A Solid Foundation for Reliable, Safe and Practical Safety Compliance
GW Instek is launching to the market a new series of safety tester
with high durability and multiple user-protection design. The GPT-9800 Series look to meet a variety of safety
standards such as IEC, EN, UL, CSA, GB, JIS and other safety-related requirements for the safety tests of electronic
products and components.
A total of 4 safety testers in the GPT-9800 Series, namely GPT-9804, GPT-9803, GPT-9802 and GPT-9801, are available
for various applications. The GPT-9804 is a 4-in-1 model capable of performing AC withstanding, DC withstanding,
insulation resistance and ground bond tests. The GPT-9803 is a 3-in-1 model capable of performing AC withstanding,
DC withstanding as well as insulation resistance tests. The GPT-9802 is capable of performing both AC and DC
withstanding tests, whereas the GPT-9801 is able to perform AC withstanding test. The series of safety tester
is built upon a high-efficiency PWM amplifier platform with AC 200VA maximum output capacity to impede the influence
from the voltage fluctuation of the input AC source. This ensures a stable voltage supply for all the tests
of the GPT-9800 Series.
High Efficiency and High Stability Output
Unlike the conventional safety tester design that uses variable voltage
transformer and class AB amplifier to provide testing voltage, the GPT-9800 Series, carrying a high-efficiency
PWM amplifier design, generates output source up to 98% efficiency. This greatly reduces the amount of power
loss to heat and therefore lowers the temperature within the cabinet of the GPT-9800 Series. The suppression
of temperature rise during heavy-duty operations of the tester significantly increases its reliability and service
lifetime. In addition, as PWM amplifier is comparatively more resistant to the fluctuations of input power voltage,
a stable high-voltage output with less than 1% regulation is provided by the GPT-9800 Series to perform precision
tests of the DUT.
High Accuracy and High Resolution Testing Performance
In order to provide high accuracy testing for production test, regulation
compliance, and characteristic verification, the withstanding test voltage (AC 5kV/DC 6kV) of the GPT-9800 Series
can be adjusted in 2V steps, while the current measurement can be done with 1μA resolution and ±(1.5% + 30μA)
accuracy to enable small leakage current measurements of the products or the components. In addition, the test
voltage of insulation resistance of the GPT-9800 Series can be adjusted in 50V steps within the DC output range
from 50V to 1000V, carrying a measurement accuracy of ±(10% of reading +1 MΩ) at full scale (2000MΩ/9500MΩ).
This provides the flexibility for performing I.R. measurements under variable levels of applied voltage. As
the majority of safety regulations need an AC source for ground bond testing, the GPT-9800 Series provides 6Vac
voltage (open circuit) and 3A~30Aac current for ground bond test, meeting IEC 60601-1 requirements. Furthermore,
open circuit detection (via SOURCE H, SENSE H and SOURCE L terminals) for ground bond testing is also provided
to check whether the test apparatus is properly connected before the start of a test. This is to ensure the
ground bond test is done accurately without any unnoticeable misconnection of the test leads and the test terminals.
With these capabilities, the user is able to perform various safety tests and verifications with high flexibility,
accuracy and confidence.
