NR8809 Charger Characteristic Tester

NR8809 Charger Characteristic Tester is a new product developed according to the relevant national requirements of the "DC Power Operation and Maintenance Regulations" integrating years of research and development results and long-term field operation experience. This device can achieve different detecting and testing of capacity chargers and battery pack capacity and can accurately and reliably test the voltage stabilization accuracy current stabilization accuracy ripple coefficient efficiency value AC input 1-25th harmonic value and discharge capacity and other parameters of the DC power supply system in the substation. At the same time it is equipped with the data analysis software which performs various analyses on the measurement data uploaded to the computer.

Product Characteristics

(1) It is a special software for DC power supply testing and analysis.
(2) Use ARM and DSP and 16M bytes of FLASH memory;
(3) The instrument uses a touch screen to make the operation simpler and more convenient
(4) The measurement data can be saved echoed or uploaded to the PC for analysis;
(5) Modular structure reasonable design and reliable operation.
(6) USB flash drive can be used to update the instrument software;
(7) Use the data analysis software of the charger characteristic tester to analyze the measurement data in detail on the PC.
(8) Large-screen LCD display full English interface man-machine dialogue operation easy to use.
(9) Fully automatic test: only need to set the relevant test parameters according to the technical indicators of the charger the device can automatically complete the functions of AC voltage adjustment load resistance parameter test automatic recording of test values and stop testing.
(10) Complete communication function with RS232 communication interface and USB interface. The data is transferred to the computer for warehousing management and long-term historical data storage and analysis can be carried out; the data can be transferred by U disk and the test can be saved edited and printed at any time.
(11) Powerful data processing function: It can display multiple measurement results and curves of the charger characteristic tester generate reports and conduct comprehensive calculation and analysis to accurately determine.
(12) Three-phase automatic numerical control voltage regulator is adopted: high output accuracy high power high voltage stability and a single current of up to 20A.
(13) Modular combined structure: The modular combined structure is small in size and light in weight which is convenient for vehicle transportation and mobile detection in various substations.
