Feature:1. 【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.2. 【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.3. 【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.4. 【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.5. 【Efficient Cooling & External Temperature Measurement】: An intelligent fan cooling system automatically activates when the internal temperature reaches 40°C 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.Specification:Name: Electronic Load Material: metalWorking voltage: 12VDCLoad voltage (U): 0-150VDCLoad current (I): 0-20ALoad power (P): 0-150W (maximum load capacity of 60W above 120 V)P=U × I ≤ 150WWiring method: A+V+V - A - four wire system, downward compatible with two wire systemUpper limit of electricity metering: 99999.9WhCapacity measurement upper limit: 99999.9AhAccumulated timing ranges: ddd: hh: mm: ss (day: hour: minute: second)Working mode: Three modesCC - Constant Current ModeCP - Constant Power ModeCR - Constant Resistance ModeOvervoltage protections: SupportOvercurrent protections: SupportOverpower protections: SupportOver temperature protections: When the internal temperature exceeds 75 ℃, over temperature protecting is triggeredVoltage limited discharge: also known as low-voltage protecting, supports, defaults to no voltage limited discharge, and can be set according to needsLimited time discharge: supports maximum 99 hours and 59 minutes of limited time dischargeCooling method: The programmable fan automatically runs when the internal temperature is ≥ 40 ℃ or the current is>3AExternal temperature measurement: Connect the NTC 3950 10K 1% temperature sensor to measure and display the temperature between 0 and 100 ℃Chinese English interface switching: supportAccumulated data reset: supportVoltage and current no-load zeroing: supportVoltage open calibration: supportCurrent open calibration: supportScreen brightness adjustment: supportScreen sleep and standby settings: supportRestore factory settings: supportItem size: 198 * 103 * 85mm / 7.80 * 4.06 * 3.35inItem weight: 933g / 2.06lbPackage size: 216 * 110 * 145mm / 8.50 * 4.33 * 5.71inPackage weight: 1010g / 2.23lbPackage List:Packing List:1 * Electronic Load1 * Temperature Test Wire1 * Adapter
