Leakage current tester
50uA - 50mA | ST5540
HIOKI E.E. CORPORATION
The ST5540 is a leak current tester from Hioki that conducts electrical safety test to ensure the safe operation of electrical products. This device measures insulation resistance, withstand voltage, ground resistance, and leakage current. It adheres to the standards of medical and non-medical electrical equipment testing and is suitable for leakage current in various types of electrical products like computers. Its support for rated currents up to 20 A gives the instrument more than adequate capability for testing products designed to comply with new standards.
This device comprises of measurement networks that simulate the human body and a high-frequency voltmeter. This makes it capable of switching power supply polarities and making measurements under simulated fault conditions in equipment under test.
