Outdoor ups

Outdoor ups

Online Outdoor UPS is specially designed for outdoor communication, networking
equipment which provide pure uninterrupted AC power equipment and primarily use in city corner, countryside, or mountain area. A series designed measure with high temperature resistance, frost resistance, corrosion resistance, dust prevention and waterproof and anti-lightning protection, also with wide input voltage range and frequency range: pure, stable and reliable output waveform etc. It completely solves the networking communication equipment’s interference and power interrupted in poor power supply environment. Therefore, this online outdoor UPS is widely used in communication, broadcasting, aviation and other fields of outdoor communication base station power supply

Strong environmental adaptability

    • P55 protection. dust prevention & waterproof, perfectly fits in poor environment
    • High and low temperature resistance, operating normally at -30°C to +65°C
    • Anti-lightning protection, the system equipped with no less than 1.2KV/10KV pluggable SPD Wide adaptability to power grid
    • Wide input voltage range and frequency range from 11 OVac to 300Vac and 40-60Hz, perfectly ts in poor power grid environment
    • High voltage protection circuit, can exceed input voltage range without damage
    • Online double conversion construction, completely eliminate the communication equipment’s interference

Variety of accessories base on demand

    • Provide variety of optional installation accessories, depends on your demands with rack mounted type or tower type, and so on.
    • Provide the function of twice power off, UPS can be set to power off unimportant load in battery mode, which will insure the backup time of important load. Provide the dry contact for twice power off.
    • Can be fixed with a SNMP card to do remote monitoring and managing, which will provide real-time information and data of UPS.
    • Dual conversion technology and Os for switch between AC mode and DC mode, which will ensure never power off of load.
    • With unmanned surveillance management, when batteries run out of energy, and AC is resumed, UPS will start automatically to take load.
    • With fault diagnosis function, can analyze the fault through LED quickly.
    • With cold start function, can start UPS with batteries without AC power, which can satisfy demands of emergency power supply.
    • Contain the RS232 port and dry contact port, which will be convenient for communication with monitor device.

Advanced technology and powerful function

    • Adopt DSP digital control technology, and simplify the control circuit, which will improve system reliability effectively.
    • Adopt PFC circuit to raise the input power factor, reduce the harmonic pollution from UPS.and raise the utilization factor of the grid, reduce the
      cost of UPS working.
    • The efficiency of UPS will be more than 90%, which will reduce the waste and temperature in cabinet
