NRZL-Z DC power supply tester can realize the detection and test of different capacity chargers and the capacity of 500A·h and below battery packs, and can accurately and reliably test the voltage stabilization accuracy, current stabilization accuracy, ripple system, discharge capacity and other parameters. This system uses the latest PC as the host, equipped with LCD monitors, micro printers and other equipment. The long-term actual operation on the spot shows that the device has the advantages of perfect function, strong anti-interference, high reliability, good transparency, simple structure, easy to carry, and full compliance with national standards.

Overview

Characteristics and Functions
(1) Fully automatic test the device completes various test functions according to the menu: voltage stability accuracy test ripple coefficient test steady current accuracy test efficiency test.
(2) Automatically test the load current DC voltage voltage regulation accuracy ripple coefficient charger efficiency and other parameters of the DC power supply.
(3) DC stability accuracy function: automatic test charging voltage load current steady current accuracy pulse peak value pulse valley value voltage average value voltage stabilization accuracy output voltage fluctuation limit value steady current accuracy and other parameters.
(4) Discharge test function. Test the whole process of discharge. After the discharge is completed describe the discharge curve according to the record.
(5) The host system adopts a new high-speed industrial PC as processor and large-scale integrated circuit (CPLD) with dynamic response time less than 100US high reliability and excellent performance.
(6) LCD 7.5-inch color screen with large screen graphics 5-and-a-half digits all English graphical interface man-machine dialogue control simple operation and convenient use.
(7) It adopts three-phase automatic NC voltage regulator with high output precision high power and high voltage stability.
(8) Use a new type of high-power power consumption device as the load with strong load capacity non-contact adjustment for output adjustment high precision small size light weight and no open flame for discharge.
(9) Load resistors are arranged in order with 8421 codes which can be arbitrarily combined to the load required by the user.
(10) Discharge alarm function: In the process of discharging if the battery terminal voltage is less than the alarm voltage the device will sound the alarm to prompt the user and display the alarm information on the interface.
(11) Automatic discharge termination function: if the terminal voltage of the battery pack is less than the termination voltage during the discharge process the program can terminate the discharge to prevent over discharge. The device will sound an alarm to prompt the user and display the alarm information on the interface.
(12) Manual discharge termination function: if the user needs to terminate the discharge during the discharge process the program can terminate the discharge by selecting the "terminate discharge" key on the interface.
(13) Clock display and timing function: realize the relationship between time and current and determine the ampere hour meter. During the discharge process the discharge current remains unchanged.
(14) Only three keys are used to complete the setting directly input numbers print on site and have RS232 and USB interfaces.
(15) Perfect host computer function realize electronic archiving report printing and output fast search of historical records and have the functions of analysis data saving comparison and fault determination.
