outdoor UPS Features: 1) The NETION PHS-300A off-line UPS is designed specially for the sending and accepting set in the relay station of the Xiaolingtong Personal Handyphone System (PHS system) network, which to ensure the un-interruptable communication 2) When the utility power is normal, the UPS supply power to the PHS system through filter and voltage regulation 3) When the utility power is faulted (power stop, low voltage or high voltage), the UPS will switch to supply power by the battery with inverter so that avoid disturbing from the utility power 4) And the UPS will auto self-shutdown when there is long-time fault, which makes the battery charge to too low level due to discharging continually, and it will auto self-startup when the utility power resume normal. It realizes the function of nobody operation and nobody on watch 5) NETION PHS-300A UPS is designed for outdoor use with the functions of sun proof, waterproof and theft proof, easy for installation and maintenance 6) Full-range voltage stabilization aims to the local special power environment, advanced wide input frequency technology can ensure the normal output even when the utility power is in great frequency excursion. Strong load ability which adopts advanced power components to deal with the prominent power change when the sending and accepting set of PHS system at sending moment 7) Good EMC, which adopts advanced technology for preventing the electromagnetism disturbance to protect the equipment, the big power of high frequency charger and advanced 3-class charge method make the time of battery charge shorter, that extend the lifetime of the battery greatly 8) Perfect protection functions: protect the low battery voltage, overload, output short circuit, and avoid the surge and lighting strike 9) Very easy to use and maintain, free watch-keeping realized
