    Description

    The M98 series programmable DC electronic load employs advanced AD+DA conversion technology to deliver rapid, high-precision measurement capabilities. With instrument-grade resolution of 0.1mV and 0.1mA, the system effectively captures minute voltage and current fluctuations. The integrated CR-LED test mode precisely simulates diode conduction voltage characteristics, accurately replicating LED operational principles to provide true load condition representation. This methodology eliminates the voltage drops and current instability inherent in traditional fixed-resistance testing approaches.

    The M98 series programmable DC electronic loads are engineered for product development, production line testing, and quality inspection applications across multiple industries including LED drivers, switching power supplies, power transformers, battery systems, and charging equipment.
