Product Features
Dual-voltage compatible with strong test versatility Supports AC110V/220V 50/60Hz voltage switching, compatible with both domestic and international AC products; rated at 5 kW with a power factor of 1, designed for real-world electrical conditions, and comes with an integrated AC220V auxiliary power supply without requiring additional power.
High-precision adjustable grading with intuitive readings Multiple power levels can be freely combined with a minimum adjustment step of 100 W. The chip resistor offers an accuracy of ±3%. The screen displays voltage, current, and power in real-time, accurately simulating light load, half-load, and full-load conditions.
stable long-term heat dissipation performance, enabling round-the-clock operation The system features a through-type forced air cooling configuration with high heat dissipation efficiency; supports continuous operation 24/7, operates stably under a wide temperature range of-10°C to 50°C, and comes with a one-year warranty.
Multiple security protections for convenient mobile wiring Equipped with triple protection against overheating, overvoltage, and emergency shutdown, featuring IP20 indoor protection; designed for easy portability with a handheld unit and casters, and offers two output options: high-power terminals and standard power sockets.
Application Scenarios
Aging tests for AC/DC power supplies and inverters The finished products—including adapter switch-mode power supplies, UPS systems, energy storage inverters, and output adapters—have undergone full-load durability aging tests, with dual voltage coverage of 110/220 V for both domestic and international market models during factory inspection.
Calibration of small generators and portable energy storage systems For load performance testing of gasoline/diesel generators and household energy storage systems, evaluating key characteristics such as voltage stabilization, continuous output, and stepwise load startup.
Performance Testing of the On-board OBC (On-Board Charging System) and AC Charging Station Module Simulate the dynamic load during vehicle charging, adjust power in segments to represent different charging phases, and verify the stability and protection functionality of the charging station under prolonged load conditions.
Laboratory research and development: Temperature rise testing of low-voltage components Prototype development evaluation and third-party certification testing; current-carrying temperature rise tests for circuit breakers, terminal blocks, and relays to obtain reliable test data through precise load control.
Common Issues in Various Scenarios
Q1: Export products are available in two voltage specifications (110V and 220V). Do we need to purchase two load cabinets? A: No need – this device supports switching between AC 110V and AC 220V, enabling a single unit to accommodate both domestic and international power adapters and inverters as they age, thereby reducing equipment procurement and storage costs.
Q2: Does direct loading at high speed easily shock the generator, causing overload damage to the unit? A: The device's minimum adjustment level is 100 W, allowing gradual power accumulation to avoid sudden high-power surges and protect both the generator and the energy storage prototype.
Q3: Does the dynamic power variation during charging make it impossible for a fixed load to simulate actual charging conditions? A: Multiple voltage levels can be freely combined and stacked, allowing real-time adjustment of output power to simulate various load conditions such as fast charging, slow charging, and discharge under full charge.
Q4: The temperature rise test requires high load accuracy; conventional loads introduce significant errors, rendering the test data invalid. A: High-precision chip resistors are used with an error margin of only ±3%, ensuring stable output power and minimal deviation in temperature rise test results, fully complying with R&D and third-party certification standards.
