The Chroma 19020 dielectric withstand test instrument from MDL Technologies can boost productivity by measuring Hipot leakage current on ten channels at the same time. The new instrument can be used to carry out AC/DC Hipot and insulation resistance safety tests in a production environment, producing significant savings in speed and space.
On a production line the items to be tested are often close together, with a risk of being damaged if high voltage is applied to adjacent components at the same time. The 19020 eliminates this risk by synchronising its high voltage outputs.
A master / slave link enables up to ten units to be controlled, making 100 channels in total. The unit also includes powerful flashover and open / short circuit check functions.
Also available from MDL is the twin-port Chroma 19032, a five-in-one production safety analyser that can perform AC/DC Hipot, insulation resistance, grounding resistance and dynamic leakage current testing. Suitable for testing medical equipment, it accepts a range of plug-in cards with different human body equivalent circuits as specified in the safety directives.
Another dielectric withstand test instrument, and one of the smallest on the market, is the Chroma 19070. This can perform either AC Hipot tests only or AC / DC / IR Hipot testing with insulation resistance measurements to 5kV AC and 6kV DC, with a resolution of 1V.
“We can also supply higher voltage Hipot testers up to 20kV DC,” said MDL managing director Mark Lucock.
