Aim-TTi LD400 Series Series Electronic DC Load, 0 → 400 W, 0 → 80 V, 0 → 80 A

The Aim-TTi LD400 is an inexpensive, versatile electronic load designed for evaluating and characterising a wide variety of DC power sources including batteries and solar cells as well as electronic power supply units. It has the voltage/current range, multiple operating modes and built-in transient generator to provide test solutions from the design laboratory through to the component test area. The LD400P version adds full bus remote control via USB, RS232 and LXI compliant LAN (Ethernet) interfaces.
The LD400 can operate at voltages below 500mV for currents up to 10A. At higher currents the minimum remains below 1V up to 40A and below 2V up to 80A. This low operating voltage allows the LD400 to be used in many low voltage applications for which other electronic loads may be unsuitable. The LD400 can operate at power levels up to 600W for periods of up to 1 minute. Short term loading is sufficient for many testing applications so this capability significantly increases usefulness. Maximum voltage and current are 80V and 80A with a maximum continuous power capability of 400W (plus the short term capability of 600W). An adjustable drop-out voltage can be set for testing batteries.
