The Instek GPT-9901 HiPot Insulation Resistance Tester 5KV has 500VA Capability

Instek GPT-9901 HiPot Insulation Resistance Tester is the most economical model in Instek’s 9000 series Insulation Resistance Hipot testers. In addition, the Instek GPT-9901A is a ACV Hipot Tester performing AC withstanding tests to 5KVAC/100mA leakage current.

Instek GPT-9901 HiPot Insulation Resistance Tester meets Testing Demands of Safety Standards

Instek’s GPT-9901, a new series of safety testers with wide safety applications, is a high durability and multiple user-protection design. 

Consequently, the GPT-9901 meets a variety of safety standards including:

•  IEC
• Also, EN
• UL
• Also, CSA
• GB
• Also JIS as well as other safety-related requirements

Instek GPT-9901 HiPot Insulation Resistance Tester ~User Safety by Design

For example, Instek’s GPT-9901 uses a combination of hardware and software controls to improve user safety. Likewise, a self-check performance makes sure all the functions and operations are under normal condition upon initializing the tester. In addition, the “ Zero-Crossing Turn-On” design insures the output voltage always begins at the zero-crossing of input power’s  sinewave. Thus, this feature avoids the impact of a surge voltage output. In addition, the output voltage automatically cuts off when abnormal output voltages are present. Also, the output cuts off when attaining the upper or lower current limits during testing.

User Protection at Conclusion of Test

In addition, to protecting the operator from hazardous injury, the GPT-9901 automatically protects the user after testing. Consequently, after each test, the GPT-9901 discharges the DUT completely. This step eliminates excessive voltage that might remain on the DUT. To further ensure safety, the interlock connector  also provides second level protection to prevent inadvertent operation.

Instek GPT-9901 HiPot Insulation Resistance Tester ~ Easy to Use Design Concept

Instek’s GPT-9901 features a simple & clear panel layout, a high resolution dot matrix LCD display, and color LED indicators, thereby allowing operators to interpret measurement results easily and quickly.

Test performance management is under a high-stability voltage output with high-resolution measurement results. Furthermore, the test duration, ramp up time and upper/lower limits of the output voltage are fully-adjustable. Hence, this feature accommodates a wide variety of safety tests with accurate measurement results.
