The DL3000 is a programmable DC electronic load for testing supplies, batteries and converters: 200 W (DL3021/A), 350 W (DL3031/A) or 450 W (DL3041), up to 150 V (200 V on the DL3041) and 40 to 70 A. It runs constant current, voltage, resistance and power modes, plus continuous, pulsed and toggled dynamic modes up to 30 kHz on the A models and the DL3041.
Built-in tests cover battery discharge, over-current and over-power trips, short circuit and lists of up to 512 steps. Readback resolution goes down to 0.1 mV/0.1 mA, and RS-232, USB and LAN are all standard (GPIB via a USB module).
