1.0Scope
This specification describes the requirements for an
2.0General Operation
Under normal operating conditions, the UPS's rectifier converts alternating current (AC power) to direct current (DC power), which is required for the system's inverter and battery charger. The charger supplies regulated DC power to keep the batteries constantly charged. The inverter uses pulse width modulation (PWM) that fully utilizes the characteristics of
2.1Performance Standards
The UPS shall be designed with the applicable sections of UL, CUL, and ISO 9001 14001. The UPS shall have UL and CUL listing.
3.0General
3.1Materials
All materials used are of new manufacture using the latest technology and should not have been in prior service except for specified factory testing. IGBT's
3.2Components
All functioning components are solid state with no moving parts.
3.3Installation
The installation of the UPS must comply with the UPS manufacturer's recommendations that will be supplied before delivery of the UPS. Local electrical codes and the National Electric Code must be complied with. All wiring must comply exactly with what is specified.
3.4Assembly
The UPS shall be delivered fully assembled and be fully functional.
4.0System Theory and Operation
4.1Theory
AC input from the utility system is converted into DC power chopper. The stepped up DC power is then converted to AC power by the inverter. The output voltage waveform of the inverter will be the pulse voltage waveform modulated by the PWM control using the 14 kHz switching frequency sinewave. The
