Programmable DC electronic loads offers wide-ranging test capabilities

Saelig Company now offers the Teledyne LeCroy T3EL15030xP Programmable DC Electronic Loads. These versatile test devices offer four operating modes to give wide-ranging test capabilities. In Constant Current mode, the electronic loads will sink a constant current, whatever the voltage at the device terminals. Its Constant Voltage mode produces a constant voltage to appear at its terminals. In Constant Resistance mode, the electronic load will act as a fixed Ohm value and will linearly change the current depending on the input voltage. The Constant Power mode provides a fixed power to be dissipated in the load. Transient testing enables switching between two different load values at up to 25kHz to test the dynamic characteristics of a DC source or DUT.

The instruments feature a 3.5" TFT-LCD display, a user-friendly interface and superior performance specifications. The T3EL150302P model highlights an input range of 150V/30A @ 200W while the T3EL150303P version provides an input range of 150V/30A @ 300W. The T3EL15030xP series gives a measurement resolution of 1mV/1mA and adjustable current rise times from 0.001A/us to 2.5A/us.

For remote communication and control, the T3EL15030xP series incorporates RS232/USB/LAN interfaces.

The T3EL15030xP loads can give insight into battery performance by analysing the discharge characteristics of the DUT. The device provides three-stop conditions for the discharge test: voltage, capacity or time. The discharge process is instantly terminated if the stop conditions are met, affording more control over the test termination and safety throughout critical tests. During the test process, the battery voltage, discharge current, discharge time and discharged ability displays are clearly presented on the LCD panel. This series provides stability over an extensive range of testing applications including power, battery/handheld device design, industrial use, automotive electronics, LED lighting, and aerospace.
