The Aim-TTi LD400 is a 400 W electronic DC load designed for testing and characterizing a wide range of DC power sources, including batteries, solar cells, and electronic power supplies. It provides a wide operating range of 0 to 80 V and 0 to 80 A, with continuous power dissipation up to 400 W at 28 \u00b0C and up to 600 W for short periods of up to 60 seconds. The LD400 supports constant current, constant resistance, constant conductance, constant voltage, and constant power operating modes, with high-resolution level setting and a low minimum operating voltage that remains below 1 V up to 40 A. Its built-in transient generator provides variable frequency, duty cycle, and slew rate control, while a current monitor output enables waveform viewing and a variable drop-out voltage supports battery testing. A high-resolution backlit graphic LCD with soft-key control provides local operation, while analogue remote control and TTL control of on\/off and transient switching support external control. Front and rear input terminals provide flexible connection options, with front terminals rated for up to 30 A. The LD400 uses variable-speed fan cooling and a compact half-rack 3U enclosure, making it suitable for laboratory and component-level DC power-source testing.<\/p>","protected":false},"excerpt":{"rendered":"
