Kikusui TOS5050

Features

• Tests complying with major industrial standards:
  • The tester can carry out withstanding (dielectric strength) tests on electronic devices and electronic parts in compliance with JIS, UL, CSA, BS, and other major electrical standards and ordinances.
• Transformer capacity of 500 VA:
  • The tester is equipped with a transformer, rated 500 VA.
• Rational layouts of keys and switches:
  • The keys have a slant-plane for easy viewing and convenient operation. The switch for AC/DC select and test voltage range select and the control for test voltage adjustment are installed concentrically, allowing you to operate them conveniently with two concentric knobs. For the adjustment of the pass/fail-judgment limit current and timer, dedicated increment/decrement keys are provided. These keys and switches, together with the large display easy to view, are laid out rationally and will assist you to conduct your tests accurately and efficiently.
• Large color display:
  • The tester has a large color vacuum fluorescent display. The wide viewing angle and high intensity indicates information in clearly. Various information including test conditions, instrument status, measured values, and result of pass/fail judgment are indicated using large letters and color assisting you to conduct your tests accurately and efficiently.
• Analog voltmeter and a digital voltmeter:
  • The tester is equipped with an analog voltmeter (±5 % FS) and a digital voltmeter (±1.5 % FS)--the former for quick grasp of the voltage and the latter for more accurate readout--assisting you to conduct your tests rapidly but accurately.
• Digital ammeter:
  • The digital ammeter can be used to measure the current that flows through the DUT (device under test).
• window comparator for pass/fail judgment:
  • The tester has a window comparator for pass/fail judgment with reference to both upper (U) and lower (L) criteria (cutoff current). The comparator generates a FAIL signal when the measured current that flows through the DUT is greater than the preset upper limit criterion or when it is less than the preset lower limit criterion. The L FAIL detection function contributes to improve the test reliability by detecting open-circuits and bad contacts of the test leads. The tester has a separate indicator and signal output for each type of failure (U type and L type). This allows you to immediately find out whether the failure is a withstand voltage failure or an open-circuit/bad-contact failure. You can preset the upper limit and lower limit currents (cutoff currents) independently, within the ranges shown in the following table.
• digital timer:
  • The timer allows you to preset the period during which the test voltage is to be applied to the DUT. The preset range is 0.5 to 999 seconds (in 1895 steps). When the timer function is ON, the preset period is decreased and the timer indicates the remaining period; when it is OFF, time is increased and the timer indicates the elapsed period.
• Remote control function:
  • The tester has functions for remote start/stop control operation. That is, it has a 5-pin DIN connector (for the optional remote control box or high voltage test probe) on its front panel and a 14-pin Amphenol connector on its rear panel. The remote control function, together with the status signal function, will help you conduct efficient automatic labor-saving tests.
