1. Product introduction
NR8801 DC System Comprehensive Tester meet the state relevant requirement of the DC power supply operation and maintenance regulations it was developed and researched according to many years of research results and experiences in field operation and also was comprehensive domestic and foreign advanced technology. The device can realize the inspection and test in different capacity of the charger and battery capacity and also can accurately test the voltage regulation accuracy precision of steady flow the ripple coefficient the efficiency value AC input value 1-25 harmonic and discharge capacity of substation DC power supply system at the same time it is equipped with DC power comprehensive tester data analysis software can variously analysis the measurement data uploaded to the computer.

2. Product characteristics
(1) NR8801 is a kind of DC power test analysis of special equipment it is fully in automatic accordance with the national standard to complete ac voltage adjustment load resistance parameter test (ripple coefficient test steady flow precision test Precision of voltage regulation test etc.) automatic record test values stop testing and other functions;
(2) Strong extension function: compatible with 220 v and 110 v DC system detection;
(3) Adopt Three-phase automatic numerical control voltage regulator: the output of high precision large power high voltage stability;
(4) It uses ARM and DSP double working control and 16 M bytes of FLASH memory.
(5) Instrument use LCD touch screen all English graphics interface operating simpler and more convenient;
(6) Display test data in time during test process chart is clear intuitive and convenient;
(7) Can save echo test data or upload the test data to PC use special DC power supply comprehensive tester data analysis software to analyze detailed data chart can test save edit and print at any time;
(8) Incoming data into computer manage the warehouse long-term historical data can be saved and analyzed;
(9) Modular structure reasonable design reliable operation small volume light weight;
(10) Mass storage: can save three hundred group data of stable voltage accuracy test ripple coefficient test steady flow precision test efficiency test and Current limiting characteristics test;
(11) Has perfect communication function with RS485 communication interface and USB interface can transfer data and update instrument software trough U disk;
(12) It has automatic protection function: when the instrument detects the group or monomer battery abnormal during the testing process it can automatically terminate the test;
