Seaward has developed a range of electrical safety testers designed to help manufacturers of electrical and electronic products to comply with all required performance and safety standards.

The new Clare HAL series provides a range of dedicated and all-in-one electrical safety testers that can be used in standalone applications or as part of integrated production-line systems.

Based on the HAL Mark 1 range, the extended series now includes five testers to enable users to meet all common international safety standards quickly and effectively.

The new series includes the HAL 100 dedicated 40A ground bond tester, the HAL 101 AC/DC hipot and DC insulation tester, the HAL 102 hipot tester with a scanner switching matrix, the HAL 103 combined hipot, ground bond and insulation tester and the flagship HAL 104, which is an electrical safety tester that also provides load, leakage and power-factor measurement.

By combining electrical safety and functional testing, the HAL 104 is particularly suitable for production situations where high-resolution performance measurements are important, such as LED products in low-energy lighting applications and photovoltaic (PV) solar panels.

All instruments in the new range feature a simple user interface and fully isolated outputs to provide safe operation.

The testers can be operated manually with the push of a front fascia button and also offer an automatic test option with a series of preconfigured test specifications.

In addition, various input and output ports allow test activation to be initiated though selectable sensors and enclosure interlocks or via remote PCs or PLC systems for large automated production systems.

The instruments can also be interfaced with a variety of accessories including barcode scanners and label printers.

Each new HAL includes a large, clear, full graphic display for the presentation of test information in a numerical or analogue format.

As traceability is such an important aspect of all production-line procedures, an internal memory allows the storage and downloading of up to 6,000 test results.

By providing a flexible range of electrical safety testing instrumentation, the new range has been designed to give all electrical and electronic goods manufacturers the levels of control and traceability needed to suit their own test requirements.
