This series of 200Watts LABORATORY GRADE SWITCHING DC POWER SUPPLIES are built with precision coarse and fine output voltage and current limiting controls. The OVP (output over voltage protection) protects voltage sensitive load by instant shutting down the supply when output voltage is in excessive to the set voltage due to line surge or otherwise. Current limiting control with automatic cross over of constant voltage (CV) and constant current (CC) mode makes this series ideal for R&D work in laboratory situations.
