R&D strength: 35 doctors and masters in various electronic and electrical specialties, including 2 IEC members.
Total number of patents: 32. From 1994 to 2004, a total of 100 patents were obtained.
Specialization and intelligence of BENDER medical products The components of BENDER medical IT system are:
ES7 10 single-phase isolation transformer
107TD47 insulation monitor
MK2007 /MK24 18 External Alarm Display Instrument
STW2 current transformer
Internal power supply of AN450 instrument
Insulation fault location system of bending machine; On-line fault shunting;
1, applied to IT system
2. There is a ground fault in the isolated power supply system. After the insulation monitor gives an alarm, the PGH474 insulation fault evaluator sends out a test current, and the insulation fault evaluator EDS474- 12 conducts patrol inspection, so that the fault shunt can be found online.
3.EDS474- 12 insulation fault evaluator can monitor 12 branch.
Patented technology of BENDER medical t system
Ampere pulse measurement is a patented technology of Baender company, and the European patent number is EN654673B 1, which can completely meet IEC standards.
The national standard GB16895.24-2005 (IEC 60364-7 -7 10) "Building Electrical Devices Part 7-710: Requirements for Special Devices or Places-Medical Places" stipulates that:
710.413.10.5 The medical IT system shall be equipped with insulation monitors conforming to IEC6 1557-8 and meet the following requirements:
The AC internal impedance should be at least 100 kOhm;
The test voltage should not be greater than 25VDC;
Even in the case of fault, the peak value of injection current should not be greater than1ma;
