Note: This product adopts the most advanced DC servo motor loading and deceleration mechanism to ensure the latest requirements of the latest standard for extremely slow speed test and extremely fast test. (Generally, the pulley mechanism has large error), the user can freely choose the boost. The rate is the only test equipment of its kind that meets the national standard requirements for the boost rate.
6, test method:
DC test: 1, constant speed boost 2, step boost 3, withstand voltage test AC test: 1, uniform speed boost 2, step boost 3, withstand voltage test Note: According to different industry standards, we can according to user requirements , according to your industry standards, to customize the special test functions required by the industry standards.
7. The overcurrent protection device should have sufficient sensitivity to ensure that the power is cut off within 0.1S when the sample is broken down.
8. Leakage current selection: 1-100 mA can be set freely by computer software.
9. This instrument adopts the advanced non-contact original uniform pressure regulation mode to eliminate the mechanical transmission boosting mode of similar products.
10. Support short-circuit test requirements in a short time. (Other similar products do not have this feature)
11. Five samples can be made at the same time in one test. (The same kind of product can only do one sample in one test)
12, voltage measurement error: ≤ 1.5%
13, the test voltage is continuously adjustable: 0-100 KV
14, pressure time setting: 0-6 hours (can be continuously set by software)
