The difference between one corner and two corners of PTC starter:
A corner:
1. The output current of the PTC starter in one corner is low, and it can only start the motor with low power;
2. The power of the PTC starter in one corner is low and can only work at a lower current;
3. The insulation requirement of the corner PTC starter is low, and the general voltage can reach less than 100V.
Two corners:
1. The output current of the two-corner PTC starter is large, and it can start the motor with high power;
2. The power of the two-corner PTC starter is higher and can work at higher current;
3. The insulation requirement of the two-corner PTC starter is high, and the general voltage can reach less than 200V.
