China Wholesale Large Industrial Online Ups Factories – High Frequency Online UPS1K-10K – Wanzheng

System Features
WZD series high-frequency online UPS adopts rack-type design, which can provide a better power supply environment for the load, which is reflected in the voltage regulation output range, frequency range, filtering of input noise, and between mains mode and battery mode. Zero conversion time, etc. WZD series 6~10kVA parallel redundancy adopts a double-conversion pure online architecture, which can block the impact of abnormal power supply on the load, and at the same time ensure the stability of the output and the possibility of safe operation of the load, which is the most effective solution to all problems. The optimal architecture design for power supply issues adopts digital control technology to realize parallel expansion and parallel redundancy functions, providing users with flexibility in power supply planning and a more secure guarantee.
The rack-mounted design can provide a better power supply environment for the load, which is reflected in the regulated output range, frequency range, filtering of input noise, and zero transition time between mains mode and battery mode. WZD series uses innovative software program control method, which not only reduces the size, but also greatly reduces the failure rate, effectively improving the safety and reliability of the power supply. It is suitable for use in various precision instrument systems, network systems, and important or demanding equipment in the power environment.

Main functions

Performance and advantages

■Automatic step-up/step-down does not require the use of batteries, and provides better usability by correcting high and low voltages.
■Intelligent battery management Get optimal battery performance, life and reliability through intelligent, precise charging technology.
■ Power conditioning protects connected loads from surges, voltage spikes, lightning, and other power disturbances.
■Temperature compensation battery charging adjusts the charging voltage according to the actual battery temperature to prolong battery life.
■Automatically restart the load after the UPS is shut down Once the utility power is restored, the connected equipment will be automatically restarted.
■Automatic self-checking Regular self-checking of batteries to ensure early detection of batteries that need to be replaced.
■Cold start capability to provide temporary battery power when the utility power stops.
■Compatible generator When using generator power, ensure a clean, uninterrupted power supply to protect equipment.

The main technical parameters

When the UPS is set to constant voltage and constant frequency mode, the output power will be derated by 40%. When the output voltage of the UPS is set to 208VAC, the output power will be derated by 10%.
■When the number of internal batteries is changed to 16-19, the machine will derate the output according to the following formula: P=PRatingX (N/20×100%)
■If the machine is installed at an altitude of more than 1000 meters, the output power will be derated by 1% for every 100m rise
