Compared with similar products, there are still significant differences in the current series resonance of the circuit resistance tester
1. The perfect combination of high current and lightweight, for example: while ensuring a current output of 200A, the overall weight of the machine is only about 5.5kg, while other companies’ similar products, such as the 100A model, need to reach 15kg.
2. The ability to continuously output high current for a long time, while some similar products can only output high current instantaneously, known as “pulse type” power supplies, has a huge difference in the ability to penetrate the oxide film of switch contacts.
3. Numerical control constant current series resonance type, current output selected by software, no mechanical adjustment device, stable and reliable.
