Information Guide About Automatic Transfer Switches
Automatic transfer switches, electrical devices, are basically used for transferring the power source from one power supply to another. They are known as automatic switches as they operate successfully, without human intervention. The transfer of power sources takes place when main utility power fails and power is provided via emergency power backup devices like UPS, generators, etc. So, let’s explore more about these switches in detail.
Functions performed by the Switches
The main functions performed by automatic transfer switches include:
• Transferring power from one (primary) source to another (secondary) when main utility power deviates from standard limits.
• When the main power regains its desired limits, then these switches transfer the power back to the main power.
• The switches keep electrical devices separated from one to another; therefore they help in preventing power surges.
• They continuously monitor voltage levels and circuits for power surges, spikes, blackouts, etc.
Other important functions that are performed by automatic transfer switches include as soon as the main power interrupts, these switches send the signals to generator and generator starts working. Once, the generators start running at its normal speed, the switches safely and securely open ups the generator power line and shut off the main power line. In this, it can be said that these switches not only help in protecting homes or offices from sudden power break up, also protects the generator or UPS.
Other important information about the switches
These switches consist of a relay control, service disconnect circuit breaker, a terminal wire and fuses. When any fault occurs in the main utility power, these switches get connected with the UPS or generator via terminal wires. Even in the complete power loss, the switches perform their function appropriately.
These switches can be appositely used for controlling electric discharge lamps, motors, electrical heating equipment, etc. It is advised that before operating or installing automatic transfer switches, read the precautions and safety rules carefully in order to avoid any mishap. For getting the best result, always seek professional assistance in installing these switches. One can easily buy the switches from numerous online sources that not only sell them, but also provide installation services at affordable rates. For gaining more information about the switches, browse the web.
