1. Brief introduction
1.1. Technology introduction
●
This UPS is a sophisticated piece of equipment with 16 bit Microprocessor and advanced software
programming technology, high frequency SPWM is created to control the inverter of UPS. This simplifies the
control circuit, enhances the stability of UPS, also enables the UPS to have enhanced real-time performance
that makes UPS respond the variety of external environment rapidly and insure that the control circuit is
compact and reliable.
●
Digital control technology to avoid the temperature excursion of hardware specification
●
Self-diagnoses before startup help UPS to find potential failure to avoid any losses
●
Double conversion on-line topology, which makes the UPS a pure sine wave machine with constant
frequency, constant voltage, low noise and no interruption with mains power fluctuation, it protect the user's
equipments ideally all the time.
●
No transfer time when main power fail or main power restore, meets the requirements of precision
instruments.
●
Standard bypass function
When UPS meets a fault, it can transfer to bypass seamlessly and provide alarm.
●
Advanced voltage compensation technology, makes the wide input voltage range, reducing the battery
usage, enhancing the adaptive ability against the bad mains power variation.
●
Advanced wide frequency input technology
Wide input frequency range of UPS gives UPS a good compatibility with generator under field
circumstances.
●
The advanced PFC technology on the input of UPS, improves the input power factor close to unity, raises
the power efficiency, removes the harmonic noise from UPS to utility, lowers UPS operational costs, it's
really an environmental friendly protection power supply.
●
Smart management function
Under mains power blackout, UPS would transfer to battery mode to supply power to loads, when battery
voltage is low, UPS would protect itself and shuts down automatically. When main power restores, UPS
would be turned on automatically to supply power to loads.
●
Cold start function
When there is no input, UPS can be turned on with battery pack, to meet the user's emergency needs. The
cold start function is quite strong. UPS can be cold started on full load situation.
●
Fault operation prevention function
Every button has delay function, only when you press and hold the button for a certain time, required
