Hioki ST5520 Insulation Tester with External I/O Output, 25 to 1,000V

Description

The Hioki ST5520 High Speed Insulation Tester is a benchtop device designed for rapid, automated insulation resistance testing on production lines. It features an external I/O output to enable seamless integration with automated systems, and a test voltage range of 25 to 1,000 V with 1 V resolution.

Key Features

• Rapid testing: The ST5520 delivers pass/fail assessments in as fast as 50 ms, making it the fastest in the industry for production lines with rapid takt times.
• External I/O and RS-232C: The standard external I/O and RS-232C interfaces allow for integration with automated production line equipment and PCs for automated control and data capture. The status of I/O signals can be checked on the instrument's screen.
• Configurable test voltage: The test voltage is freely configurable from 25 V to 1000 V in 1 V increments to accommodate various components and evolving safety standards, such as those for batteries.
• Contact check function: This feature prevents errors caused by poor contact with the device under test and can be done through a 4-wire or comparator method.
• Short-circuit check function: Before insulation testing, a low voltage (2 to 4 V DC) is applied to check for micro-shorting.
• Quick residual voltage discharge: The time it takes to discharge residual voltage after testing has been significantly reduced, which improves takt time.
• Comparator function: Provides PASS/FAIL judgments with an audible signal and LED indicators based on freely set upper and lower limits.
• Panel Save/Load function: Stores up to 10 measurement conditions in internal memory for quick recall
