The HY3010D is a heavy duty LINEAR variable 0 to 30 volts at 0 to 10 AMP DC power supply is of very high quality construction by Mastech.

Excellent for regulated power requirements with the variable 0-30 volt 0-10 amp output.

Other uses include lab, science projects or any other use where stable voltage up to 30 volts is required.

Variable output the voltage is variable from 0 to 30 volts and the current is also variable from 0 to 10 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 precision.
