Item Code: TOS-3200

The Leakage Current Tester TOS-3200 is designed to perform leakage current (touch current and protective conductor current) tests on general electrical equipment but not medical electrical equipment. It enables you to conduct tests that conform to the requirements of the applicable IEC, UL, JIS, and other standards, as well as the Electrical Appliance and Material Safety Law. The memory in the main unit stores the 51 types of test conditions laid down in the IEC/JIS standards for information technology equipment, household electrical appliances, audio, video electronic apparatus, luminaires, motor-operated electric tools, and electrical equipment for measurement and control and in the Electrical Appliance and Material Safety Law, thereby enabling you to conduct standard tests with simple panel operation. 

Features:

  • Measures leakage current in 3 operation modes: Touch Current (TC), Protective Conductor Current (PCC), and METER mode

  • Eight types of measuring circuit networks are incorporated in the tester for measuring the touch current of general electrical apparatuses

  • DC/RMC: 30µA to 30mA (DC/RMS: 50µA to 90mA). Possible to measure DC/RMS/PEAK, realizing the "true root-mean-square value" with 30 mA as the maximum RMS

  • User-friendly operability

  • Possible to choose between Independent and Automatic Testing

  • 51 types of preset safety standard tests

  • Function for controlling the calibration expiration limits

  • The utility software (Freeware) can be downloaded. That enables you writing and reading TOS-3200 test condition, reading test result, test control (execution and stop), reading measured leakage current value, and other functions.

Item Code: TOS-5300-Series

The TOS-5300 Series is a series of test instruments used in Hipot (withstanding voltage) tests and insulation resistance tests, two of the four tests regarded as necessary for ensuring the safety of electrical products. With an output of 5 kV/100 mA (AC) and 6 kV/10 mA (DC), the series can be used in Hipot (withstanding voltage) & insulation resistance testing of electronic equipment and electronic parts, based on the requirements of IEC, EN, UL, VDE, JIS, and other international safety standards and the Electrical Appliance and Material Safety Law. Also, the test voltage stability is improved with the adoption of a newly developed switching amplifier. Since the output voltage can be kept constant even when the AC line voltage or frequency changes, consistent testing can be performed, even when the power supply environment is in an unstable region. The TOS-5300 is also equipped with a number of features that are capable of meeting a variety of test needs. It is a new low-cost standard model that provides thorough operability, reliability and safety.

Features:

  • Reducing the tact time: Increasing productivity. Capable of setting the test time from 0.1s

  • Highly stable: Newly developed, high-efficiency PWM switching amplifier. Providing a stable output of high voltage without being affected by AC line variation. Ensure the user to perform highly reliable testing with confidence, even in regions with large voltage variations. (Input voltage fluctuation rate: ±0.3%)

  • Rise/Fall Time control function of the applied voltage: Equipped with a Rise time/Fall time control function. Prevents from an excessive stress applied to the EUT or for standard tests.

  • Pursuing usability and safety: All new design of the control panel and output terminals. Eliminates the projected components of output terminals, and equips with a new type of the LOW terminal. Pursuing the improvement of safety and a convenience in production line, such as providing the protection cover for the front panel.

  • Supporting the world-wide input voltage: Usable globally. Usable in any country without changing the input power supply. Selectable output frequency. The instrument not rely on the input power environment. Supplying the stable test voltage with 50/60 Hz frequencies.

  • Lightweight and compact design: Increasing your work efficiency. Weighs Approx. 15 kg, 40% lighter than conventional models.
