# PRO300-33T Sorensen DC Power Supply Used

**Additional Features:**

-   Voltage: 0-300V
-   Current: 0-33A
-   Power: 10 kW
-   Input: 480 VAC, 50/60 Hz, three phase input
-   Regulation: 0.1% line and load regulation (max.)
-   SCR Preregulator Topology
-   Unique circuit prevents load burn-out should remote programming lines open
-   OVP shutdown standard
-   SCR Crowbar
-   Remote control functions: voltage, current, OVP shutdown, external meter/indicator driver
-   No programming resistors in contact with output, avoids high voltage problems with programming components
-   Fast programming speed: 100 to 150 ms typical
-   Rear panel connector features: AC control, shutdown, voltage set, OVP set, local/remote current meter, remote voltage meter, OVP indication, thermal indication and remote sense

The PRO300-33T 10 kW programmable power supply meets the sophisticated control and packaging requirements of high power test and measurement applications. These supplies have SCR preregulation. Optional internal IEEE-488/RS 232 capability for various programming and readback functions with 12-bit resolution and accuracy is available. Other features include outputs for remote voltage and current readings, remote OVP programming and remote shutdown. The PRO300-33T yields 80% efficiencies at full power with good regulation (<0.1%) and RMS ripple as low as 20 mV.
