Instek GPT-9903 HiPot Safety Tester 5KV 500VA Capability

The Instek GPT-9903 HiPot Safety Tester is one of the premier model in Instek’s 9000 series of Insulation Resistance Hipot testers. In addition, the Instek GPT-9903 3-in-1 model’s capability performs AC withstanding, DC withstanding and insulation resistance tests.

Also, As a Bonus Major Test Functions Include:

• AC 5kV/40mA withstanding
• DC DC 6kV/10mA withstanding
• Insulation DC 50V ~ 1000V resistance

Instek GPT-9903 HiPot Safety Tester meets Testing Demands of Safety Standards

Instek’s GPT-9903, a new series of safety testers with wide safety applications, is a high durability and multiple user-protection design. Consequently, the GPT-9903 meets a variety of safety standards including IEC, EN, UL, CSA, GB, JIS and other safety-related requirements.

Instek GPT-9903 HiPot Safety Tester ~User Safety by Design

For example, Instek’s GPT-9903 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 each time when initializing the tester. In addition, the “ Zero Crossing Turn-On” design requires that the output voltage always begin at the zero crossing of input power’s  sine wave. Thus, this feature avoids the impact of a surge voltage output. In addition, the output voltage is automatically cut off (within 150μs) when abnormal output voltages are detected. Also, the output is cutoff 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-9903 automatically protects the user after testing. Consequently, after each test, the GPT-9903 discharges the DUT each time to eliminate excessive voltage that might remain on the DUT. To further ensure safety, the interlock connector can also be used as second level protection to prevent inadvertent operation.

Instek GPT-9903 HiPot Safety Tester ~ Easy to Use Design Concept

Instek’s GPT-9903 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.

Major Test Functions Include:

• AC 5kV/40mA withstanding
• DC DC 6kV/10mA withstanding
• Insulation DC 50V ~ 1000V resistance

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.
