Product Description

MASTECH HY3020D Linear DC Power Supply

The HY3020D variable 0 to 30 volts at 0 to 20 AMP DC power supply is of very high quality construction by Mastech. Excellent for regulated power requirements with the variable 0-30 volt 0-20 amp output. Other uses include lab, science projects or any other use where stable voltage up to 30 volts is required. For the variable output the voltage is variable from 0 to 30 volts and the current is also variable from 0 to 20 amps. The digital LED meters display the actual voltage and current within 2 percent.

Both the voltage and the amperage are adjustable with COARSE and FINE tuning controls for absolute BEST precision.
