WBI224F21 adopts the principle of electromagnetic induction and hall effect to measure the AC and DC current of the power grid in real time. Using mean value conversion technology, precision constant current technology and linear temperature compensation technology, it is converted to standard DC current (Iz) output, and the characteristics of AC and DC current universal, strong overload capacity and high isolation.
Advantages:
27000 square meters non-dust workshop,
30 years' experience,
7 years' application in high speed railway,
ISO, EMC, ETC certificated.
100A-300A In Hall Effect Current Transducer Applications:
Inverter and converter;
Photovoltaic combiner box, battery management system;
Charging pile;
Wind farm monitoring, power feedback control.
30th Anniversary of Weibo Electrical Isolation Transducer
On Oct. 18th, Weibo company has invited professors from experts in automation industry and many cooperation partners to participate in celebrating the 30th anniversary of Weibo Electrical Isolation Transducer.
Mr. Ruan Ciyuan, the founder of electrical isolation transducer, reviews the birth and struggle history of Weibo electrical isolation transducer and shows gratitude to the colleagues and leaders who have worked together.
| How to choose hall effect sensor | |||||||||
| 1. Determine AC, DC or AC / DC. | |||||||||
| 2. Determine the detection current and voltage: 5mA-2000A; 100V-4000V, etc. | |||||||||
| 3. Determine the output signal: 0-5V, 0-10V, 1-5V, 1-10V, 4-20mA, 0-20mA, etc. | |||||||||
| 4. Confirm the auxiliary power: DC 12V, 24V, 9V-36V, 85V-265V (Default 24V power supply, special user specified) |
Caution:
1. Pay attention to the auxiliary power information, especially the auxiliary power grade, and polarity, other wise will damage the product.
2. Pay attention to the wire connection; wrong terminal connection will cause malfunction of the product and even damage the product;
3. Don't dismantle the product, and carry with care to avoiding bump and fall of the product;
4. There is no lightening strike prevention circuit design in this product. For out door and hazardous environment using, please add protective alternatives.
5. This product uses fire prevent ABS crust, its temperature withstand is only limited as +85℃, higher than this limitation will cause the product deformation. Please use and store carefully.
