Features two built-in 15 kW loads; supports parallel operation with a full load of 30 kW at AC 120 V input; supports external wiring switching for series connection under split-phase 240 V conditions, compatible with North American 120/240 V single-phase power systems.
Reliable forced air cooling system for heat dissipation.
Configure 6 units of 15050 fans (AC220V). The air ducts provide forced air cooling from right to left, ensuring controlled temperature rise under prolonged full-load conditions. Suitable for a wide operating temperature range of-10°C to 50°C.
Pure resistive load
A pure resistive load with no harmonic interference, suitable for aging tests and load verification of power supply products.
Application Scenarios
Aging Test for Specified Power Products in North America
The AC120V inverter, switching power supply, adapter, and uninterruptible power supply (UPS) come from the factory with load aging tests performed under full load and step-load conditions.
Inspection of small power generation units and portable generators
Output capability verification, steady-state load test, and performance sampling inspection for 120V single-phase generators
Energy storage converters and testing of small-scale energy storage power supplies
120V Output Energy Storage Module Load Capacity and Continuous Discharge Simulation Test
Laboratory Development and Validation
Power supply development condition simulation, output voltage drop, temperature rise, and full-load reliability testing
Common Questions
Q1: What is the maximum power this unit can handle?
A: It operates on 120 V AC with two parallel circuits, delivering a rated total power of 30 kW. When connected in series to a 240 V split-phase supply, it maintains the same total power output of 30 kW, requiring manual switching – the cabinet cannot perform automatic switching.
Q2: Can only one of the 15 kW circuits be enabled separately?
A: Yes. The equipment has two independent terminal groups (L1, N1 and L2, N2) that can operate with either circuit individually or both simultaneously.
Q3: Is the fan powered by the test power supply (AC 120 V)?
A: No. The fan has an independent auxiliary power supply (AC 220 V, 50 Hz) and must be connected to a separate 220 V mains source; it cannot use the tested 120 V power supply.
Q4: Does an ambient temperature upper limit of 50°C indicate that the device can operate under full load at 50°C for extended periods?
A: The permissible operating environment range is-10°C to 50°C; in high-temperature conditions (>40°C), it is recommended to reduce power consumption appropriately to extend the service life of the resistor and ensure adequate ventilation.
