Most Advanced Surge Suppressor in South Africa Today.

Why Do I need a Surge Suppressor?

Many people in South Africa believe that solar equipment can protect their household appliances from power outages caused by load shedding. However, this is not entirely accurate. Even an uninterruptible power supply (UPS) cannot protect electronic devices from the power surges and fluctuations that occur during load shedding. Additionally, insurance companies in South Africa are no longer covering damage caused by power surges during load shedding, which means it is crucial to safeguard our equipment against these harmful power sources.

This is why ECP-AV has turned to Sinetamer to protect our customers’ equipment and provide them with peace of mind, not just for audio-visual devices, but for all electrical equipment in their homes.

About ST-SPT Series (Single Phase, average homes)

The paragraph describes the benefits of using the SineTamer© ST-SPT devices for protecting sensitive and critical equipment from electrical surges. The devices are specifically designed to provide the best protection against ring wave transients, which are sudden voltage spikes that can damage or even destroy electronic devices.

The SineTamer© ST-SPT devices are intended for use in single-phase 120, 240, 380, or 480 VAC circuit applications. They are particularly effective in limiting transients that are generated inside a facility, making them a crucial component for circuits that power critical microprocessor-based equipment.

The devices have a robust 60kA per phase peak surge current rating on all models, which means they can handle large amounts of electrical energy during surges without causing damage to the equipment. They are also designed to be economical, making them a cost-effective option for surge protection.

One of the unique features of the SineTamer© ST-SPT devices is that they are stand-alone surge suppression devices, which means they don’t require a special enclosure when used outside an existing enclosure or cabinet. They are also compact in size, making installation easy and convenient.

Furthermore, the devices come with a warranty that is considered the best in the industry, which provides customers with the peace of mind that they are protected against any potential issues that may arise.

In addition, the SineTamer© ST-SPT devices feature dedicated “all mode” Enhanced Sinewave Tracking™ and a completely encapsulated Optimal Response Network™, which ensure effective and reliable surge suppression.

Overall, the paragraph emphasizes that the SineTamer© ST-SPT devices are versatile, with superior performance specs compared to competitors, and an unparalleled warranty. It suggests that the devices are an essential investment for anyone looking to protect their sensitive and critical equipment from the damaging effects of electrical surges.
