Product Features
As a high-performance Line-Interactive UPS (Online Interactive UPS) and UPS uninterruptible power supply, it combines home UPS and Small-office UPS advantages with the following core features:
Wide Input Voltage Range
Adapts to harsh mains voltage fluctuations, reducing battery switching frequency for extended service life—ideal for unstable power environments in home and small office settings.
Pure Sine Wave Output
Delivers high-quality pure sine wave power with THD <3% (linear load) and <6% (non-linear load), fully matching the power requirements of high-precision devices and sensitive electronics in home and small office use.
Advanced AVR (Automatic Voltage Regulation):
Automatically adjusts input voltage deviations, balancing efficiency and protection—ensuring stable 220VAC output for all load devices, a key advantage for home UPS and Small-office UPS applications.
Intelligent Charging Management
Supports fast charging (recovers to 90% capacity in 4 hours for built-in batteries) and adjustable charging current (1A/2A/4A/6A for external batteries), maximizing battery life and backup time flexibility for both UPS for home and Small-office UPS needs.
4ms Fast Transfer Time
Instantly switches between mains and battery modes under standard conditions—avoiding data corruption and equipment failure, a critical feature for home and small office electronic devices.
Multi-Level Overload Protection
100%-110% overload: audible alarm only; 110%-130% overload: auto-shutdown after 30 seconds or bypass mode switching (normal input); >130% overload: immediate shutdown or bypass mode—comprehensively safeguarding home and small office equipment.

FAQs
UPS stands for Uninterruptible Power Supply and is a device that provides a continuous supply of power to protect critical loads from power failures or fluctuations.
The main role of a UPS is to provide a backup power source to ensure that critical equipment can continue to operate when utility power is interrupted or unstable, avoiding data loss or equipment damage.
UPS is mainly divided into three types: offline, online and online interactive.
When choosing the power capacity of the UPS, you need to consider the total power demand of the load, it is usually recommended to choose a slightly larger than the total load power of the UPS to ensure sufficient standby time.
The standby time of a UPS depends on the battery capacity and load power. Standby time usually ranges from 10 minutes to several hours, and the specific needs can be determined according to the actual application scenario.
