Product Description
Product Features
  1. A precisely adjustable multi-level load design with multiple adjustment settings:The power settings support combinations of 1A,2A,5A, and 10A with step accuracy up to 1A, enabling flexible simulation of loads with varying power requirements across various test scenarios up to DC 60V and 3 kW. Resistance accuracy is ±3%, ensuring reliable test data.
  2. Compact standard rack-mounted design:Featuring a 4U standard rack-mounted design with a weight of ≤29 kg, it is compatible with standard cabinets and can be easily moved using a combination of a handheld handle and foot pad, making it suitable for deployment in various environments such as laboratories, server rooms, and production lines.
  3. Reliable and efficient heat dissipation combined with excellent operational performance:Equipped with forced air cooling (2 x 1505 fans, powered by 220 V AC), the unit features a forward-to-rear airflow design to ensure unobstructed air passage. It supports 24/7 continuous operation and comes with a 1-year warranty, meeting stringent stability requirements for prolonged aging tests and full-load operations.
  4. A comprehensive security protection mechanism:It features a triple safety protection system comprising overheat alarm, emergency stop button, and overvoltage protection (supporting up to 1.1 times the rated voltage), effectively preventing damage to equipment and tested power supplies caused by overvoltage, overheating, or accidental operation, ensuring safe testing processes.
  5. Intuitive and user-friendly operation and display:The manual circuit breaker control system features a simple and user-friendly operation. Its digital display interface provides real-time visualization of voltage, current, and power parameters, offering clear visibility of test status. The auxiliary power supply utilizes a standard electrical socket, while the terminal-type load output accommodates various tested devices, ensuring convenient wiring.
  6. Adaptability to various operating conditions:Operating temperature range: 10°C to 50°C; supports indoor IP20 protection rating, ensuring stable performance in dry, well-ventilated industrial and laboratory environments, and meets diverse testing requirements.
Application Scenarios
  1. DC Power Supply/Module Aging and Performance Testing :Conduct aging tests and load capability verification on DC60V specification DC power supplies, communication power modules, and industrial power adapters by simulating actual operating loads to assess voltage stability, current stability, and full-load operational reliability.
  2. Energy Storage and Battery Testing Scenarios:For discharge testing, capacity verification, and performance aging evaluation of DC 60V energy storage devices such as lithium battery packs and lead-acid battery packs, it precisely controls the discharge current to obtain key parameters including battery capacity and internal resistance.
  3. Testing of data center and communication base station equipment:Perform load simulation tests for the DC 60 V power supply systems and backup power supplies in data centers and communication base stations to verify the output stability and emergency switching capability of the power systems under various loads.
  4. Testing and Verification of New Energy Equipment:This test is designed for loads connected to the DC output side of small-scale photovoltaic inverters and wind turbines, verifying the equipment's output characteristics across various power levels and providing a reliable basis for product debugging and factory testing.
  5. Commissioning and Maintenance of Industrial Equipment:Used for load simulation testing of industrial control power supplies and small DC motor drive power supplies, it identifies potential faults under rated or overload conditions to ensure reliable on-site operation of equipment.
Troubleshooting
  • Q1: The device fails to start properly or shows no response when powered on. How should I troubleshoot this? A:
  • ① Check if the auxiliary power supply (AC 220 V, 50 Hz) is functioning properly and ensure the power cable is securely connected;
  • ② Verify that the emergency stop button is pressed; reset it and try again;
  • ③ Confirm that the load circuit breaker is closed to resolve any tripping issues.
  • Q2: If the fan does not operate after the device starts, how should this be addressed? A:
  • ① Check whether the fan's power supply lines are loose or have poor contact; 
  • ② Ensure the air duct is free of foreign objects and that the inlet and outlet vents remain unobstructed;
  • ③ If the fan still does not operate, it may be faulty and should be replaced by contacting the manufacturer to prevent equipment overheating due to inadequate heat dissipation.
  • Q3: If a overheating alarm occurs during testing, what should I do? A:
  • ① Immediately halt the test and verify whether the ambient temperature exceeds 50°C or ventilation is inadequate;
  • ② Confirm that the current load power does not exceed the device's rated capacity of 3 kW to avoid prolonged overload operation;
  • ③ Check whether the fan is operating normally and whether the air ducts are blocked. Once the equipment has cooled to normal temperature, identify the issue and restart testing.
