Line Interactive UPS Features & Benefits

1. Excellent microprocessor control guarantees high reliablility

Machine with CPU control, all the operational parameters of UPS are controlled by the CPU, ensuring the UPS is in the best working condition. Improved the accuracy of the product parameter, ensured full compliance of product performance, the product failure rate effectively reduce.

2. Intelligent Charger

Built-in smart charger, with TOP charge type (charging type of high current at the initial, and balanced type and floating type alternating charging), shorten the battery charging time, extend the battery life, and it is suit to the areas of high rate power cut. And the users can set charging voltage and charging current by press button.

3. Wide input voltage range (110V-300V)

Interactive structural design, low frequency type program, with superior shock resistance. To satisfy the demand for different type of load, this might be widely used in household, commercial, industrial, outdoor base station.

4. Special Protection method

Prostar line interactive takes muti-level protection mode of output, which could resisit the impact effectively, and also with the short circuit protection function, which could enhance its reliability.

Power Amplifier Over Current This system is equipped with the detection of the working current of power amplifier tube. When the detection current over large, the system will automatically enter current limiting working mode, meanwhile it displays the fault code E01.
Output Short Circuit Protection When the machine is shorted circuit, the system will shut down and display fault code: E02. After removed the fault, it needs to be started manually.
Overload Protection When the charge or inverter overload, the machine will enter the protection state, and display fault code: E03, including hardware protection and software protection.
Over Temperature Protection When the machine internal temperature is too high, the machine will enter the over-temperature protection state, and display fault code: E04.
Battery Over Voltage Protection In order to avoid the wrong way battery connection or the controller and charger fault caused system damage, when the system detects that battery voltage is over high, it will automatically shut down and display fault code: E05.
Low Battery Voltage Protection To avoid excessive battery discharge, the machine will automatically shut down the system and display fault code: E06.
Phase Reverse Protection When the system detects internal phase error, it will alarm and display fault code: E07.
Low Output Voltage Protection When the system detects that the output voltage of system is over low, the inverter will automatically shut down and display fault code: E08.
Hardware Protection When entering the hardware protection, the over current protector jumps off and needs to press the over current protector button before the machine can work again.
Software Protection When entering the software protection, the machine will shut down automatically through the software control. At this time, the user needs to start the machine manually.

5. Well unattended function

While the main power is abnormal, the battery will supply power instead till low-voltage appeared, and then UPS shut down; when the main power come back, the UPS will start working automatically, and it will charge for the battery at the same time. No need to turn on the UPS manually.

6. High Efficiency and Energy Saving

When AC power is normal, the inverter is under dormant status, the main power through the built-in voltage regulator (AVR) directly to supply power to the loads, and its efficiency is as high as 98%. Therefore it is called “Green UPS” which in full compliance with the spirit of low carton.

7. Auto restart while AC is recovering

8. Pure Sine Wave Output

Line interactive UPS pure sinewave output provides maximum stability and superior compatibility with sensitive equipment. Pure sine wave power is required by some equipment power supplies and prevents others from overheating, malfunctioning or failing prematurely.

9. Boost and buck AVR for voltage stabilization

10. Cold start function

11. LCD panel for comprehensive display

Front-panel LCD signals operating mode, load level, voltage, battery charge and estimated runtimes. Supports multiple advanced user setup and operating preferences.
