Product No: M9822A
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.
