INTRODUCTION
2.1 General
LEONICS NB S-series/NPB S-series UPS is a True On-line Double conversion uninterruptible power supply which is the highest quality power protection system to protect against all utility power problems. With LED and LCD displays, user can view the UPS operating status anytime.
True On-Line Double conversion system has two operation steps. First, it convert alternative current (AC) to direct current (DC) Some of the direct current will flow to charge the battery to be backup power and the rest will invert to alternative current and then supply to load. If the AC input is disconnected, the UPS will invert the direct current from battery to alternative current and supply to load. UPS will supply AC power to load continuously.
2.2 Features
-True On-line pure sine wave
-Microprocessor controller
-Stable output frequency (Crystal control)
-Over current and short circuit protection
-Built-in output isolation transformer
-Load safe battery test (available in NBP S-series only)
- EMI/RFI and power line noise protection
-Automatic bypass overload protection
-Automatic bypass transfer switch (zero transfer time)
- DC start (AC start without battery (option))
-Manual self-test
- RS-232 communication port
-Sealed lead acid maintenance free battery
- LED indicator and LCD display

2.3.1
2.3.2
When utility power and loads are normal
Above diagram shows how UPS works when utility power (AC line) is normal and UPS has less than100% load. UPS converts utility power from alternative current (AC) to direct current (DC) at RECTIFIER. Some of the DC power flow to charge battery to be backup power and the rest flow directly to INVERTER to invert power to high quality and stable AC power. Then, supply to load.
When utility power is normal but overload.
- 4 -
Above diagram shows how UPS works when utility power is normal and UPS has more than 100%
load. UPS converts utility power at RECTIFIER / CHARGER section to charge battery only. The power supplied to load directly is from utility line.
2.3.3
When utility power fail but loads are normal
Above diagram shows how UPS works when utility power fails such as blackout, brownout, under
voltage, over voltage or frequency fault and UPS has less than 100% load. UPS draws backup power from battery to invert to AC power and continuously supplies to load.
Use maintenance bypass switch when UPS is malfunction (option)
2.3.4
Above diagram shows how system works when UPS is malfunction. User is allow to temporary run
the system by turning the manual bypass switch from position A to B or at BYPASS position. All loads will get power supplied directly from utility line. Then, contact us or our nearest service center.
