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).

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 SVS20 is a small light weight stabiliser rated up to 20Amps with a cable or terminal input/output, for direct wiring and secure connectivity. See connections tab above.
