Compact ESD Simulator from Teseq

Featuring ergonomic design and advanced functionality the pistol-shaped NSG 434 simulator is designed to sit comfortably in the operator’s hand, with the active operating conditions shown on the built-in LCD display. The LCD display gives the operator a clear, continuous indication of all the test parameters, the operational status of the instrument and the current function of each of the five soft-keys.

Discharge voltage is programmable across the range 200V to 8kV with a stabilised charging voltage. Pre-programmed test settings for IEC/EN 61000-4-2 may be menu selected and true air-discharge breakdown voltage is provided. The NSG 434 is battery powered, compact and lightweight, comfortable to use and simple to operate.

NSG 434’s microprocessor-based controller and multifunction keypad provide the operator with instant access to its comprehensive range of built-in functions while the LCD display continuously shows the operating

status and all user-selected test parameters. NSG 434 has its own internal, battery operated high voltage generator. An optional mains supply is available for extended test operation or for use when the battery is being charged.

In addition to the pre-programmed standard IEC pulses, users can create custom tests using single or repetitive discharges with selectable rates and manual or automatic polarity switching. The NSG 434 measures and displays true air breakdown voltages. It also detects real or valid air-discharges, thereby avoiding misleading discharge counts. This is especially important during long term tests and remote test setups.

A range of interchangeable discharge networks is available, including EN, ANSI-IEEE, and ISO. The unit comes with a standard 150 pF/330 Ω discharge network for tests to IEC/EN 61000-4-2. The NSG 435 is supplied with a range of standard accessories, including interchangeable test tips, a grounding cable and battery charger, all in a durable carrying case. There is an optional fibre optic remote control trigger for operation inside a screened room or enclosure.

Paul Dixon, Managing Director of TESEQ comments, “Our new low cost NSG 434 makes sophisticated and reliable ESD testing available to a wider range of customers. This will enable testing to take place a key development stages rather than having to carry out expensive testing at the end of a development project reducing testing costs and speeding up time to market for new products.”

The NSG 434 weighs 1.2 kg with battery and will operate over the temperature range +5 to +40°C and humidity range 20 to 80 % r.h. (non-condensing).
