The adoption of a high-efficiency PWM switching amplifier enables stable testing.
This is a testing machine designed to conduct three types of tests based on various global safety standards: AC/DC withstand voltage and insulation resistance (IR). By adopting a high-efficiency PWM switching amplifier, it can maintain a stable output voltage even when the AC line voltage fluctuates, allowing for consistent testing. The STW-9801 is dedicated to AC withstand voltage testing, while the STW-9802 features both AC and DC withstand voltage testing functions. The STW-9803 is a model equipped with three functions: AC withstand voltage testing, DC withstand voltage testing, and insulation resistance testing, resulting in a total of three models in the lineup. Additionally, it is equipped with a sweep function, and test results are graphically displayed on the LCD panel on the front. In standalone testing, it can save up to 100 test conditions and execute them automatically. It is capable of safely and accurately conducting tests according to safety standards set by various countries, including IEC, EN, UL, CSA, GB, and JIS.
