Linear TV Guard 5A

Linear TV Guard 5A: Essential Electronics Protection

The Linear TV Guard 5A is a specialized voltage monitoring device designed to protect televisions, home theatre systems, and other sensitive electronics from the damaging effects of voltage fluctuations . Unlike simple surge protectors, this unit continuously monitors the mains voltage and disconnects the appliance when unsafe conditions are detected.

Voltage fluctuations are common in many areas and can cause significant damage to sensitive electronic components, power supplies, and circuit boards. High voltage stresses components and causes overheating, while low voltage can cause power supplies to malfunction or draw excessive current .

This TV guard automatically cuts off power when voltage goes outside safe limits and restores power only when stable conditions return, ensuring your expensive electronics remain protected at all times.

Linear TV Guard 5A: Key Specifications

Linear TV Guard 5A: How It Works

The TV guard continuously monitors the incoming mains voltage using microprocessor control for accurate detection . When voltage remains within the safe operating range, power flows normally to your equipment.

If voltage rises above the safe upper limit, the internal relay instantly disconnects power to the appliance . This prevents sensitive electronics from operating under damaging high-voltage conditions.

When voltage returns to safe levels, the unit does not reconnect immediately. Instead, it waits for a pre-set 30-second delay period . During this wait mode, the yellow LED indicates the guard is monitoring the supply. At the end of the delay, if voltage remains stable, the green LED lights and power is restored .

Linear TV Guard 5A: Comprehensive Protection

This TV guard offers multiple layers of protection for your valuable electronics :

Over-Voltage Protection: Disconnects power when voltage rises too high, preventing damage to sensitive components.

Under-Voltage Protection: Protects against brownouts and low-voltage conditions that can stress power supplies.

Surge and Spike Protection: Suppresses sudden voltage spikes and transients that can destroy electronics.

Lightning Protection: Provides a degree of protection against voltage surges induced by lightning strikes.

Power Back Surge Protection: Guards against surges that can occur when power returns after an outage.

Linear TV Guard 5A: LED Status Indication

The unit features clear LED indicators showing operating status at a glance :

Red LED: Initial power-up or fault condition – monitoring supply or power disconnected.

Yellow LED: Wait mode – 30-second delay counting down before reconnection.

Green LED: Normal operation – voltage safe, power connected to appliance.

This visual feedback helps you quickly understand why your equipment may not be receiving power.

Linear TV Guard 5A: Important Usage Guidelines

To ensure reliable operation and maintain warranty, follow these important guidelines :

1. Do not exceed 5 amps: Ensure your connected equipment draws no more than 5 amps total. Exceeding this rating may damage the guard and void warranty.

2. Single appliance use: Do not connect multiple appliances to one TV guard through extension leads or multi-way adapters.

3. Correct connection: Plug the TV guard directly into the wall socket, then plug your appliance into the guard.

4. Leave switched on: It is recommended to keep the TV guard switched on continuously, and switch your appliance on and off as needed. This prevents activating the 30-second delay every time you use your equipment.
