Insulation tester IL 3881F

Type of device
Slide-in 19" / 4 HU

High voltage DC: Voltage range
100 – 3,000 V

High voltage DC: Current range
0 – 4 mA

Insulation DC: Voltage range
100 – 3,000 V

Insulation DC: Measuring range
500 kΩ – 1.5 GΩ

0 – 500 mA

Besides the insulation test, the insulation tester IL 3881F also includes a hipot and continuity test, thus making it a real all-rounder. It is ideal for simple, inexpensive and easy safety tests by national and international standards (IEC, EN, UL, VDE etc.)

Modern – convenient – flexible

The IL 3881F provides maximum comfort and ease of use through the 5.7" TFT color display built-in by default. Thanks to the personalised test programs – a fully automatic test plan can also be created. The DUT must therefore be connected only once – time-consuming replugging is a matter of the past!

Always flexible and ready for use at anytime

The IL 3881F features a fully electronic generator, which provides more accurate and faster testing. Due to 4-wire measurement technology, there is a separate repeat measurement of the test voltage, which ensures that the DUT is contacted properly. Thanks to the numerous interfaces, you will be spoiled for choice in terms of the control: be it via USB, Ethernet / LAN, RS 232 or 24V interface – the IL 3881F adapts to you and not vice versa!

All of these and much more!

With the help of our comfortable PC software, the IL 3881F can not only be controlled remotely, but it can also be extended by additional features and test steps.

With its classic size of 19" / 4 HU, IL 3881F is ideally suited for direct integration into a system cabinet. With the slide-in enclosure available as an accessory, it can also be easily used as a desktop device. Thanks to the safety current limitation, no additional protective measures (such as a DUT enclosure or two-handed operation) are necessary for the operation.
