EEC Introduces the EST-300 Series – As Compact and Versatile as Ever

New EST-300 Series Hipot Tester


  • Small and portable
  • TUV Certified

Taipei, Taiwan, 2017-10-18

TAIPEI, TAIWAN, October 19, 2017 – EEC introduces the EST-300 series, a next-generation Hipot tester delivering industry-leading compact size combined with powerful 3-in-1 performance. This new advanced Hipot tester economically integrates AC/DC withstand and insulation resistance functionality in a single solution. The EST-300 series’ compact form factor makes it the optimal choice for mobility, while also allowing it to integrate readily into any confined testing environment.

"The EST-300 series is one of the world’s smallest and lightest devices of its type. We designed it with the dimensions of a piece of A4 paper and a weight of only 5.5kg. This reduced its length by 18.3 percent and weight by 43 percent compared to the industry standard,” said Brian Chen, EEC general manager. “This is a remarkable achievement, and gives manufactures the flexibility to move and alter their work area to maximize space usage."

The EST-300’s compact size does not compromise the device’s performance or reliability. The series delivers high testing efficiencies that show in every detail. The built-in ARC detection feature — utilized by many top-tier manufactures — detects abnormal circuit shorts, preventing poor gap spacing that can cause dielectric breakdowns while enhancing quality assurance. The ramp-high and charge-low functions increase efficiency, eliminating common errors from the DUT’s test results caused by current overshoots and faulty connections.

Safety is always priority at EEC. The company’s exclusive patented fast discharge feature allows the DUT to efficiently released excess electricity within 50ms, ensuring maximum protection for operators. The EST-300 series is TÜV-certified for excellent reliability and safety for further assurance and peace of mind. The intuitive interface simplifies operation, allowing users to smoothly issue commands with the swipe of a finger, easily set up test parameters and steps, and program automation remotely via USB connection. Additionally, the EST-300 series allows expansion with a ground bond tester to create a more complete testing system.
