Uninterruptible Power Supply

Buy UPS in SingaporeAn uninterruptible power supply, or UPS, is a device that provides battery backup power which allows electronic devices, such as NVR/XVR/DVR of CCTV Cameras, servers, computers, internet routers, to continue running for some time when the primary power source is down. Another important function of UPS is to provide protection during power surges, such as lightning (which can be very common in Singapore). Without UPS, unexpected power disruption could cause data loss or business disruption, which can be quite serious.

There are three general types of UPS: on-line UPS, line-interactive UPS and standby UPS.

An on-line UPS uses a "double conversion" method of accepting AC input, rectifying to DC for passing through the rechargeable battery (or battery strings), then inverting back to 100V-230 V AC for powering the protected equipment.

A line-interactive UPS maintains the inverter in line and redirects the battery's DC current path from the normal charging mode to supplying current when power is lost.

In a standby, or offline UPS, the load is powered directly by the input power and the backup power circuitry is only invoked when the utility power fails.
