POWER FAILURE COMPENSATION DEVICE

WHAT IS INSTANTANEOUS POWER FAILURE?

Instantaneous power failure is a momentary (usually within a second) voltage drop. Instantaneous power failure is caused by both lightning, rain, snow, construction trouble and the cause of wild animal etc. and by the fall and short circuit of the power supply track. Instantaneous power failure is one of the unstable unexpected elements in modern industrial sector. Instantaneous power failure not only severely affects production operation of facilities that requires high precision, but also causes serious troubles such as poor quality delivery delay due to falling productivity.

POWER FAILURE COMPENSATION DEVICE

OKY's Power failure compensation device will protect sensitive equipment from being tripped by short duration of power supply quality problem. In short, OKY's Power failure compensation device enhances operation reliability of the equipment and protects precision equipment against such electrical problem without actual user’s additional hardship, as it is a complete maintenance free device. Also a lot of malfunction which happens in electronic components and circuits could be prevented with OKY's Power failure compensation device.

OPERATION THEORY OF POWER FAILURE COMPENSATION DEVICE

During the normal status, input voltage directly flows to main equipment through device's bypass line. (see the blue arrow) At the same time charging process works to EDLC. When detecting Voltage drop or low voltage level input voltage cut off then EDLC energy is supplied to main equipment. The switching works within 2ms(0.002 sec) from Voltage drop detection to compensation voltage supply. Power failure compensation device mode changes as Stand-by when original power line is recovered.
