Thermo Keytek Series 2000 Electrostatic Discharge Test System

Keytek 2000 Generators:

• 0 to 25 kV bipolar
• Plug-in, interchangeable discharge networks for different human body models
• Separate simulations for all six key simulation modes at discharge and its five components
• Actual air discharge, plus:
  • Current injection of standard waves
  • Discharge magnetic field
  • Discharge electric field collapse
  • Pre-discharge electric field
  • Pre-discharge corona-generated RF interference
• Programmable repetitive operation
• Interchangeable tips, ball, wedge, point, field generators

Keytek 2000 Monitors:

Digital voltage monitor measures and displays:

1. Programmed high voltage before high voltage trigger is depressed
2. Actual, measured high voltage during charge and after discharge
3. Audible beeper to indicate discharge

Keytek 2000 General Specifications:

Voltage Range:

• 1 to 25 kV with Ball Tip (and without Extender Cable EC-1)
• 1 to 20 kV with Point and Wedge Tips (DT-2, DT-3)
• 1 to 20kV with Extender Cable EC-1 and any tip

Polarity: Operator-Selectable (plus or minus).

Operating Modes: Single-shot and repetitive.

Repetition Rates: One shot per approximately 1, 3 or 10 seconds.

Built-In Digital Voltmeter:

• High Voltage Trigger On:
  • Measures and displays actual high voltage at the ESD Simulator's tip
• High Voltage Trigger Off:
  • Before tip voltage has decayed to below 300-500V, continues to measure and display tip high voltage
  • After tip voltage has decayed to below 300-500V, displays "Program Voltage" -- the voltage that will appear at the tip when the high-voltage trigger is depressed

Program Voltage Adjust: Multi-turn, long-life potentiometer, mounted in thumb-accessible position on ESD gun handle.

Discharge Ground Strap: Inductance equivalent to that of IEC-specified return, but with insulation adequate for 25kV. Length ~ 2000mm, or 6.5ft.

Normal / Slow Ramp Selector

• Slow Ramp Position: In Slow Ramp mode, for repetition rates of one shot per 3 seconds and one shot per 10 seconds, the high-voltage ramps up slowly enough to permit the digital voltmeter to display the voltage at which the simulated ESD breakdown occurs
• Normal Ramp Position: Preferred for most other work.
• Normal ( Single-Shot ) / Burst Selector: In Burst position, allows realistic simulation of multiple discharges even when the ESD tester is on a tripod or is otherwise in a fixed location

Discharge Networks

DN-1

• Energy Storage Capacitor: 150pf
• Discharge Resistor: 150ohm
