Issues to consider when selecting a Power Relay:
1. First understand the necessary conditions
1 control circuit power supply voltage five steps, the maximum current that can be provided;
2 voltage and current in the circuit being controlled;
3 The controlled circuit needs several sets and what forms of contacts. When a power relay is selected, the power supply voltage of the general control circuit can be used as the basis for selection. The control circuit should be able to provide sufficient operating current to the power relay, otherwise the power relay pull-in is unstable.
2. After consulting the relevant data to determine the conditions of use, you can find the relevant information and find out the model and specification number of the power relay that requires five steps. If there is a power relay on hand, you can check whether it can be used according to the data. Finally consider whether the size is appropriate.
3. Pay attention to the volume of the appliance. If it is used for general electrical appliances, in addition to considering the chassis volume, small power relays mainly consider the layout of the circuit board. For small appliances, such as toys and remote controls, ultra-small power relays should be used.
