Product Features
1. Multi-voltage compatibility
• Multi-voltage compatibility: Supports three DC voltage levels (DC12V/DC24V/DC48V), enabling a single device to cover various low-voltage DC power supply testing scenarios; Rated power: 5 kW; Pure resistive load; Power factor = 1
2. Tiered adjustable load
Multi-range current stepwise adjustment with clear settings for flexible load combination; resistance accuracy ±1%, stable load output, and precise test data.
3. Powerful cooling system
Bottom-up forced air cooling system featuring two 220VAC, 20060 high-airflow fans; controlled temperature rise even under prolonged heavy-load conditions; supports 7×24-hour continuous online operation.
4. Enhance security measures
Integrates overcurrent, overheating alarm, overvoltage protection, and fan fault alarms; an optional emergency stop function is available; this multi-layered protection prevents damage to both the equipment and the power supply under test.
Application Scenarios
1. Battery Bank Discharge Test
12V/24V/48V lead-acid and lithium-ion battery pack capacity testing, discharge aging test, and backup power supply load-carrying capability verification
2DC power supply and switching power supply aging test
Communication power supplies, industrial DC power supplies, adapters, and vehicle-mounted power supplies – full-load aging and continuous load reliability testing
3.Energy storage system & UPS DC unit testing
Low-voltage energy storage module, DC-DC converter, and uninterruptible power supply (UPS) DC output performance calibration
4.New energy supporting equipment commissioning
Photovoltaic low-voltage controllers, small DC charging station modules, and vehicle electrical equipment R&D and testing
Common Questions & Answers
Q1:Can a 12V,24V, or 48V power supply be used simultaneously?
A:No; the device features a single-loop input – only one voltage level can be selected for connection at any given time; simultaneous connection of multiple voltage levels to the load is prohibited.
Q2:How to check the maximum load current?
A: 48V: Maximum current – 40A; 24V: Maximum current – 20A; 12V: Maximum current – 20A; The "Prohibited Load" position on the table indicates that switching on the circuit breaker is strictly prohibited to prevent resistor burnout due to overload.
Q3:What causes an equipment overheating alarm?
A:① Air intake or exhaust ducts are blocked – clean the dust filter;
② Excessively high ambient temperature or poor ventilation;
③ Prolonged continuous operation at full load;
④ Fan malfunction. In case of overheating, immediately reduce the load or shut down the unit for cooling.
Q4: Can the fan be used even if it isn't turning?
A:No. Once the fan fault alarm is triggered, loading is prohibited; the forced failure of air cooling can rapidly cause resistance overheating and damage – please troubleshoot the fan power supply or replace the fan.
