Product Description

Impulse test generator circuit 3 of Table D.1.

Type 1065S surge generator (SURGE TESTER), is a test instrument for generating surge signal and HVDC signal. This instrument is designed and manufactured according to the requirements of the latest version of GB8898-2011 (equivalent to IEC60065:2005) (IEC62368-1-2018)standard 10.1 and 14.1. It is specially used for surge test of insulation requirements for all kinds of electronic and electrical products. It is an electrical safety test instrument and equipment.
1065S surge generator is an upgraded version of 1065A. Panasonic PLC (Panasonic C14R) is used to control all the parameters and the working state of the instrument is displayed and set on the 7-inch color
touch screen. The humanized interface is easy to operate. The instrument also has overvoltage protection to ensure the safety and reliability of the instrument. The instrument has the advantages of simple operation, good performance, high reliability and reasonable price. It can be widely used in
electrical safety testing laboratory and electronic and electrical manufacturing enterprises.

Note:

1) switch S is the key component of the circuit, and its design should ensure that the effective energy consumed on flying fox or imperfect insulation is as small as possible.

2) subject component X is connected to terminals C and D. Voltage dividers R2 and R3 are optional to enable oscilloscopes connected to both ends of R3 to observe voltage waveforms at both ends of the subject assembly. The compensation of the voltage divider should ensure that the observed waveform is consistent with the tested assembly.

3) in particular, the latest board standard has removed the parallel resistance R2 from the old version of the standard
