Instek GPT-9904 HiPot Insulation Resistance Ground Bond Tester meets Testing Demands of Safety Standards

Instek’s GPT-9904 Hipot testers satisfies a wide variety of safety applications. Also, it features a high durability, multiple user-protection design. Consequently, GPT-9904 meets a variety of safety standards including IEC, EN, UL, CSA, GB, JIS and other safety-related requirements.

Safety by Design ~ Instek GPT-9904 HiPot Insulation Resistance Ground Bond Tester  

Instek’s GPT-9904 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 initializing the tester. In addition, the “ Zero-Crossing- Turn-On” requires the output voltage to begin at the zero crossing of input power’s  waveform. Thus, this feature avoids the impact of a surge voltage output. In addition, the output voltage reduces to zero automatically when abnormal output voltages are present. Also, the output is cutoff when attaining the upper or lower current limits during testing.

In addition to protecting the operator from hazardous injury, the GPT-9904 automatically protects the user after testing. Consequently, after each test, the GPT-9904 discharges any test voltage that might remain on DUT.  To further ensure safety, the interlock connector operates as second level protection to prevent inadvertent operation.

Instek GPT-9904 HiPot Insulation Resistance Ground Bond Tester ~ Easy to Use Design Concept

Instek’s GPT-9904 features a simple & clear panel layout, a high resolution dot matrix LCD display, and color LED indicators. Additionally, this feature  allows operators to interpret measurement results easily and quickly.

Major Test Functions Include:

• AC 5kV/40mA withstanding
