Humanized interface, barrier free human-machine communication
Intuitive LCD display content: UPS model, input/output voltage, frequency, load capacity, battery capacity, internal temperature, working status, working mode, and fault status.
The friendly human-machine interface design adopts Chinese LCD display, and the UPS operation status is clear at a glance, enabling zero distance communication between humans and machines.
Powerful compatibility
The wide input range and frequency range of mains power reduce the requirements of UPS for input mains power, and it is compatible with any form of power, including industrial power generation, wind power generation and other applications.
The output achieves precise zero phase synchronization with the power grid, meeting the high requirements of many devices for power supply and grid synchronization, which is conducive to the operation of rural power grids or small fuel generators when supplying power.
Intelligent communication tools for remote monitoring
RS232 and RS485 communication ports truly enable multi-purpose communication and remote monitoring. The optional dry contact interface uses passive contacts to effectively monitor the status of UPS. Through the DB9 dry node interface, the main abnormal information of UPS can be extracted through the dry node.
The optional SNMP card enables 100% remote monitoring and network management, making it easy to achieve intelligent monitoring of UPS, including close range point-to-point communication monitoring, medium range communication monitoring, and long-distance network monitoring. Real time monitoring of the operating status and parameters of UPS has been achieved; It has multiple functions such as automatic paging, sending email and voice, and remote power on/off of UPS.
Extremely environmentally friendly
Adopting green rectification and inverter technology to provide users with clean energy.
The whole machine adopts advanced anti electromagnetic interference technology, meets international standards, has good electromagnetic compatibility, and minimizes or even eliminates electromagnetic interference caused to the equipment to the greatest extent possible.

FAQ
Q: What advantages does it have compared with high-frequency single phase 220V UPS?
A:

Compared with high-frequency UPS, it has obvious advantages: ① Higher reliability: Low-frequency transformer enhances overload capacity (125% overload for 10 minutes) and anti-interference, suitable for unstable mains areas; ② Longer service life: Low-frequency components generate less heat, service life up to 8-12 years; ③ Better load compatibility: Pure sine wave output, compatible with inductive loads (small motors, air conditioners) and precision devices; ④ Stronger stability: No voltage fluctuation during switching, protecting sensitive electronics.

Q: What is the core function and working principle of single phase 220V low frequency on-line UPS?
A:

Its core function is to provide uninterrupted, stable 220V power for single-phase loads, protecting devices from power outages, voltage fluctuations, surges and harmonic interference. Working principle: Adopt double conversion (AC-DC-AC) + low-frequency transformer design. When mains is normal, it converts 220V AC to DC to charge the battery, then converts DC to stable 220V pure sine wave AC for load supply; when mains fails, it switches to battery power with 0ms transfer time, avoiding data loss or device damage.
