The LD400 is an inexpensive 400 watt electronic load which is suitable for testing and characterising a wide variety of dc power sources.

LD400 – DC Electronic Load – TTi

Its wide voltage/current range, multiple operating modes and built-in transient generator give it the versatility to offer test solutions from the design laboratory through to the component test area.

The LD400 can operate at voltages below 500mV for currents up to 10 amps. At higher currents the fixed minimum resistance (typically better than 25milliOhms) gradually raises the minimum operating voltage, but it remains below 1 volt up to 40 amps and below 2 volts up to 80 amps.
