Product details
Professional Instrument Equipment and Testing Solution Supplier - JETYOO Industrial&Jianyou (Shanghai) Measuring Instrument Co., LtdFounded in 2011 by Jian JET, a product technical support engineer for Agilent (now known as KEYSIGHT), and Rong YOO, a product technical support engineer for KEITHLEY (now known as Tektronix)Characterized by technological applicationsThe agency trading company,Focused on the industrial testing industry for 16 yearsAiming to break through the old and establish the new! Fill the gap of most imported instrument and equipment manufacturers only setting up sales points in China, but with weak or no technical support, and agent distributors only specialize in sales, not professional in pre-sales technical Q&A/testing plans, and not professional in after-sales training/maintenance calibration. oursTechnical salesAll of them have a bachelor's degree or above, and have more than 10 years of experience in the testing industry. With our advanced and unique business philosophy of "relying on technology! Selling instruments!", we specialize in providing instrument equipment, testing solutions, technical training, maintenance and measurement services for Chinese users, serving the industryA company with technical engineersA technology oriented comprehensive service provider for instruments and equipment.
Japan's HIOKI ST5540 Leakage Current TesterPerformance characteristics
Leakage current measurement required in electrical safety (for medical electrical equipment and general electronic equipment)
Complies with IEC60600-1:3rd
ST5540 can be used for medical electrical equipment/general electronic equipment, in compliance with JIS/IEC/UL standards
Equipped with continuous polarity switching function, significantly reducing contact time
Rated current up to 20A, suitable for products with new standards
Dialogue box format, easy-to-use touch screen
Equipped with communication function and external I/O, it can be used for automatic inspection of production lines
When measuring the leakage current of medical electrical equipment, it is essential to use an insulated transformer. ST5540 without insulation transformer. When measuring medical electrical equipment, please use 110% of the rated power supply voltage as the power source for the tested equipment in a step-up insulated transformer.
All installed networks comply with standards
Mainly applicable standard IEC60601-1 3rd IEC60990 JIS T0601-1:2012
It also applies to standards for general electrical equipment and old medical standards.
From production line to maintenance, a reliable ST5540
The non-stop polarity switching function with a rated current of 20A and a voltage of 250V can shorten the working hours (when used with an insulation transformer). Since the polarity can be switched without cutting off the power supply of the tested object, it can smoothly proceed to the next project measurement on the maintenance site.
ST5541 affordable and applicable to electrical safety laws
Equipped with switch ports necessary for standard measurement
Equipped with ports that comply with IEC60601-1 and JIS T0601-1 for testing leakage current.
Add 110% voltage port
Equipped with an external 110% voltage port for use in medical equipment inspections.
Protective conductor current measurement function
Capable of measuring the protective conductor current specified in IEC60990, IEC60950-1, etc.
Automatic measurement function to shorten operation time
It can automatically switch power polarity or measure normal or single fault states.
Combination of leakage current test and protective conduction test
The safety inspection of electrical equipment is a necessary item. Please use the AC ground resistance tester 3157 in the protection conduction test (also known as the grounding wire resistance test or grounding conduction test)
