Description
The 150W 2.4-Inch DC Electronic Load Battery Tester is a versatile, high-precision power diagnostic tool engineered to evaluate the capacity, discharge performance, and power delivery of lithium-ion, LiFePO4, and various other DC power sources. Featuring a bright 2.4-inch display screen, this instrument monitors vital electrical metrics in real time, including voltage, current, power, impedance, cumulative run time, and total watt-hours (Wh).
Equipped with an automatic temperature-controlled cooling fan that engages when internal temperatures exceed 40°C, the unit ensures stable, continuous performance under heavy loads up to 150W. It features customizable over-limit warnings with both visual screen prompts and audible buzzer alerts, adjustable screen standby timers, and an automatic run-time accumulator that starts recording as soon as current passes 0.05A.
Note: Product design or firmware interface may vary slightly based on manufacturing batches. Package includes 1 electronic load tester unit as specified.
Key Features
- 150W Electronic Load Capacity: Robust heat dissipation and power handling for heavy-duty DC load and discharge testing.
- Vibrant 2.4-Inch Display Screen: Clear visual layout presents all critical electrical metrics, test parameters, and run times at a glance.
- Smart Thermal Fan Control: Automatically activates cooling fan operation when internal temperatures surpass 40°C to prevent overheating.
- Dual Over-Limit Alarm System: Configurable safety alerts featuring both visual interface warnings and an active buzzer alarm.
- Run-Time Accumulation: Automatically initiates time logging when current exceeds 0.05A for accurate discharge duration tracking.
- Wide Testing Parameters: Measures working voltages from 5V to 150V DC, resistance up to 9999.999 ohms, and capacity up to 999.999Wh.
Benefits
- Accurate Battery Capacity Grading: Measure true milliamp-hour (mAh) and watt-hour (Wh) delivery to verify battery health and authentic capacity specs.
- Safe High-Load Operation: Smart thermal management and over-limit alarms protect both the tester and your power sources during extended discharge cycles.
- Flexible Standby Controls: Configure screen standby timing from continuous “always on” to custom intervals between 0 and 99 seconds.
- Comprehensive Telemetry: Track voltage, current, power, impedance, and elapsed time simultaneously on a single, easy-to-read dashboard screen.
Applications
- Lithium Battery Pack Testing: Capacity verification and discharge aging tests for Li-Ion and LiFePO4 battery assemblies.
- USB Charger & Power Bank Evaluation: Verify max current thresholds, voltage sag, and output stability for portable power banks and wall adapters.
- DC Power Supply Bench Testing: Load testing switching power supplies, LED drivers, and custom power circuits under sustained operational demands.
- Electronics R&D Workshops: Performance analysis for DIY electronics projects, solar power setups, and energy storage prototypes.
