The GW Instek GPT-9804 is an electrical safety test meter that does AC/DC withstanding, insulation resistance and grounded chassis check tests for products that will be UL or CE certified. I'd like to buy one of these for our production line and will pick this model for sure if there are any LabVIEW drivers already created for it. Download gwgdm8351, a LabVIEW USB,Serial Plug and Play (project-style) instrument driver for a Digital Multimeter from goodwill, model(s): 8351. Find instrument drivers that are available for this instrument for use in LabVIEW, LabWindows/CVI, or Measurement Studio.

The PSW-Series is a single-output multi-range programmable switching DC Power Supply covering a power range up to 1080W. This series of products include fifteen models with the combination of 30V, 80V, 160V, 250V, and 800V rated voltages and 360W, 720W and 1080W maximum output powers. The multi-range feature allows the flexible and efficient configuration of voltage and current within the rated power range. As the PSW-Series can be connected in series for maximum 2 units or in parallel for maximum 3 units, the capability of connecting multiple PSW units for higher voltage or higher current output provides a broad coverage of applications. With the flexibility of multi-range power utilization and series/parallel connection, the PSW Series significantly reduces the user’s investment for various power supply products to accommodate the projects with different power requirements.


The CV/CC priority selection of the PSW-Series is a very useful feature for DUT protection. The conventional power supply normally operates under CV mode when the power output is turned on. This could bring a high inrush current to the capacitive load or current-intensive load at the power output-on stage. Taking the I-V curve verification of LED as an example, it becomes a very challenging task to perform this measurement using a conventional power supply. With LED connected to a power supply under CV mode as the initial setting, when the power output is turned on and the voltage rises to the LED forward voltage, the current will suddenly peak up and exceed the preset value of current limit. Upon detecting this high current, the power supply starts the transition from CV mode to CC mode. Though the current becomes stable after the CC mode is activated, the current spike occurred at the CV and CC crossover point may possibly damage the DUT. At the power output-on stage, the PSW-Series is able to run under CC priority to limit the current spike occurred at the threshold voltage and therefore protect DUT from the inrush current damage.

The adjustable slew rate of the PSW-Series allows user to set for either output voltage or output current a specific rise time at the low to high level transition, and a specific fall time at the high to low level transition. This facilitates the characteristic verification of a DUT during voltage or current level changes with controllable slew rates. The manufacturing tests of lighting device or large capacitor during power output-on are mostly associated with the occurrence of high surge current, which can greatly reduce the life time of the DUT. To prevent inrush current from damaging current-intensive devices, a smooth and slow voltage transition during power on-off can significantly reduce the spike current and protect the device from high current damage.

The OVP and OCP are provided with the PSW-Series. Both OVP and OCP levels can be selected, with default level set at 110%, of the rated voltage/current of the power supply. When any of the protection level is tripped, the power output will be switched off to protect the DUT. The PSW-Series provides USB Host/Device and LAN interfaces as standard and GPIB-USB adaptor, RS232-USB as optional. The LabView driver and the Data Logging PC software are supported on all the available interfaces. An analog control/monitoring connector is also available on the rear panel for external control of power On/Off and external monitoring of power output Voltage and Current.

A Solid Foundation for Reliable, Safe and Practical Safety Compliance Testing

GW Instek is launching to the market a new series of safety tester (hi-pot tester/hipot 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.

Gw Instek Driver Manual

Targeting user’s protections, the GPT-9800 series uses a combination of hardware and software controls to improve safety: A self-check is performed to make sure all the functions and operations are under normal condition each time when the tester is turned on; the Zero Crossing Turn-On design imposes the output voltage to always begin at the zero crossing of a sine wave to avoid the impact of surge voltage output; and the output voltage is automatically cut off (within 150μs) when abnormal output voltages have been detected or when the upper or lower current limits have been reached during testing. To protect operator from hazardous injury, the GPT-9800 Series automatically discharges the DUT after test (within 200ms) each time to eliminate excessive voltage that remains on the DUT. To further ensure safety, the interlock connector can also be used as double protections to prevent inadvertent operation.

The GPT-9800 Series, equipped with a simple & clear panel layout, a high resolution dot matrix LCD display, and color LED indicators, allows operators to interpret measurement results easily and quickly. All major test functions, including AC withstanding (AC 5kV/40mA), DC withstanding (DC 6kV/10mA), insulation resistance (DC 50V ~ 1000V) and ground bond (AC 30A max.) tests, are performed under a high-stability voltage output with high-resolution measurement results. 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.

Other functions and features of the GPT-9800 include: open circuit detection for ground bond testing to get correct measurement result with confidence; 100 sets of memory to save panel settings, which can be recalled for single test individually or for automatic tests in sequence; a remote output on-off terminal in the front panel and a signal I/O port in the rear panel provided as the means for remote start/stop control of the safety tester; RS-232C, USB and GPIB (optional) interfaces available for PC remote control and test result logging.
