INSULATION TESTER ST5520 Industry's Fastest Insulation Tester Assesses in as Fast as 50ms Overview The Hioki electrical safety testers are designed for insulation resistance and voltage withstand testing of electrical devices and components according to various safety standards. The ST5520 is the fastest insulation tester in the industry, delivering pass/fail assessment in as fast as 50 ms. 25 to 1000 V test voltage with 1 V resolution. Key Features • Rapidly assess in as fast as 50 ms • Quick discharge of residual voltage • Freely configurable test voltage (set from 25 V to 1000 V, 1 V resolution) • Contact check function (prevents errors due to poor contact) • Short-circuit check function (stops potential defects from reaching the market) • Ideal for battery production lines Industry’s Fastest Testing Speed The Insulation Tester ST5520 delivers the fastest insulation resistance testing in the industry, meeting all the requirements of production lines thanks to rapid takt times. Rapidly assess in as fast as 50 ms Testing is complete in as little as 50 ms — the fastest time in the industry. This is 700 ms faster than legacy Hioki models. Quickly discharge residual voltage The post-test residual voltage discharge time has been reduced significantly compared with legacy models. As a result, when comparing an identical sample under the following conditions, a takt time improvement of 990 ms is estimated.
