(1). First understand the necessary conditions ① The power supply voltage of the control circuit, the maximum current that can be provided; ②The voltage and current in the controlled circuit; ③ How ma...
Shunt advantage: To measure a large DC current, such as tens of amperes, or even larger, hundreds of amperes, what should I do if there is no ammeter with such a large range for current measurement? T...
Shunts are available in metal film and full metal versions. Advantages and disadvantages of metal thin film resistors: Pros: Significantly cheaper Cons: They have lower temperature coefficient perfor...
Using a shunt to measure current is a simpler and more cost-effective alternative to using a sensor for current measurement. However, shunts are precision measurement devices and many things need to b...
1. The role of the shunt It is used to expand the measuring current range of the instrument, and it is used for current limiting and current sharing sampling detection in the loop of the instrument, ...
1. How to use the shunt Select the rated voltage drop specification of the shunt according to the mV number marked on the dial of the ammeter (or current-voltage dual-purpose meter) used (75mV or 45mV...
The winding and iron core of the c-type transformer are the primary components for transmitting and converting electromagnetic energy. Keeping them workable is a concern. Statistics show that the iron...
Industrial control relays are common relays in the industry. Generally speaking, a relay is an automatic control electrical appliance that acts according to a specific input signal. There are many typ...
There are many types of relays, so how do we classify them? Here we will classify them according to the working principle, product use, external dimensions, protection features, contact loads, etc. of...
The relay that controls the original is to control the closing action by generating the minimum current for the pull-in action. Generally, in use, the given current needs to be slightly larger than th...
With the rapid development of the industry, with the development of new electric energy meters, magnetic latching relays have also ushered in rapid development. Relays have become an indispensable and...
From the perspective of structure and working principle, the magnetic latching relay is an automatic switch, and it is also a new type of relay developed in recent years. The magnetic latching relay h...
