Appliances such as air-conditioning and refrigeration units are particularly vulnerable to damage caused by low voltage ‘brownouts’. With the A/C Guard, your equipment is protected against all power fluctuations: over-voltage as well as low voltage, spikes, surges, power back surges and power fluctuations. Part of Sollatek’s highly versatile Voltshield Range which uses the Sollatek Switcher technology, the A/C Guard switches off the air-conditioner instantly when a power problem occurs, reconnecting it only once the mains supply has stabilized. The A/C Guard is easily installed by an electrician and suitable for use with all air-conditioners, including split units, as well as industrial refrigeration equipment. Once it has been directly wired between the mains and your appliance, the A/C Guard provides complete protection automatically. The A/C Guard’s Automatic Voltage Switcher functions protect against Low voltage, high voltage, power-back surges, power fluctuations and surges/ spikes. It features a start up delay of about 4 minutes to prevent frequent switching on and off during fluctuations. The A/C Guard has a built-in microprocessor which adds the advanced feature Time Save to save on down time. Time Save means that when the mains returns to normal after any event, the A/C Guard checks the duration of the OFF time. If the unit has been off for more than 4 minutes then it will switch the air-conditioner on within 10 seconds rather than the standard 4 minutes. If however, the unit has been off for less than 4 minutes, the A/C Guard will ensure that it will remain off up to 4 minutes and then restarts automatically. An integral circuit breaker enhances the protection offered by the A/C Guard. If a short circuit or over-load occurs, the circuit breaker detects the fault and the air conditioner is safely disconnected.
