  • Product description
    Working Mode: Single phase in Single phase out, Low frequency, online double conversion
    1KVA-15KVA online smart UPS is a high stability uninterruptible power supply specially design according to the China Power Grid environment and network systems for high reliability requirements.
    High Reliability Design  Dual-transformation online mode design, making the UPS output the pure UPS with frequency follow-up, locked phase and stable voltage, filtration of distortion degree, low distortion degree and no interference of the fluctuations in power system,and making UPS provide more comprehensive and perfect protection for the user' device.  Zero transformation design for output, meeting the high-standard requirements of the precision equipment for power source.
    High load Protection Capacity  Equipped with the output separation transformer in the machine, and high immunity from interference, providing more comprehensive and perfect protection for the user' device.  Very tiny zero voltage difference, meeting the power supply demand of the precision equipment and device and protecting the safe operation of the device.  Good load compatibility, suitable for loads of different types and meeting the demands of all application situations.
    High Environmental Adaptation  The wide voltage input range reaches 150-310 VAC (add AVR), avoiding from frequently switching to the power supply of thebattery, and suitable for the areas with bad electric environment.
    High Battery Optimization Performance  Intelligent battery management technique, extending the service life of battery and reducing the times of battery maintenance. Advanced constant-voltage charging technique, activating the battery to the maximum extent, saving the charging time and extending the service life of the storage battery.
