The HY3020D variable dc power supply 0 to 30 volts at 0 to 20 AMP is of very high quality construction by Mastech.

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.

MASTECH HY3020D VARIABLE LINEAR DC POWER SUPPLY is 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.

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