High Frequency Online UPS

EH9335 3/3 Rack Mount Series (10-40KVA)

EH9335 is new generation of high-frequency on line UPS developed, which use with Advanced DSP digital control echnology. Effectively improve product performance and system reliability, and achieve higher power density, with features such as small size, light weight, and high work efficiency, etc. This series of UPS can solve almost all power problems, such as power outage, city power high voltage, city power low voltage, voltage drop, amplitude reduction, Power problems such as high voltage pulses, voltage fluctuations, surge voltages, harmonic distortion, clutter interference, and frequency fluctuations to provide the best power environment for the load. Adopt 3U rack structure to be installed easily.

Features:

  • Double conversion online design

  • Ultra-wide input voltage range
  • Input frequency range of 40 ~ 70Hz
  • With active power factor correction technique(PFC)
Get Pricing/Info


• Double conversion online design, 0ms exchange output, single input and single output voltage.
• With DSP digital control technology, Excellent performance index, the control system more stable and reliable.
• With active power factor correction technique(PFC),Input power factor close to 1, greatly reducing the pollution of the electricity grid.
• Ultra-wide input voltage range.
• Input frequency range of 40 ~ 70Hz, to ensure access to a variety of fuel generators can work.
• LCD + LED using real-time display, the user can intuitively understand the operating state of the UPS.
• Has turned self-diagnostic function, can detect hidden faults of UPS.
• With AC input over-voltage and under-voltage protection, output overload protection, short-circuit protection, temperature protection, battery under-voltage warning protection and battery overcharge protection, etc.
• Overall efficiency 94.5% reduction in power loss of UPS, saving the user’s cost.
• When there is no utility power, it can directly use the battery to start working.
• When the utility power is restored, the UPS can automatically turn on and charge the battery at the same time to realize the unattended function.
• When the electricity is interrupted, UPS will discharge untill power off during battery mode.
• The standard RS232 communication interface enables multi-functional and multi-purpose monitoring and management operations between the UPS and computer through a computer window, and an SNMP card (optional) can be installed to realize the UPS remote monitoring function.
