1.2.1 General description
PU power supplies are wide output range, high performance switching power supplies. The PU series
is power factor corrected and operates from worldwide AC voltage range continuously. Output
voltage and current are continuously displayed and LED indicators show the complete operating
status of the power supply. The Front panel controls allow the user to set the output parameters, the
protection levels (Over-Voltage protection, Under-Voltage limit and Foldback) and preview the
settings. The rear panel includes the necessary connectors to control and monitor the power supply
operation by remote analog signals or by the built-in serial communication (RS232/485). GPIB
programming and Isolated-Analog programming/monitoring are optional.
