  • Exceptional Precision & High Resolution for Demanding Applications
    This programmable DC electronic load delivers industry-leading resolution of 1mV/10mV for voltage and 1mA/10mA for current, allowing you to capture subtle variations in power supply regulation and transient responses. The CV accuracy of ±(0.05%+0.02%FS) and CC accuracy of ±(0.05%+0.05%FS) ensure that your test results are trustworthy for certification, validation, and quality control. Whether you are testing low-voltage logic circuits or high-voltage motor drives, the fine resolution enables precise characterization of efficiency, dropout, and load regulation. The 3803M variant extends voltage input to 500V, making it an ideal programmable DC electronic load for high-voltage battery packs, telecom rectifiers, and industrial power supplies. Combined with 10mW power readback resolution, you can confidently measure standby power consumption and energy losses that matter in modern green designs.
  • Flexible Operating Modes for Comprehensive Testing Scenarios
    Unlike simple resistive loads, this instrument offers 12 distinct modes to simulate real-world conditions. Constant Current (CC), Constant Voltage (CV), Constant Resistance (CR), and Constant Power (CP) cover basic load requirements, while combined modes like CC+CV and CR+CV allow you to emulate battery charging profiles or LED driver behaviors. The dynamic test mode (with T1/T2 settable from 50ms to 60s) evaluates how power supplies respond to load transients – critical for ensuring stability in microprocessor systems and motor controllers. The list mode can simulate complex, multi-step load changes over time, while the scan mode automatically sweeps through a range to test output continuity. As a versatile programmable DC electronic load, it adapts to your specific test plan, eliminating the need for multiple dedicated testers and streamlining your lab bench.
  • Professional Battery Discharge & LED Testing Functions
    Battery manufacturers and users will appreciate the dedicated battery test function, which supports CC and CR discharge modes with a maximum capacity readback of 9999Ah. You can set cutoff voltages and timers to automatically terminate tests, generating reliable data for cycle life analysis and capacity verification. The LED test mode simulates the unique loading characteristics of LED drivers, preventing oscillations that often occur with standard resistive loads. This makes this programmable DC electronic load equally valuable for lighting engineers, power adapter designers, and energy storage system integrators. The clear TFT display shows real-time discharge curves and accumulated Ah values, enabling instant go/no-go decisions during production testing.
  • Robust Protection & Safety Features for Peace of Mind
    Testing high-power devices carries inherent risks, but this load is engineered with multiple safety layers. Overvoltage protection (user-settable thresholds like >21V or >155V/510V), overcurrent protection (>3.1A or up to 42A), and overpower protection (410W or 210W) automatically shut down the input to prevent damage to both the load and the device under test. Overtemperature protection triggers at 85°C, and the intelligent fan speed control reduces noise during low-power operation while ensuring adequate cooling at full load. The input polarity reverse connection prompt alerts you before incorrect wiring causes harm. With these built-in safeguards, this programmable DC electronic load gives you confidence to test even prototype power supplies without fear of catastrophic failures.
  • Intuitive User Interface & Data Management
    The 2.8-inch color TFT LCD (320×240) presents voltage, current, power, and status information in a clean, easy-to-read layout. The combination of a numeric keypad and rotary encoder allows fast parameter entry and fine adjustments, significantly reducing setup time compared to single-encoder designs. The keylock function prevents accidental changes during long-duration tests – a thoughtful touch for burn-in and aging applications. Data storage retains settings even after power loss, so you don't have to reconfigure the load for recurring tests. For automated systems, remote control via USB, RS-232 (optional), or 485 (optional) makes this programmable DC electronic load fully integrable into ATE (Automated Test Equipment) environments, supporting SCPI commands for seamless programming.
  • Dual-Channel Option (3824M) for Parallel or Independent Testing
    The 3824M model stands out with dual independent channels, each rated at 200W (20A, 150V), allowing you to test two power supplies simultaneously or combine channels for higher current (up to 40A) or power (400W) in parallel mode. This flexibility doubles testing throughput in production lines and saves valuable bench space compared to two separate loads. It is an ideal programmable DC electronic load for multi-output power adapters, battery management systems with separate charge/discharge paths, or redundant power architectures. The independent readback per channel provides clear visibility into each output's performance.
  • Rugged Build, Compact Footprint & Complete Accessories
    Despite its powerful capabilities, this series maintains a compact benchtop size of 90×190×300mm and weighs approximately 3.8kg, making it portable enough for field labs and service centers. The pale gray body resists fingerprints and scratches, while the standard accessories – power cord, two fuses, manual, and certificate – ensure you can start testing immediately. The built-in buzzer provides audible alerts for test completion or fault conditions, so you can multitask without constantly monitoring the screen. For engineers who demand precision, versatility, and safety, this programmable DC electronic load series delivers exceptional value, reducing the need for multiple instruments while enhancing test accuracy and repeatability across a wide range of power electronics applications.
