Introducing the Hioki Leak Current HiTester ST5540
Complies with all standards (suitable for use with all networks)
Leak current parameters as defined for medical-use electrical devices include ground leak current, contact current, patient leak current, and patient measurement current. The ST5540 provides a single solution for measuring all of these leak current variants.
Complies with IEC 60601-1:2005 +A1:2012 (Ed 3.1)
In order to prevent the danger of electric shock, electrical devices use power supplies that are isolated from parts of the device that may come into contact with the body. However, it is impossible to achieve infinite insulation resistance. Some leak current always exists, and its magnitude changes as the insulation degrades over time. The LEAK CURRENT HiTESTER ST5540/ST5541 provides an easy-to-operate solution for measuring leak current in electrical devices, making it eminently suitable for use in an extensive array of applications, ranging from production lines to equipment maintenance and inspections.
Key Benefits
For medical-use electrical devices and essential to electrical safety
Compliance with IEC 60601-1:2005 Ed 3.0, JIS T 0601-1:2012
(*Starting on June 1, 2012, medical electrical equipment sold in the EU must comply). Model ST5540 comply with IEC 60601-1:2005 +A1:2012 (Ed 3.1), and IEC 62353 of 2017
Compliance with Electrical Appliances and Materials Safety Act,
JIS, IEC, and UL standards for general-use electrical devices
• Uninterrupted polarity switching function dramatically reduces cycle time
• Support for rated currents up to 20 A gives the instrument more than adequate capability for testing products designed to comply with new standards
