Product description

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 agaist all power fluctuations: over-voltage as well as low Voltage,spikes,surges,power back surges and power fluctuations.

Part of Voltstar’s highly verastile Voltshield Range which uses the 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 stabilised.

Simple installation-complete peace of mind

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, Choose between 16,20 or 25Amp models to match the rating of your air conditioner or load.

Sophisticated protection

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 microprocess or which adds the advanced feature TimeSaveTM to save on down time. TimeSaveTM 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 minutse. If however, the unit has been off for Isee than 4 minutes, the A/C Guard will ensure that it will remain off up to 4minutes and then restarts automatically.

Circuit breaker function

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. To resume operation, simply switch the A/C Guard circuit breaker on again, assuming the cause of the overload has been removed. The air conditioner will restart automatically after an intelligent time delay.

Scope of application

Protection for Air conditioners·Large fridge/freezers·Whole office·Direct wired equipment
