1. Pure resistance high-power load This device adopts the latest high-power pure resistance load, which has the characteristics of strong load capacity, good linearity, high precision, small size and light weight. The structure adopts an integrated design, which is convenient to carry. (The national standard GB/T 19826-2005 "General Technical Conditions and Safety Requirements for DC Power Supply Equipment for Electric Power Engineering" clearly stipulates that resistive loads must be used during testing.)
2. The fully automatic tester only needs to set the relevant test parameters according to the technical indicators of the charger, and the device automatically completes the AC voltage adjustment, loading load resistance, parameter testing, automatically records the test value and stops the test;
3. It comes with a large-screen graphic LCD and a fully finished graphic interface of the printer, and the test data is displayed in real time during the test. All the charts are clear, beautiful, intuitive and convenient. The built-in printer can print test data at any time.
4. The device with dual operation mode can be tested on a single machine or connected to a computer through the RS232 interface for automatic testing by the computer. The data of the stand-alone test can be saved or uploaded to the computer for saving, displaying, editing and printing.
5. The large-capacity memory can store dozens of sets of test data of voltage stabilization accuracy, ripple coefficient and current stabilization accuracy.
6. 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.
7. The powerful compatibility function is compatible with the detection of 220V DC system or 110V DC system.
