High resolution and accuracy for level setting The LD400P adds full bus remote control via USB, RS-232, GPIB and Built-in transient generator with variable slew LAN (Ethernet) interfaces. Current monitor output for waveform viewing Variable drop-out voltage for battery testing Low minimum operating voltage High resolution backlit graphic LCD with soft key control The LD400 can operate at voltages below 500mV for currents up to 10 amps. At higher currents the fixed minimum resistance (typically Analog remote control of levels and TTL control of on/off better than 25mW) gradually raises the minimum operating voltage, and transient switching but it remains below 1 volt up to 40 amps and below 2 volts up to Front and rear input terminals (front terminals 30A max.) 80 amps. Full bus control via USB, RS232, GPIB and LXI compliant This low operating voltage allows it to be used for many low voltage LAN interfaces (LD400P) applications for which other electronic loads are unsuitable. 600 watts intermittent power 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.
