     The PSU 12.5-120 has a power range up to 1500W. The PSU 12.5-120 can be joined series for maximum 2 units or in parallel for maximum 4 units. A very useful feature for DUT protection are the CV and CC selections. CV mode works when the power supply is turned on and when the CC mode is activated the current becomes stable. To limit the current spike occurred at the threshold voltage and protect the DUT from the inrush current damage the PSU-Series is able to run under CC priority.

     Another way the PSU prevents DUT damage is with the OVP and OCP protections. Both the OVP and OCP levels can select the range of 10% to 110%, with the default level set at 110%, of the rated voltage / current of the power supply. The PSU has available at the rear panel the LabView driver. The driver is for external control of the power On/Off and the external monitoring of the power output voltage and current.

(*3) At 85 ~ 132Vac or 170 ~ 265Vac, constant load.
(*4) From No-load to Full-load, constant input voltage. Measured at the sensing point in Remote Sense.
(*5) Measure with JEITA RC-9131B (1:1) probe
(*6) Measurement frequency bandwidth is 10Hz to 20MHz.
(*7) Measurement frequency bandwidth is 5Hz to 1MHz.
(*8) From 10% to 90% of rated output voltage, with rated resistive load.
(*9) From 90% to 10% of rated output voltage, with rated resistive load.
(*10) Time for output voltage to recover within 0.5% of its rated output for a load change from 10 to 90% of its rated output current. Voltage set point from 10% to 100% of rated output.
(*11) For load voltage change, equal to the unit voltage rating, constant input voltage.
(*12) For 6V model the ripple is measured at 2 ~ 6V output voltage and full output current. For other models, the ripple is measured at 10 ~ 100% output voltage and full output current.
