LEAK CURRENT HiTESTER ST5540

Leakage Current Tester According to IEC 60601-1, IEC60990, IEC60335, and other Safety Standards

SKU: ST5540 Category:

Model No. (Order Code)

ST5540 for medical-use electrical devices

Note: The photograph portrays the Japanese version of the product. Other countries’ versions of the product lack the outlet on the front panel. Note: Always use an isolation transformer when measuring leak current for medical-use electrical devices. The ST5540 does not include an isolation transformer. When measuring medical-use electrical devices, use a step-up isolation transformer or similar component operating at 110% of the rated supply voltage as the power supply for the device under test.

Description

To ensure the safe use of electrical products, electrical safety tests such as insulation resistance, withstand voltage, ground resistance, and leakage current must always be conducted. Hioki Leakage Current Testers comply with laws and standards regarding medical electrical equipment as well as non-medical electrical equipment, and can be used to measure leakage current in all types of electrical products from computers to medical equipment.

The ST5540 consists of measurement networks that simulate the human body and a high-frequency volt meter, and is also capable of switching power supply polarities and making measurements under simulated single fault conditions in equipment under test.

 

 

Key Features

• IEC 60601-1: (2005) 3rd Edition, JIS T0601-1:2012 compliant
• Complies with JIS, IEC, and UL standards governing medical- and 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
• Touch panel features simple, interactive operation
• Communications functionality and external I/O support allow automatic testing on production lines

 

 

Leak Current Measurement - Essential to Electrical Safety

Compliance with IEC 60601-1:2005 (3rd Edition) is now mandatory.
The ST5540 also complies with JIS T0601-1:2012.

The ST5540 series features an improved measuring method and dramatically faster cycle times thanks to its uninterrupted polarity switching capability. The new devices support rated currents of up to 20A, making it more than ideal for use with products built to new standards.

 

 

Of Medical Electrical Devices

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.

 

 

3157 Safety Standard for Hospital Electrical Equipment JIS T 1022:2006 Measurement

Combination of Instruments for Leak Current Testing and Safety Conductor Testing

The following are key parts of any safety inspection of electrical equipment:
•Leak current test: Measure with the ST5540 and ST5541.
•Safety conductor test (also known as a ground line resistance test or ground conductor test): Measure with the 3157.
The 3157 can also be used for conducting measurements under the JIS T 1022:2006 safety standard for hospital electrical equipment.
