The Model EST802 ESD Generator (ESD Simulator or ESD gun) can be continuous adjusted electrostatic discharge pulses voltage from 0 to ±20KV in both air and contact discharge operations. Exceeding industry ESD test standards requiring pulse voltages of 8kv (contact)/15 kV(air). Basic model is supplied with 150 pF/330 ohm network in compliance with IEC/EN 61000-4-2,IEC 1000-4-2 and IEC 801-2 / 1991, and other optional extra discharge networks is available 

Features of the Model EST802 ESD Generator
* The output voltage of contact discharge (CD) and air discharge ( AD) is 0 ~ ±20 KV, convenient, replaceable contact discharge/ air discharge tip.
* Digital display, high precision (better than 1%), high stability (0.5%), high distinguish (10V).  
* Output voltage is continuous adjustable. It can freely choose the value & electrode of tested voltage.
* This ESD Generator is the lightest static discharge gun in the world.
* The key part's voltage durability is 10KV~20KV better than international and national criterion required. It can completely ensure the safety of human and devices.
* With optional discharge mode, one time, once/second, 20 times/second and other modes are available. We can also set the discharge frequency according to customer's requirements.
* With multi-function, main body can act as high precision (1%), high stability (less than 0.1%), and continuous adjustable high voltage power supply. It's used for calibrating static voltage meter and other experiment.
