Instek GPT-9903 Hipot IR Safety Tester

Product Description

Instek GPT-9903 5KVAC-6KVDC-50.00GΩ(IR) 500VA Hipot Safety Tester

The Instek GPT-9903 features capabilities for performing ACV Withstanding, DCV Withstanding and Insulation Resistance (IR) tests. Instek’s new GPT-9904 500VA Hipot Safety Tester features capabilities for performing ACV Withstanding, DCV Withstanding, Insulation Resistance (IR) and Ground Bond (GB) tests.Instek’s GPT-9902A features capabilities for performing ACV Withstanding and DCV Withstanding tests while the GPT-9901 is an ACV only model.

Powerful Pulse Width Modulated (PWM) Amplifier

The high-efficiency PWM amplifier is the muscular core of GPT-9900 platform design to impede the influence from the voltage fluctuation of input AC source. The output voltage is automatically cut off (within 150μs) upon the detection of an abnormal output voltage or a trip of current limits during test to protect the operator from hazardous injury. The GPT-9900 series automatically discharges the Device Under Test (DUT) after each test to eliminate excessive voltage that remains on the DUT.

Easy to Use Design Concept

Following a tidy and easy-to-use design concept, the GPT-9900 series is equipped with a simple & clear panel layout, a high resolution dot matrix LCD display, and color LED indicators, allowing operators to interpret measurement results easily and quickly. In the role as the complement of 200VA safety testers, the GPT-9900 series is designed upon a 500VA output platform to enhance all major test functions, including AC withstanding (AC 5kV/100mA), DC withstanding (DC 6kV/20mA), insulation resistance (DC 50V ~ 1000V/50GΩ max.) and ground bond (AC 32A max./650mΩ max.) tests, with high-power measurement capabilities. Further more, the test duration, ramp up time and upper/lower limits of the output voltage are fully-adjustable to accommodate a wide variety of safety tests with accurate measurement results. The “Sweep” function of the GPT-9900 series is able to display the test results point by point all through the testing period to form a trace graph. This graphic display performs the characteristic verification of a DUT through observing the parameter response to the changes of the applied voltage or current or testing time. On the graph a movable marker is available to get the parameter reading on the specific point of user’s interest.
