Multifunctional Modes & Customization: The MDL150 offers three sophisticated operation modes: Constant Current Mode, Constant Power Mode, and Constant Resistance Mode, enabling precise control and customization for various testing scenarios. The ability to set and adjust parameters like overvoltage, overcurrent, and overpower protecting value ensures custom operation within specified limits. High-Precise Measurement & Calibration: With a maximum load voltage of 150V, load current of 20A, and load power of 150W (60W above 120 V), providing highly accurate measurements. The open calibration feature for voltage and current and the zeroing load calibration ensures accurate readings and improved reliability over time. User-Friendly Design & Enhanced Usability: The 2.4-inch color screen offers clear visualization of data and settings, complemented by intuitive controls for brightness adjustment, screen sleep settings, and language switching between English and Chinese. The device's ability to reset accumulated data and restore factory settings further simplifies maintenance and management. High Safety & Multiple Protections: Comprehensive safety design supports setting overvoltage, overcurrent, overpower, and overtemperature protecting thresholds. The adjustable low-voltage limit value and discharge time limit value add additional safety, ensuring the device operates within safer boundaries. Efficient Cooling & External Temperature Measurement: An intelligent fan cooling system automatically activates when the internal temperature reaches 40℃ or the current exceeds 3A, ensuring stable operation even under heavy loads. The ability to connect an NTC temperature sensor to measure and display temperatures from 0 to 100°C adds to its functionality and versatility.
