Product Features
Multi-path packet load distribution with flexible handling
It features 30 built-in 20Ω/600W chip resistors arranged in 10 sets of aviation connector outputs, supporting single or multi-channel load configuration with a total power output of 18 kW, ideal for multi-channel synchronous testing.
High-precision stable load with minimal testing error
The sheet resistor exhibits a precision of ±3%, a power factor of 0.99, excellent resistance consistency, stable performance under load conditions, and ensures accurate test data for power supply and battery products.
Powerful wind cooling for continuous operation around the clock
The forward unit features a forced air cooling system paired with a 15050 fan for efficient heat dissipation; it supports 24/7 uninterrupted operation and resists overheating under prolonged full load.
Standard industrial cabinet, suitable for indoor use
Standard cabinet with portable design, protection rating IP20; compatible with AC220V universal power supply and operates stably across a wide temperature range of-10°C to 50°C.
Application Scenarios
Aging Testing of Power Supply Products
Full-power load aging tests for switching power supplies, chargers, adapters, and vehicle-mounted power supplies under simulated rated operating conditions.
Battery/Energy Storage Discharge Testing
Performance verification of lithium battery packs, energy storage power supplies, temperature rise, and voltage drop.
Performance Verification of DC Power Modules
Steady-state load testing of charging station modules, UPS units, and micro-inverters, simulating a scenario where multiple devices draw power in parallel.
Electrical Teaching Laboratory Practical Training
For electrical engineering majors in universities, experiments related to circuits and power supply provide standard constant resistance loads.
Three Common Questions
Q1: What are the total power and single-channel parameters of the device?
A: Single channel: 20 Ω/600 W; total of 30 channels, with a total power of 18 kW; each aviation connector contains 3 resistance channels.
Q2: Can it operate continuously over the long term? What is the warranty period?
A: Supports 24/7 continuous online operation with a full-year warranty.
Q3: What are the limitations of the device's operating environment?
A: Suitable only for indoor, dry, and well-ventilated environments; operating temperature range: -10°C to 50°C; protection rating: IP20; not recommended for outdoor use in rainy conditions.
Q4: What is the cooling method, and does it require an additional fan?
A: Equipped with a built-in 15050 fan for forced air cooling, featuring front and rear airflow channels that eliminate the need for additional cooling components—ensuring sufficient ventilation space throughout the cabinet.
