The Rigol DL3021A is a single-channel programmable DC electronic load engineered for power supply, battery, and device testing. Operating from 0–150 V DC at up to 40 A, it dissipates a maximum of 200 W and supports dynamic operation to 30 kHz. The instrument delivers four static modes (CC, CV, CR, CP) plus dynamic modes—continuous, pulsed, and toggled—with list editing capability up to 512 steps. Current rising speed is adjustable from 0.001 A/µs to 5 A/µs depending on input voltage. A 4.3-inch TFT LCD displays simultaneous voltage, current, and operating parameters in real time.
