EH9335 Series Work mode


  • Three in three out / three in single out UPS
    The series is a three-in and three-out UPS. The input current is three-phase balanced, which can equalize the load of the three-phase power grid; the output can be changed to single-phase output.
  • Digital control
    All parts of the UPS are digitally controlled. The UPS has excellent performance indicators, high system stability, self-protection and fault diagnosis capabilities, and avoids the risk of analog device failure, making the control system more stable and reliable.
  • The number of external batteries is optional (±16/18/20 sections are optional)
    The number of external batteries for this series of UPS can be selected according to the user’s needs: ±16/18/20 knots.
  • Charging current can be set
    This series of UPS automatically assigns a reasonable charge current by setting the user-configured battery capacity. Constant voltage charging mode, constant current charging mode and floating charging mode can automatically and smoothly switch.
  • Intelligent monitoring function
    This series of UPS can realize remote monitoring of UPS when an optional SNMP card is selected.
  • Smart charging method
    This series of UPS uses an advanced two-stage three-stage charging method.The first stage is high constant current charging, quickly recharge about 90% of the power; the second stage of constant voltage charging, can activate the battery characteristics and fully charge the battery; the third stage is floating charge mode.This can balance the goal of fast charging and extending battery life, saving users’ battery investment.
  • LCD display
    This series of UPS uses LCD and LED dual display, which allows users to more intuitively understand the working status and operating parameters of the UPS such as input/output voltage and frequency load capacity, battery capacity and internal temperature, so that all operations can be seen at a glance
  • EPO Function
    An emergency shutdown (EPO) button is embedded on the UPS unit panel,user can externally connect the EPO button. Press the EPO button in an emergency to shut down urgently; and have a remote emergency shutdown (REPO) function.


The EH9335 series is the best choice for data centers, network management centers, and enterprise server rooms in various industries or fields such as telecommunications, finance, transportation, government,manufacturing, and energy.
