HEPower Series (Transformerbased UPS)

Category Products
by Heracon

HEPower UPS series is specially designed for medical applications (protecting diagnostic imaging equipment such as CT, MRI, and DSA systems ) as well as industrial loads (motors with variable frequency drives, soft starters, welding and cutting machines, CNC machines, printing systems, textile machinery, and dairy and coffee processing industries, etc)

Online Double Conversion

  • Online Double Conversion design helps to output a pure sine wave, which is immune from the UPS input, so that the load can run steadily
  • UPS transfers among different working mode without output interruption, thereby powering the load uninterruptedly

Full DSP Control

  • Double DSP control makes the whole system more stable and reliable

N+X Parallel Redundancy

  • N+X parallel redundant design, up to 6 units available, makes the configuration more flexible
  • Any unit in parallel system fails, the faulty one will automatically cut off the output, and the load will be powered by the remained units
  • It is easy to configure the parallel system just by connecting the parallel cables and doing proper settings
  • Non-fixed Master-Slave relationship: Among several UPS in parallel, the unit startup first is Master UPS, the others are Slave. The master and slave may be exchanged

High Power Factor

  • The output power factor up to 0.9 better matches the load
  • The input power factor 0.97 with filter helps to improve the efficiency, reduce the harmonic pollution to the Grid and lower the UPS running cost

Wide Input Adaptability

  • The range of AC input voltage is (380/400/415Vac) (-25%/+20%), minimizing transfer to battery mode, thereby greatly prolonging the battery life
  • Wide input frequency ranging from 45Hz to 65Hz, ensures stability of UPS while generator connected

Optimized Battery Management

  • Intelligent battery management system and advanced battery auto float/boost charge technology, reduces the frequency of battery maintenance, greatly improves the battery efficiency and extends battery life
  • Battery discharge time prediction: The system will display the backup time of battery calculated by discharge current and voltage
  • Battery self-test: Battery is automatically tested at regular intervals
  • Flexible battery voltage configuration

Power Walk In

  • Specially designed power walk in function, in which rectifier of each unit in parallel system will be turned on in sequence at intervals to avoid the sudden load on the generator, thereby reducing the cost of the generator required

Generator Mode

  • Set the maximum output power of the generator when a smaller one than needed is employed to extend the battery duration time. In this case, the load is supplied by both the generator and battery

LBS Synchronization

  • Synchronize the output of the two independent UPS systems (Single unit or parallel) even when the two systems are operating on different modes (Bypass/Inverter) or on battery

Multi-protection

  • Self-diagnosis function will take place before start-up for safety
  • Multi-protection: AC input under/over voltage, overload, short-circuit, over-current, over bus voltage, over- temperature, fan failure, auxiliary power failure, battery under voltage, battery over-charge and so on
  • In addition, the UPS is equipped with an isolation transformer at the inverter output, enhancing load protection against all abnormalities from the utility supply. It also enables the UPS to achieve high compatibility with medical and industrial environments where complex harmonic distortion is present. As a result, the reliability and stability of the UPS system are significantly improved.

EPO Function

  • A concave red EPO button with transparent cover is embodied in the LCD control panel for emergency power off

User-friendly Network Management

  • Chinese/English LCD and LED mimic diagram: Real time operation parameters and status (7-inch touch screen optional)
  • RS232 & RS485 communication ports: For local monitor with corresponding software, both can support MODBUS protocol
  • SNMP adapter (Optional): For remote monitor through network
  • Dry contacts (10-160kVA optional) for additional monitoring:
    • a) UPS on Inverter
    • b) Mains input failure
    • c) Remote EPO
    • d) Battery low voltage alarm
    • e) UPS fault
    • f) UPS alarm
    • g) UPS on battery
    • h) UPS on bypass
    • Note：d)--h) optional
