Big DC power loads are compact
Transient operation up to 25 KHz.
Three models of the compact benchtop units range from 150 to 250 W DC electronic loads with sink current up to 60 A at wide voltage ranges up to 500 V.
With transient operation speeds up to 25 kHz and 16-bit resolution, they’re used for testing and evaluating a variety of DC sources, such as power supplies, converters, batteries, LED drivers, and photovoltaic arrays.
Measured and set parameters are viewed simultaneously with a dual-line display. Other features include adjustable current slew rates, built-in rise and fall measurement, and voltage turn-on capabilities to start and stop discharging power sources at specified voltage levels.
Standard GPIB, USB, and RS232 interfaces support USBTMC and SCPI communication protocols for remote control and programming.
And protection modes, including overvoltage, overcurrent, overpower, overtemperature and local/remote reverse voltage protection, prevent damage under test.
