AC to DC 80V 9A 720W Switching Power Supply, Drive Transformer, for CNC Motor Industrial Electronic Electrical Equipment Etc. ,Voltage Consistency

Efficiency: >80%;Output adjustable voltage range: ±5% For Halogen lamps, Stepper motors, Brushless motors: 2 times the used power = the rated power of the SMPS. Not a Constant Current PSU! The output current depends on the device you connect. It 's suggested that total power consumption of the loads to be connected be not more than 80% of the rate power of product If work 24*7 hours, the power used should not exceed 40% of the rated power.
