Description
The range consists of several versions for different threats. VoltGuard disconnects the load at both high and low voltage, FridgeGuard reacts to sags, which harm a compressor the most, and HiVoltGuard and TVGuard watch for overvoltage, which is critical for electronics. NotebookGuard is rated for a current of 1–2 A and plugs into the power cord of a laptop. All models also suppress surges and spikes that occur when power is restored. The AVS function opens the circuit when the voltage goes out of limits, and a start delay of 30 s to 3 min keeps the compressor from starting against pressure in the circuit right after a cut-off. The TimeSave mode removes unnecessary waiting after a long power interruption. The cases are made for UK, Schuko, Indian-standard and other plugs.
How to choose
The type of device is determined by the appliance to be protected. For a refrigerator and freezer take FridgeGuard, for a TV or receiver TVGuard or HiVoltGuard, for a PC the universal VoltGuard. If an air conditioner or a whole line has to be protected, the fixed relay AVS13 – AVS100 is suitable, and for a three-phase input AVS303 up to 1250 A.

FAQ
Which Guard should I choose for a refrigerator?
FridgeGuard is meant for a refrigerator; it disconnects the compressor at low voltage and switches it on again with a delay of 30 s to 3 min.
What current are the iS Guards plug-in relays rated for?
The main models carry 6–10 A, while NotebookGuard for a laptop is rated for 1–2 A.
Does VoltGuard protect against surge voltages?
Yes, besides disconnecting at high and low voltage, the adapter suppresses surges and spikes after the mains is restored.
Are there iSense Guards with a Schuko plug for Ukrainian sockets?
The manufacturer makes adapters for UK, Schuko, Indian-standard and other plugs; for Ukrainian sockets the Schuko version is needed.
Why does a plug-in voltage relay need a start delay?
A delay of 30 s – 3 min lets the pressure in the refrigeration circuit equalize and skips the first unstable seconds after the mains is restored.
