It adopts advanced DSP digital control technology, effectively improving product performance and system reliability, and achieving higher power density integration and miniaturization

Applied to small computer rooms, business halls, laboratories, servers, storage devices, office terminals, broadband access, precision instruments, automation equipment, etc

intelligent management

Equipped with fault self diagnosis and self-protection functions, the fault information is clear at a glance, and maintenance work is easy and fast.

Adopting an automatic float charging switching charging design.

Provide RS232/SNMP monitoring interface, monitoring software with power event recording and analysis functions, multiple networking solutions, support TCP/IP protocol, and enable remote monitoring and management.

stable and reliable

Based on DSP fully digital control technology, the control circuit is simplified, resulting in higher flexibility and reliability of the circuit.

Integrating short circuit, overload, overheating, output overvoltage and undervoltage protection, and wave by wave current limiting technology, the system operates more stably.

The design margin of power devices is large, and the system operation is more reliable.

green and environmentally friendly

Built in EMC filter and dual surge protection ensure safer power consumption for loads.

The high input power factor causes minimal pollution to the power grid.

PFC input power factor correction technology reduces input harmonic currents and minimizes pollution to the power grid.

Compliant with ROHS requirements and meeting the high electromagnetic compatibility standard ClassB.

High Efficiency and Energy Saving

Pure online dual transformation design, isolating and filtering out various harmonics and faults in the power grid.

Provide the best power supply quality for the load.

Equipped with ECO economic working mode selection function, reducing energy consumption and achieving an operating efficiency of over 94%.

Intelligent fan speed regulation reduces noise and saves energy consumption.

High power density design, small footprint, and higher overall operating efficiency.

Flexible and applicable

Rack and tower compatible design, allowing for flexible installation of 19 inch racks and towers.

The 220V, 50Hz/60Hz power standard can be flexibly set by the panel.

The LCD display method varies depending on whether it is mounted on a random rack or tower, allowing for free rotation and convenient viewing for users.

Simply increase the backup time by adding battery modules.

special design

The output power factor is 0.9, which is 13% higher than the load capacity of ordinary models.

The ultra wide voltage/frequency input range of the power grid facilitates the connection of fuel generators, avoids frequent battery discharge, and extends battery life.

DC cold start function, which can be powered on by the battery for convenient emergency backup power supply.

The on/off function of the combination key method avoids user misoperation.

Intelligent monitoring accessories selection

SNMP card: Remote monitoring and management based on TCP/IP protocol.

AS400 card: dry contact signal output transmission card.

USB card: monitoring and management based on single machine communication.

RS485 card: 485 communication based on MODBUS protocol.

intelligent monitoring

This system can achieve remote centralized monitoring of UPS working status, with functions such as telemetry, remote signaling, remote control, and automatic alarm. The management methods can be adjusted according to the actual situation in production and operation, which also reduces the burden on the on duty personnel on the front line of production, completely solves the production mode of manual inspection and manual log recording in the past, and is completely automated by computers 24/7. At the same time, it also avoids safety hazards caused by human factors.

50/60Hz power system adaptive

Automatically identify and adapt to 50Hz/60Hz power systems to meet different power system requirements.

Variable frequency function

Supports 50Hz input/60Hz output or 60Hz input/50Hz output frequency conversion mode to meet the special needs of users.

Panel setting function

ECO setting.

The EOD point of the battery can be flexibly set by the panel to maximize battery utilization.

The output voltage is set to 208V/220V/230V/240V.
