The multifunction safety tester LG 3801F puts together all of the important test types in a single device, thus making it a real all-rounder. It is ideal for easy, inexpensive and uncomplicated safety tests by current national and international standards (IEC, EN, UL, VDE etc.)

Modern – efficient – intuitive

The LG 3801F provides maximum comfort and ease of use through the 5.7'' TFT colour 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 LG 3801F features a fully electronic generator, which provides more accurate and faster testing. 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 LG 3801F adapts to you and not vice versa!

All of these and much more!

Besides the required safety tests, a function test can also be performed with a current consumption test. With the help of our comfortable PC software, the LG 3801F can not only be controlled remotely, but it can also be extended by additional features and test steps.

With an ergonomic housing, the LG 3801F is ideal as a portable desktop device. Thanks to the safety current limitation according to EN 50191, no additional protective measures (such as a test cover or two-handed operation) are necessary for the operation.
