Dc Drive card

Dc Drive card :-

1-used to change speed of dc motor

2- change speed by analog signal or by (0-10 v)

3- the technique used is the thyristor control .this method is characterized by longlife- high temp and sudden load

4- there are :-

output	Input
0:220 dc volt	220 ac volt
0:380 dc volt	380 ac volt

5- there are 8 A , 12 A, 30 A
