ESD Simulator SESD 216 | 16.5 kV
IEC / EN 61000-4-2, Ed. 3
The ESD simulator SESD 216 is suitable for carrying out EMC tests on systems and installations in accordance with the IEC / EN 61000-4-2 standard (ESD testing). Higher test levels beyond the standard limits can be set.
Two test methods are used depending on the test specimen and test setup:
Air discharge (AIR) and Contact discharge (CON)
The test probes for air and contact discharge are included in the scope of delivery! Further models for special requirements are available in our extensive range of accessories.
The large display with easy-to-read digits shows the current operating status, all selected parameters and the actual discharge voltage during air discharge. The clearly arranged keyboard and automatic programmable test sequences enable intuitive operation.
The ESD gun does not require a base unit and can be operated via an in-built rechargeable battery or mains supply. The device has a user-friendly touchscreen, ergonomic design and remote control software. The low weight and functional design, as well as optional remote control software, ensure optimum handling at an excellent price/performance ratio.
For existing devices, please note IEC 61000-4-2, Ed. 3 - the new edition for ESD tests from March 2025. Changes to calibration, cable lengths, etc. will be particularly relevant for existing devices.

Like every product from Schlöder GmbH, the ESD simulators are complemented by a powerful portfolio of accessories to complete your test stations. Appropriate accessories are available for the SESD 216 for tests in accordance with IEC 61000-4-2.
- Horizontal coupling plane (HCP) - and vertical coupling plane (VCP)
- Earth cable
- ESD verification set, 4 GHz additionally with suitable transport case
- Test Tips for ESD
- Support arm with balancer and practical suspension hooks for hanging on the balancer
- ESD table
- Silicon sheet (IEC/EN 61000-4-2), table mats for ESD test stations
- ESD remote control software
In a practical carrying case with accessories:
- 2 discharge tips (AIR/CON)
- Ground cable
- Battery charger incl. cable
The simulator operates on battery power. If the battery is empty, it can immediately be charged with the charger provided. Loading bar in the display indicates the charging status.
No change of the battery required! (According to experience replacement battery are also empty if you need them).
The simulator has a "Contact control". When testing "CON" touches the test tip the surface of the EUT. When not contacted, will be no triggering of the pulse. The display shows "No contact". This ensures that at contact discharge actually occurs a discharge.
IEC 61000-4-2 the new edition 3.0 for ESD tests - what needs to be considered?
On March 10, 2025, Edition 3.0 of IEC 61000-4-2 was made available, replacing Edition 2.0 from 2008. Due to the scope of the revision, it is not practical to list all the changes to the standard here (as PDF). These are the main changes that are relevant for the majority of our customers.
1. New pulse parameter Ip2
In order to limit the oscillation in the trailing edge of the pulse and thus ensure a more uniform and comparable load on the EUT, the new pulse parameter Ip2 has also been introduced. In addition to the already known pulse parameters such as First Peak Current, Rise Time, Current at 30ns, Current at 60 ns, the Second Peak Current (Ip2) must now also be calibrated.
Definition Ip2: second peak of the discharge current waveform (maximum current that occurs in the time frame of 10 ns to 40 ns from the time at which the current first reaches 10 % of the first peak of the discharge current)
Relevance for Schlöder devices of the SESD series:
All new devices already meet the requirements with regard to Ip2. As the pulse parameter Ip2 was not defined in the past, we recommend carrying out a factory calibration for existing devices to check whether the respective device is already within the new standard, can be adjusted accordingly or should be replaced if necessary.
2. Calibration requirement for air discharge tip
In the past, it was sufficient to calibrate the ESD generators with the contact discharge tip. In order to ensure that the specifications for the impulse curve are also met for use with the air discharge tip in the future, it is necessary to carry out a calibration at a test level of your choice for air discharge tips that contain “additional passive or electronic components”.
Relevance for Schlöder devices of the SESD series:
The air discharge tips of the current series do not contain any additional passive or electronic components. Therefore, the requirement for additional calibration does not apply here. For older series, please contact us directly, stating the device designation and serial number.
3. Earth leakage cable (Cable with bleeder resistors 2 x 470 kOhm)
For the first time, concrete length specifications for the earth leakage cable have been defined in the new edition. The cable between the horizontal coupling plate (HCP) and the ground plate (GRP) may be max. 1.5 m long. The cable between the vertical coupling plate (VCP) and the base plate (GRP) may now be up to a maximum of 3 m long. In addition, the maximum distance between the cable lug and the 470 kOhm resistor has been defined as max. 10 cm.
Relevance for Schlöder earth leakage kits:
The addition of specific information on cable length to the standard has meant that the 2 m Schlöder earth leakage kit should no longer be used for the connection between HCP and GRP. We now offer the following cable lengths:
SESD 272-1: 1.5 m length
SESD 272: 2 m length
SESD 272-3: 3 m length
4. Calibration setup
For customers with their own calibration station, it is important to know that the set-up has changed significantly. In addition to the requirement for a significantly larger vertical calibration plate (new: 1.6 m x 1.2 m), a base plate of at least 1.5 m x 1.2 m is now also prescribed. Please refer to the standard for details on the construction of the new calibration station.
5. Calibration required for battery and/or mains operation
With the new edition, it is necessary to calibrate the ESD generator in the operating mode in which it is used for the tests in accordance with section 6.3.1. For our battery-operated SESD models, we carry out the calibration in battery mode as standard. If the SESD generator is also to be used for tests in mains operation, this must be taken into account when placing the order.
Note: This list is not a complete overview of all changes in Edition 3.0 and will be updated if necessary.
Our Schlöder devices impress with the highest quality and durability at an excellent price-performance ratio. A 25-year-old ESD gun could be recalibrated, and the battery could also be replaced and returned to the customer in the laboratory.
