The Rigol DL3021 is a 200W single-channel programmable electronic load for power supply testing and characterization across R&D, quality control, and production environments. It operates in four load modes—Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), and Constant Power (CP)—with dynamic testing capability up to 15 kHz. The instrument accepts input signals from 0V to 150V and 0A to 40A, making it suitable for a wide range of DC source evaluation tasks.

– Key Features
Multi-mode operation handles constant-current, constant-voltage, constant-resistance, and constant-power loading scenarios. Dynamic load testing capability supports transient analysis and source stability verification at frequencies up to 15 kHz. Four-layer protection architecture prevents damage from overcurrent, overvoltage, overpower, and thermal runaway conditions. Integrated display provides immediate feedback on load parameters and system status.
– Typical Applications
Power supply qualification and burn-in testing. Battery charger and power adapter evaluation. DC-DC converter and regulated supply characterization. Dynamic load step-response and transient behavior analysis.
