  • The M98 series programmable electronic load uses AD+DA technology to achieve fast and high-precision measurement. The 0.1mV/0.1mA level resolution of the equipment instrument can effectively display small changes in voltage and current. The latest CR-LED test mode is added The diode conduction voltage fully simulates the working principle of the diode to truly reflect the characteristics of the LED light source, allowing the test voltage and current to reach normal and stable values to avoid traditional fixed resistance mode undervoltage and current instability or impact, thereby truly reflecting the LED driver load conditions.

    The M98 series of programmable electronic loads are widely used in product development requirements and production line testing and quality inspection requirements in LED driver, switching power supplies, power transformers, chargers, batteries and other industries.

    • The display resolution with the highest voltage of 0.0001 is suitable for more testing occasions.
    • 500kHz high-speed sampling AD, voltage and current peak-to-peak and peak-to-peak real-time measurement (Vpp/Vp+/Vp-/Ipp/Ip+/Ip-).
    • CR-LED test mode, convenient parameter setting mode is more convenient to use.
    • OCP test function, automatically acquire OCP protection points, and automatically acquire maximum power point (Pmax) and current voltage and current parameters.
    • Maximum 50kHz dynamic load frequency, current slope can be set, and voltage peak Vp+/Vp- can be measured in real time.
    • Time measurement function, which supports OVP protection point and protection time test, power start-up time/hold time test, etc.
    • Battery test mode, which can test battery endurance and capacity, and has the functions of internal resistance test and curve drawing.
    • List test mode, which can test the comprehensive parameters of power supply under various load conditions, including comparator function.
    • U disk software upgrade function, always keep the latest operating version.
    • One-button screen copying function makes it easy to save or transfer the contents displayed on the screen, and the standard USB HOST is convenient for data saving.
    • There are 100 sets of internal instruments and 500 sets of external (U disk) setting files, which can save and call setting parameters.
    • Handler and RS232C interface are standard to facilitate online operation and signal output.
    • Compatible with serial communication instructions of other mainstream manufacturers, and can be directly replaced.
