LeCroy T3PS20051P – Programmable High-precision DC Power Supply (20V / 5A / 100W) – Single Output, Variable 20 V

The LeCroy T3PS20051P is a single-output programmable DC power supply delivering 100 W across a 20 V / 5 A output range. Built for precision electronic testing and device characterization, it combines high-accuracy voltage and current control with fast transient response, making it suitable for both bench and automated test environments. The instrument features voltage setting and measurement accuracy of 0.03%, current setting accuracy of 0.05%, and output noise below 1.2 mVrms. Transient response completes in less than 100 µs. Adjustable slew rates, remote sensing capability, and selectable CV/CC priority with overshoot prevention support demanding load conditions. A 2.4-inch TFT-LCD display provides real-time monitoring and front-panel control.
