Modular UPS 20/25/30K

Introduction 

AF9900 series is an intelligent modular UPS 3 phase input and 3 phase output, 20~300KVA，which adopts online double conversion design and is based on DSP full digital control to provide stable and uninterrupted power supply for important loads. It can eliminate "power pollution" such as surge, instantaneous high voltage, instantaneous low voltage, wire noise and frequency deviation on the mains, and provide customers with high-efficiency and high-power density power supply guarantee. 

Application 

It is widely used in various industries such as government, finance, communications, education, transportation, meteorology, radio and television, industrial and commercial taxation, medical care, energy and electricity, etc.

Feature

●DSP fully digital control, rectification, inversion, charging, discharging and other power conversion links are all digitally controlled.

●All parts of the UPS architecture are digitally controlled. The UPS has excellent performance indicators, high system stability, self-protection and fault diagnosis capabilities, and avoids the risks of analog device failure, making the control system more stable and reliable.

●Equipped with a 10-inch LCD large color screen (touch screen) with rich information.

●Extreme power density design, 20K/25K/30k module is only 2U, easy to install, space-saving and easy to maintain .

●Supports optional 30A charging module to ensure reliable charging under ultra-long delay, and the application scenarios are more diversified.

●It has the function of manual or automatic transferring between equalizing and floating charge and the battery test function button. It has the function of setting the equalizing and floating charge voltage and current. It has the function of setting the battery charging voltage temperature compensation.

●The number of sections can be selected according to user needs, from 32 sections to 44 sections (optional).

●Can support 3 UPS in parallel.

●EPO button Emergency shutdown button ; users can also connect an external EPO button and have a remote emergency shutdown (EPO) function.

●When the SNMP card is selected, remote monitoring of the UPS can be achieved.
