Auxiliary power supply: DC 12 v + / - 10%
The amount of routine: 48 hz ~ 52 hz
Output specifications: DC 0 ~ 5 v
Eight, matters needing attention
1, cables must be shielded wire, and the power cord and input line and output line must be separated.
2, using the environment should be no conductive dust and no corrosive action on metals, and damage the insulation gas exists, height is less than 2500 meters above sea level.
3, switch products factory has zero and accuracy, please do not adjust.
