Selection of protective devices
1. The input voltage withstand range of the protection module is 18.7v ~ 30.6v;
The minimum input voltage is 22V, according to 0.85 derating requirements: 22 * 0.85 = 18.7v
The maximum input voltage is 26V, according to the requirements of secondary derating: 26 / 0.85 = 30.6v
2. The maximum output of OVP is 26V
3. The maximum output of OVC can be set to 800mA;
The maximum demand output current is 790ma, 800mA meets the jump current ≤ 5A.
4. It can bear the maximum input and output current value ≥ 941ma;
800mA/0.85=941mA。
5. The protection action time should be as fast as possible
When the circuit is abnormal, the equipment will not be damaged before the protection action is turned on.
