Latest UPS / Voltage regulators / Generators


An uninterrupted power supply is used to prevent total power failure to computers during a power failure or power fluctuations.

UPS running time

A UPS provides temporary power in the event of a power failure.
The UPS provides 5 to 10 minutes of backup power while an alternative power source, such as a generator, is switched on.

A UPS is good as additional protection against damage from electrical spikes or dips.

An inverter is recommended to get more time from battery backup!

Voltage regulator

A Voltage regulator maintains a constant and regulated voltage to sensitive equipment such a monitors and computers, and prevents data loss and electronic failure.

A voltage regulator  stabilizes power from an unstable source, such as a petrol or diesel generator.

A Voltage regulator will not correct frequency problems (50Hz in South Africa)

UPS keeps switching on and off while using a generator

UPS are sensitive to the voltage and frequency on its input - this is the way it detects whether it should switch to battery backup mode or not. This is normal operation for a UPS.

Some generators, especially the cheaper "home use" generators, are not always calibrated accurately when it comes to frequency (50Hz in South Africa), while the voltage seems to be in range. If the frequency is border-line, the UPS tends to switch over to battery mode whenever it falls out of range, and then switches off when it is in range again.

The best way to correct this on/off behaviour is to set the throttle on the generator to a point where the UPS becomes stable.

Note: A Voltage regulator / AVR will not correct the frequency and will do little to fix this behaviour. An AVR is all about Voltage, and the AVR will fix voltage fluctuations from a generator, protecting sensitive equipment from Voltage dips and spikes.
