Low Frequency Online UPS

Low Frequency Single Phase (1/1) Online UPS

EH9115 Series (2-40KVA)

MUST this series are 1 phase in 1 phase out UPS. Their capacity range from 2KVA to 40KVA. These series have applied full digital control technology based on DSP (digitized signal processor). IGBT transformation endures high power current and high voltage with an extremely low consumption. The machine can run self-diagnose, and with standard RS232 for SNMP or RS485 cards, they are conveniently managed by central monitoring and remote monitoring. The latest Redundancy Parallel Array technology is available with these series. RPA function can operate on up 32 units.

Product Performance

  • Full digital control
    Applying full digital control technology based on DSP, That is ensure output pure sine wave, And make the UPS output is stable and safe.
  • Output isolation transformer
    Effectively block the impact of the load on the UPS, ensuring safe and reliable operation of the load.
  • Strong load capacity
    The UPS output has good dynamic characteristics and strong impact resistance.It can achieve 0 to 100% load change without switching to bypass, and it has a strong ability to mix loads.
  • Transfer time
    The transfer time between inverter mode and bypass mode is less than 2ms.It guarantees safe and reliable operation of the load.
  • Cold start
    DC start (cold start), convenient to operate.
  • Parallel (redundant parallel) function
    Up to 32 UPS parallel units can be implemented.
  • Auto re-start function (Optional)
    When the utility is abnormal, the battery mode is powered until it is automatically turned off. When the utility returns to normal,The UPS can choose automatic or manual restart. And return to normal power supply.
  • Complete security protection
    With input and output over and under voltage protection, battery overcharge and over discharge protection, output overload protection and alarm functions such as short circuit protection and over temperature protection.
  • Ultra-wide input voltage range
    Provides complete protection for critical equipment in a variety of harsh electrical environments.
  • Self-diagnose function
    When the power is turned on, the UPS starts to automatically check the critical working circuits.It is convenient to find problems in time and avoid any loss.
  • Parallel system adopts advanced synchronous current sharing control technology.
  • Wi-Fi function Optional.
