The Siglent SDL1000X family of active DC loads have been designed for both benchtop and automatic/remote operation. The SDS1020X series provides for total power up to 200 Watts while the SDS1030X is rated for 300 Watts. While “X” suffix versions have a resolutions of 0.1 mV / 0.1 mA, the “X-E” versions are designed with a 1 mV / 1 mA resolution.
All models come with 4 static modes (CC/CV/CR/CP) as well as CC, CP, and CV Dynamic modes that can toggle the load at a rate up to 25 kHz (CC).
Other features include 4-wire SENSE compensation mode, external analog control, List and Program functions, and RS-232 / USB / LAN computer interfaces (GPIB module is available as an option). The 3.5″ TFT-LCD display also supports a “analog” waveform trend chart function.
