The EST-300 next-generation Hipot tester combines industry-leading compact size with
unbeatable performance. This new series economically integrates AC, DC withstand, and
insulation resistance into a single solution. The Hipot tester is highly portable and fits readily in
any spatially limited testing environment. The EST-300 series provides a robust set of features
that includes high output rating, ARC detection, ramp-high, charge-low, and fast discharge to
enhance overall testing eciency and safety by preventing the common errors and detecting
any dielectric breakdowns during tests on the DUT. The interconnecting function allows
expansion with a ground bond tester, oering a more complete testing system for added
safety.
Features
Thinner, Lighter and Safer
• Designed with the dimensions of piece of A4 paper, it is extremely compact in size for
operational flexibility.
• The tester fully integrates AC/DC withstand, and insulation resistance testing features
into a single solution.
• Weighing only 5.5 kg, it is one of the lightest 3-in-1 Hipot testers available on the market,
delivering extreme portability to the manufacturing floor.
• The EST-300 series is a world-class reliable safety tester certified by TUV (TUV EN
61326-1).
Eciency in Every Detail
• Ramp-high and charge-low functions
increase testing eciency by
eliminating common misjudgment
errors from the DUT’s test results that
can occur during current overshoots
and faulty connections.
• EEC-exclusive patented fast discharge
function helps the DUT eciently
released excess electricity within 50ms
to ensure maximum safety for
operators.
• Unmatched quality assurance with ARC detection capability eliminates poor gap spacing
that can cause dielectric breakdowns
• Future-proof your safety testing with expandable interconnecting capability to a ground
bond testing machine for more complete testing.
