DTL3A Datasheet PDF - DATEL Data Acquisition products

DATEL’s new DTL3A is a digitally controlled, optically isolated, serial-input electronic load that offers high compliance voltage and unprecedented control over low-level currents. The DTL3A is essentially a computer controlled current source that sinks currents from 0 to 2 Amps, at loading voltages from 2.5 to 200 Volts, up to a maximum power of 100 Watts. The DTL3A accepts a serialized, 12-bit, CMOS/TTL digital input word, optically isolates (500Vdc) the data, latches it, and presents it to an on-board, 12-bit, digital-to-analog (D/A) converter. The D/A output drives a near-ideal (10MΩ output impedance), voltage-controlled current source.
