?

Either would, both are suitable. Use an AVR if the main equipment are computers or computer like equipment. However, some small generators produce a wave shape may cause problems for the AVR/SVS measurement circuit. You can get very large frequency fluctuation too. Make sure the gen set is rated to at least twice the required current so as to reduce some of these problems. The Sollatek SVS is also Genset compatible and that would be the model of choice for small generators.

Description

The Sollatek SVS monitors the mains voltage continuously. If the voltage rises or drops, the SVS will stabilise the output to ensure the voltage reaching your equipment remains constant at 230V (+/-6%), within the operating range of the unit. If the input voltage falls below 142V or rises above 295V, the SVS will disconnect the output, thereby protecting the load. Once the mains voltage returns again within acceptable limits, the SVS will reconnect the output following a start up delay.

The SVS02 and SVS04 are small light weight stabilisers rated at 2Amps and 4Amps. Available in various socket types, see table below.
