1. power requirements for equipment:
Input voltage: single AC220V + 10%
Frequency: 50/60Hz
Phase number: single item three wire system (L-N-PE)
Voltage resolution: 1V
The output voltage waveform resolution is less than 5%.
2. causes of electrostatic discharge:
The causes of ESD include friction, contact and separation, induction and conduction, etc. However, IEC 61000-4-2 mainly describes the low-temperature conditions, through friction and other factors, so that the volume of people tired of static electricity, when people with static electricity in contact with the process of equipment, may produce ESD. 1.3. Test Objective:
Electrostatic discharge (ESD) phenomena are simulated: under low humidity conditions, the charged human body directly touches the equipment discharging, resulting in the impact on the equipment (direct discharge); and when touching the adjacent equipment when discharging on the equipment of concern (indirect discharge).

7. experimental configuration: standard electrostatic discharge experiment environment ESD-DESK
Electrostatic discharge test table is a special device designed for electrostatic discharge test. It meets the IEC 61000-4-2 and GB/T17626.2 standards. It can also be used for the immunity test of pulse groups and attenuated oscillatory waves.
Standard electrostatic discharge test table specification:
Desktop equipment
(1) test bench (1600 x 800 x 800mm)
Reference floor (2700 x 1800 x 1.5mm)
(3) vertical coupling plate (500 x 500 x 1.5mm)
(4) horizontal coupling plate (1600 x 800 x 1.5mm)
Insulating liner
A cable with resistance (470K *2)
This set of test configuration is specially designed for electrostatic discharge test, which meets the requirements of IEC 61000-4-2 and GB/T17626.2 standards. It plays an important role in improving the repeatability and comparability of electrostatic discharge test. According to the different equipments tested, there are two configurations in ESD test, one is table type and the other is floor type. ESD-DESK is a combination of two configurations. The configuration can also be applied to the immunity test of pulse group and damped oscillation wave.
