Electrical safety

Workplace safety with safe HV test enclosures

The safety of people takes centre stage here. We solve this with our safety test hood.

It is suitable for testing candidates with

  • voltages above 60V DC or
  • above 25V AC or
  • currents above 3mA AC
  • and can in turn emit potentially dangerous voltages for the operator.

High-voltage test enclosures

The HV test enclosure, developed by us in accordance with EN50191 standard (erection and operation of fixed and temporary electrical test installations), is designed for testing large quantities in ongoing production. The ergonomic design ensures fatigue-free operation even during repetitive work sequences. Equipped with all safety-relevant functions, such as safety switch and locking of the hood cover during the test sequence, the operator is optimally protected at all times.

Features and benefits of the LXinstruments HV test hoods:

  • Swivelling, transparent hood made of sturdy, highly insulating plastic
  • Built-in safety switch to lock the hood and release the test routine
  • Generously dimensioned wiring space in the base for easy installation of interfaces
  • Prepared openings for the passage of connectors and wiring
  • Effortless opening and closing of the hood by means of precisely adjusted gas springs
  • Hinges with ball bearings designed for high cycle rates in production
  • Available in 600 mm and 900 mm

You will find the whole range of test hoods we carry clearly arranged in our Shop.

HV test hoods with integrated multifunctional safety tester

The HV test hood according to Performance Level e (ISO 13849-1), developed by us according to the EN50191 standard (erection and operation of fixed and temporary electrical test installations), offers the highest safety for the operator.

The large test chamber is enclosed with a hood made of sturdy, highly insulating and transparent plastic. During the test, there is a clear view of the test specimen. A signal light visually indicates safe opening when the light is “green”. “Red light” symbolises danger, the hood cannot be opened due to the safety interlock. The safety switch also ensures that the hood cannot be opened during the test. This means that the test hood fulfils all the required specifications for compulsory contact protection.

When the hood is closed, the integrated computer starts the stored test sequence. The complete test procedure can be followed on the monitor.

Features and advantages of the LXinstruments HV test hood with integrated safety tester:

  • Swivelling, transparent hood made of sturdy, highly insulating plastic.
  • Optimum safety for the operator due to forced contact protection
  • Built-in safety-approved limit switch for locking the hood
  • After closing the hood, the test routine can optionally be started automatically
  • Optical display of the current test status
  • Computer with test software and monitor integrated in the system
  • Full network connectivity | Remote maintenance possible | User management
  • Scanning of any 1D and 2D barcodes
  • Safety box: Additional safety circuit for performance level PL e in accordance with DIN EN ISO 13849
  • Easily exchangeable adapter plates for holding the specimen
  • Individual selection of the test device according to customer specifications

Various test enclosure models with integrated safety tester can be found in the Shop.
