Features: Complete digital control 10 mV / 1 mA high accuracy and resolution Low noise and ripple CV / CC constant voltage and current modes Arbitrary set protection, OCP and OVP with high reliability 5 sets of parameters can be stored inside Output switch control Power-off memory function Keyboard lock function to prevent operators from misusing Easily alternative to the traditional digital-display power supplies Accurately generating the required voltage and current KA series power supplies provide the output voltage from 30V to 60V, and the resolution with 10V and 10mA. Professional power supply design; intuitionistic operation More than one power supplies can be superimposed with parallel connection 5 kinds of programmable preset and set Just press the buttons RECALL and SAVE; then the stored data can be recalled and the users' settings can be saved respectively. Avoiding the damage of the loads The cut off values of Over Voltage Protection and Over Current Protection can be set. And the buttons can be locked by the keyboard lock function to prevent the users from improper operation so that some undesired results appear in the key tests.
