• Quasi-Squared Wave
• Output Waveform.
• Miniaturization and low operating noise.
• High efficiency transformer.
• LCD display for system monitoring.
• Short term non-interruption transfer and automactic
  recovery operations.

• Easy equipment check and setting via front panel
• Supply voltage stabilization using ferro-resonant transformer.
• Battery cell voltage sensing function (option card).
• "Output Expansion Module (PIM)" allows load capacity to be
  distributed and set.
• "NMS" module can be installed
• It is compatible with other boxes.

• Advantages of using a quasi square wave transformer
- Using a Ferro-Resonant Transformer, it is possible to prevent damage of a load device caused by a transient voltage, a brain surge, etc.,
  which flows into the power source due to the supersaturation operation of the transformer.

• HFC network UPS layout and electrical wiring diagram

- The internal layout of the HFC network UPS is shown in the left figure, and each part is modularized and easy to maintain.
- There is an LED on the bottom of the box to indicate the status of the equipment, so external check is easy.
- Input / output of wiring are made through the lower part of the box.
- The box adopts a sealed structure.
- The wiring diagram in the box is as shown below, and it has separate power supply line for maintenance and emergency operation
   such as emergency generator input.
- Main parts are made of connector connection structure for uninterrupted maintenance of output power.
