The Teledyne LeCroy T3EL150303P is a single-channel programmable DC electronic load rated at 300 W, designed for testing and validating DC power sources across a wide operating envelope. This benchtop instrument accepts input voltages from 0 V to 150 V and currents up to 30 A, with minimum operating points of 0.15 V at 5 A and 0.9 V at 30 A. The 3.5-inch TFT-LCD display provides real-time monitoring with 1 mV voltage and 1 mA current measurement resolution.
