Compliance West MegaPulse 746EP Surge Testing of Conformal Coatings

UL 746E Section 19 covers the necessities for conformal coatings utilized rather than electrical spacings to increase the dielectric endure voltage between traces on a printed wiring board. Paragraph 19.3 outlines a test of Voltage transient to get applied to a certain test pattern lets testing decide spacings. The Surge Generator circuit is stated in UL 746E, Figure 19.2 is contained in the MegaPulse 746E. One press of the MegaPulse 746E TRIGGER button does the test suite, described within UL 746E, Para. 19.3.

Note: Voltages 400V (+) are certified to be according to the tolerances of IEC 1180-1, Para. 6.2.2.

Provided with external interlock control. Additionally, for automated testing, the MegaPulse 746E is available with TestMinder, Compliance West's test reporting and computer control option, and also Arc Detect, which can find & report a failure in insulation. When both of these options are ordered together, the computer-generated test report’ll advise which tests passed & failed.

UL 746E Section 19 covers requirements for conformal coatings used instead of electrical spacings to increase the dielectric withstand voltage between traces on a printed-wiring board.
