· UPS Power Supply to Solve The Interference Problem
1. power failure protectionInstantaneous power failure as soon as the battery from the UPS to convert AC to DC power supply.
2. high and low voltage protection
Mains voltage is too high or too low when the UPS built-in voltage regulator (AVR) will make the appropriate adjustments, the mains voltage maintained at the range can be used, if the voltage is too low or too high can be used over the scope, UPS will be Battery DC power supplies convert alternating current to power to protect user devices.
3. waveform distortion processing
Due to power through the transmission and distribution lines sent to the client, the use of a variety of machinery and equipment, often caused by mains voltage waveform distortion, as distortion will produce a harmonic wave jamming equipment and make electric power system transformer temperature increases, the general requirements for distortion rate (%)＜5%, the general design of distortion UPS rate (%)＜ 3%.
4. frequency stability
50Hz/60Hz mains frequency is divided into two kinds, the so-called changes in the frequency is every second cycle, 50Hz is the second 50 weeks times, Taiwan mains frequency is 60Hz, the mainland is 50Hz. Generators running the client is subject to sudden changes in electricity consumption caused by changes in speed will allow conversion out of the power frequency drift uncertainty, UPS power conversion can provide a stable frequency.
5. voltage stability
Mains voltage is vulnerable to the impact of the quality of electricity transmission lines from the substation closer to the user a higher voltage of about 130 ~ 120V, the user further away from the substation low voltage of about 100 ~ 90V, voltage too high or too low user equipment will shorten the life span, and in severe burning equipment, the use of on-line UPS can provide stable voltage supply, voltage changes less than 2V, extend equipment life and protection equipment.
6. transverse-mode noise suppression (TRANSVERSE MODE NOISE)
Transverse mode noise generated on the front lines between the lines and the neutral.
7. suppress common mode noise (COMMON MODE NOISE)
Common-mode noise generated in the firing line / neutral between line and ground.
8. Surge Protection
UPS will normally install Surge absorber designed to absorb the surge or a point discharge to protect the user equipment.
9. transient response to protect the
Electricity disturbance sometimes causes Voltage protruding (SPIKE) or depression (NOTCH), or transient voltage drop (TRANSIENT), the use of on-line UPS can provide a steady voltage, the voltage change in less than 2V, extend equipment life and protection of Device.
10. monitor power supply
UPS with intelligent communication interface and monitoring software can record the mains voltage frequency outage time and frequency to achieve power control, and can arrange a timetable for UPS timer switch to conserve energy.
