A safety testing device capable of performing various tests such as dielectric strength and insulation resistance. The AC/DC dielectric strength and insulation resistance tester STW-9800 series with a transformer capacity of 200VA will be available for sale starting from late July 2015!

<Product Overview>
The STW-9800 series is a testing machine designed to conduct three types of tests: AC/DC withstand voltage and insulation resistance (IR), based on various global safety standards. By adopting a high-efficiency PWM switching amplifier, it maintains a stable output voltage even when the AC line voltage fluctuates, allowing for consistent testing.
The STW-9801 is equipped solely for AC withstand voltage testing, the STW-9802 features both AC and DC withstand voltage testing, and the STW-9803 includes all three functions: AC withstand voltage testing, DC withstand voltage testing, and insulation resistance testing, offering a total of three models. All models share a common output for AC withstand voltage testing of AC 5kV/40mA, while models capable of DC withstand voltage testing can operate up to DC 6kV. Additionally, they are equipped with a sweep function that graphically displays test results on the front panel's LCD screen.
In standalone testing, up to 100 test conditions can be saved and executed automatically. Testing can be performed safely and accurately according to safety standards established in various countries, including IEC, EN, UL, CSA, GB, and JIS.
