The Aim-TTi LD400 can operate at voltages below 500mV for currents up to 10 amps. At higher currents the fixed minimum resistance (typically better than 25mΩ) gradually raises the minimum operating voltage, but it remains below 1 volt up to 40 amps and below 2 volts up to 80 amps. This low operating voltage allows it to be used for many low voltage applications for which other electronic loads are unsuitable.


The LD400 can operate at power levels up to 600 watts for periods of up to 1 minute. Short term loading can be sufficient for many testing applications and significantly extends the usefulness of the LD400.


The LD series features electronic loads which are suitable for testing and characterising a wide variety of dc power sources. They can be used to investigate the behavior of many different types of power source such as PFCs, batteries and solar cells, as well as electronic power supply units. The wide voltage/current range, multiple operating modes and built-in transient generator give them versatility to offer test solutions from the design laboratory through to the component test area


The two operating levels for each operating mode are settable to high precision. Levels are displayed using four digit meters which provide resolution down to 1mA, 1mV and 1mW. The meters have an accuracy of 0.1% for voltage and 0.2% for current.


Some power sources, such as rechargeable batteries, can be damaged if their output voltage falls below a certain level. The LD series provides automatic protection by incorporating fully variable voltage dropout. If the voltage applied to the load falls below a preset level, the load current is rapidly reduced to zero.
