Small Home Online UPS 3kVA

Small home online UPS 3kVA:
1. Digital Design
Adopted DSP control technology and digital design topology, C UPS can be operated and maintained more conveniently.
2. Reversed Polarity N and L wire Detection Function.
Reversed Polarity of wiring or input protective grounding-wire is abnormal, at this point the indicators will alarm blink cyclically.
3. A Real Green-environmental Protection Power.
"The commercial power input factor correction technique is used. Under the Normal mode, UPS achieves real energy-saving
By inputting harmonic less than 10% and frequency power factor above 99%. "
4. Direct Current Cold Start Function
When battery input voltage in the range of normal voltage. By pressing the ON button, UPS can start up normally.
5. Alarm High-low Battery Input Voltage Protection Function
"UPS alarms in case of the battery input voltage too high or too low. As the battery continuously go up or down out of the normal range,
UPS will alarm and stop input or transfer to bypass mode to ensure the battery life and protect user equipment"
6. Communication and Monitoring Function
"Equipped with standard RS232 interface and intelligent slot. The UPS Operating and electrical parameters can be monitored through
Standard RS232. Through intelligent slot status interface the intelligent control can be flexibly configured according to different
Applications to users, for instance, stem node, network monitoring, text message"
7. Output High- Low Voltage Protection
"When UPS output is greater than the output over-voltage protection point or less than the output low-voltage protection point,
It will shut off inverter output to bypass and automatically alarm. After all the fault removed, users can restart the machine normally. "
8. Output Short Circuit Protection
"When the Inverter output overloaded and short circuit, UPS will stop output and alarm and blink continuously.
After the troubleshooting, it can restart normally. "
9. Overloaded Protection Function
