DESCRIPTION

This is packed with features and at a cost that can’t be beat!! It has an easy to read 4 digit LED is used to display the voltage and current values and 4 programmable storage setting.

This is a heavy duty single-channel, constant-voltage and constant-current Linear power supply with low ripple and noise, high reliability and high accuracy.

The voltage and current are continuously adjustable.

It is designed for use in labs, colleges and in production.

This unit is priced about the same as lower cost 3 digit power supplies without programmable storage!!!
