EDS-250-300 Datasheet
Electro-Metric's Electrostatic Discharge (ESD) Simulation products simulate in a known and repeatable way the "static electricity" effects that we have all experienced by walking across a woolen or nylon carpet in the winter time and then touching an object such as a metal door knob or our office word processor table.

The EDS-250 Electrostatic Discharge Simulator consists of the following:

1. Model EDS-250/300 control unit

2. Either/both DC/PD probe



The EDS-300 is designed to simulate furniture and personnel discharge and is capable of direct and indirect voltage discharge ESD testing.Voltage is stored in the EDS-300 vanes, acting as a 150 pF distributed capacitance, and released into an object through the use of probes. The vane geometry was selected for several reasons:

  • It is less sensitive to the presence of nearby capacitive bodies
  • The charge is spread over a larger surface area
  • The vertical edges to which the discharge probe is clamped allow adjustment to different heights without altering the discharge circuit
Electro-Metrics EDS-250-300 Features
  • Electro-Metrics® Electrostatic Discharge Simulators are designed to meet existing and proposed standards
  • Common control unit (250/300)
  • Generates repeatable, fast risetime, high voltage waveforms
  • Continuously variable output to 25 kV
  • Simulates human and inanimate object waveforms
  • Simulates the four types of failure-related discharges
  • Pulse probe current injection - no air discharge, therefore, repeatable, consistent results may be anticipated
  • DC probe to meet IEC 801-2 and other air discharge needs when required
  • The pulse counter selector permits automatic test termination by means of settings made prior to test mode
  • Each probe can be used in both positive and negative polarity conditions
  • Pulse unit trigger control provides quicker and more manageable operation
  • Voltage cut-off switch for safety
  • Interchangeable tips (R&C&C for DD series, R only for PD series
