Electric Screw Driver, Rated Voltage : 20-30DCV

Low-voltage large-scale electric screw driver
low-voltage dc motor + power supply of frequency conversion and stabilized voltage=utility and more durable
features:
1.frequency conversion and stabilzed voltage supply;
2.low resistance, anti-static;
3.large range of optional torsion;
4.large range of adjustable rev;
5.stable torque force, convenient maintenance.
low-voltage dc motor drive,motor with long service life, high safe coefficient through low voltage screw driving,convenient maintenance and low cost.
double power supply of input ac (100-200v) and output (20-30v) ,frequency conversion & constant voltage ,more stable torque force, temperature and rev.
thecapacity of power supply is increased to 4.5a, which improves the locking power of the screw driver,assures the nornal performance of each item of the low-voltage screw driver.
segmentless speed-adjusting +soft start-up+stable voltage +little volume and light weight. The multifunction exceeds the requirement of screwing quality.\
the combination of spring crane ,power supply, and electric screw driver can be used together or separately, with mobility and operability and is more flexible and convenient.
