2. INTRODUCTION
These Laboratory Grade Switching DC Power Supplies were built with coarse and fine output voltage and current
limiting controls.
Current limiting control with automatic crossover of constant voltage (CV) and constant current (CC) indicators make this
series ideal for research and development work in laboratories.
