Teledyne LeCroy T3EL15030xP programmable dc electronic loads are versatile test devices that feature four operating modes to provide wide ranging test capabilities. In Constant Current mode, the electronic loads will sink a constant current, regardless of the voltage at the device terminals. Its Constant Voltage mode causes a constant voltage to appear at its terminals. In Constant Resistance mode, the electronic load will behave as a fixed ohm value and will linearly change the current according to the input voltage. The Constant Power mode allows a fixed power to be dissipated in the load. Transient testing allows switching between two different load values at up to 25kHz to test the dynamic characteristics of a dc source or DUT (Device Under Test).

Instruments have a 3.5″ TFT-LCD display, a user friendly interface and excellent performance specifications. Unit features an input range of 150V/30A @ 200W while the T3EL150303P version has an input range of 150V/30A @ 300 W.
