Residual Voltage Tester

ZJ-SY2000W
Customized processing can be made according to requirements
The residual voltage tester, also known as the residual voltage tester, is designed according to the national standards GB9706.1-2020 "Medical Electrical Equipment Part 1: General Requirements for Basic Safety and Essential Performance" and GB4706.1-2005 "Safety of Household and Similar Electrical Appliances Part 1: Safety Requirements": "Equipment connected to the power supply network with a plug must be designed to have a voltage between each power pin and between each power pin and the device housing 1s after the plug is unplugged." This instrument has a sufficiently high test impedance and uses a simulated plug-out method to disconnect the equipment from the grid voltage at the peak state. It is used for residual/residual voltage testing of electrical equipment such as ME electrical equipment, active medical devices, and household appliances.

Overall Dimension

1. Power-off test when the equipment power supply voltage is at the peak value, ensuring the accuracy and consistency of the test data 2. Test input impedance 100MΩ , 20pF, meeting the impedance of LE inter-electrode and accessible capacitor residual voltage and energy test requirements 3. Multi-form testing functions: A.Residual voltage between each power pin , LN,LE,NE,L/E/N-PE B.The residual voltage between each power pin and the equipment housing C.Residual voltage and energy test of capacitors accessible outside the equipment 4. Manual/automatic conversion test. That is, the phase test between poles can be performed manually, and every two poles are tested 10 times, or the test can be performed automatically to complete the test of the combination of three poles, and each combination is tested 10 times After the test is completed, all data will be displayed on the touch screen, which is clear at a glance. 5. Automatically maintain the maximum test voltage value, and automatically alarm when the test residual voltage exceeds 60/34V.
