HY3020E Mastech

The HY3020E is a lab grade regulated DC power supply with two levels of control over both current and voltage outputs (coarse and fine), which can be continuously adjustable at 0-30V DC and 0-20A. The digital LED meters display the actual voltage and current within 2 percent. Excellent for multiple regulated power requirements with 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.
