A power board is designed for providing electric power to electronic devices and electric appliances. When using a power board it is important to take the necessary safety measures to minimise the risks. If it is used incorrectly a power board can cause electric shocks, fires, serious injuries or death.
In Australia a power board offered for sale must respect the safety standards. When you purchase a power board you have be sure that it has been approved for use in Australia and tested for safety. The safety approval details are listed on the back of any power board. To be approved a power board should include overload protection measures. That will prevent overheating the device and will ensure it will not cause electrical shocks and fires.
It is not advised to overload your power board with multiple appliances. Using double or triple adaptors can be one of the major causes of fire. It is also not advised to connect to a power board those appliances with high electricity use, such as air conditioning devices. It is better to connect them directly to the wall power outlets. Do not use the power boards outdoors or in wet areas.
A power conditioner is a voltage regulator device designed to improve the quality of the delivered electric power by various means such as noise suppression or power factor correction. Its function is to smooth the sinusoidal AC wave form and to keep a constant voltage over different loads. A power conditioner usually provides surge protection as well. During the malfunctions of the main power grid or during the storms may appear some voltage spikes that can damage your home appliances and electronic devices. A power conditioner can protect the sensitive equipment by shutting off the power source in case of voltage spikes.
A good power conditioner features internal filter banks with the role to isolate the individual power outlets on the power conditioner. This helps to eliminate the interference between components. For sensitive equipment such as a home theater system it is important to have a proper noise suppression of the electric power received. The noise suppressing rating is expressed in decibels and a better noise suppression has a higher decibels (db) rating.
Another parameter listed on a power conditioner is the joule rating. That measures how much electrical energy can be absorbed by the power conditioner before becoming damaged. A higher protection capacity is expressed in a higher joule rating.
There are many types of power conditioners that vary in size and function. Some of them are designed only for the basic function of voltage regulation while other power conditioners are capable to protect against many electric power quality issues. The power conditioners can vary in size from units large enough to protect an entire factory to small units mounted on a printed circuit board.
For home use you may need a whole house surge protector located at the electrical panel and a point of use power conditioner for your sensitive AV systems.
Proper use of power boards and power conditioners in your house will assure your safety as well as the safety of your sensitive electric and electronic equipments and will improve their functioning.
