Rigol DL3041 450 Watt 200V 70A High Speed DC Electronic Load
The DL3041 is Rigol's new flagship high-performance, single-channel programmable DC electronic load designed for precision testing of power sources and components. Delivering up to 200 V, 70 A, and 450 W, it combines flexibility, speed, and accuracy for laboratory and production environments.
Key Points:
- Up to 200 V / 70 A / 450 W load capacity
- 30 kHz dynamic operation frequency
- Fast current slew rate - 0.001 A/μs to 5 A/μs
- Four static modes (CC, CV, CR, CP) and three dynamic modes
- Comprehensive protection: OVP, OCP, OPP, OTP, reverse voltage
- LAN-DL3, DIGITALIO-DL3, HIRES-DL3, and FREQ-DL3 included as standard
The Rigol DL3041 is a high-performance, single-channel programmable DC electronic load offering up to 200 V, 70 A, and 450 W of total power. It provides accurate, repeatable performance for the testing and characterisation of power supplies, converters, batteries, and other DC sources.
Key Features
- Wide operating range: 200 V / 70 A / 450 W
- Fast transient response up to 30 kHz
- Adjustable current slew rate up to 5 A/µs
- Static and dynamic load operation
- Built-in battery, OCP, OPP, and short-circuit test functions
- Comprehensive protection for voltage, current, power, and temperature
- 4.3-inch TFT display with real-time waveform view
- SCPI and LXI compliant for automated testing
- USB, RS232, and LAN interfaces standard; optional GPIB connectivity
- All software licences included – fully featured as standard
The DL3041 supports constant current, constant voltage, constant resistance, and constant power operating modes. Dynamic operation is available up to 30 kHz with an adjustable current slew rate from 0.001 A/µs to 5 A/µs, enabling precise simulation of transient load conditions. A list mode allows up to 512 programmable steps for automated or repetitive test sequences, with user-defined dwell times and slew rates.
Integrated application functions include battery discharge, over-current protection (OCP), and over-power protection (OPP) tests. Waveform display and data logging features provide direct visualisation and monitoring of test parameters. Comprehensive protection is built in, covering overvoltage, overcurrent, overpower, overtemperature, and reverse voltage events.
All software licences and functional options are pre-installed as standard, including LAN connectivity, digital I/O triggering, high-frequency (30 kHz) transient operation, and high-resolution readback capability. No additional activation is required.
The DL3041 supports SCPI and LXI protocols, ensuring compatibility with automated test environments.
