Product Description:
Product Advantages
● The core utilizes a 24-bit high-precision AD converter with a sampling frequency
of up to 8000 times per second, and synchronously samples voltage and current. This technology ensures accurate power control and high-precision electrical parameter measurement (voltage, current, and power accuracy are all better than 0.5%) even under rapidly changing load conditions, providing a reliable data foundation for R&D and quality inspection.
● It features three programmable operating modes: constant power (CP), constant current (CC), and constant resistance (CR). Users can flexibly set load parameters according to their testing needs to accurately simulate various real or extreme load conditions, meeting diverse testing scenarios from steady state to dynamic.
● Employing new, highly reliable power-efficient components, it achieves a load capacity of up to 3000W within a compact chassis, demonstrating outstanding power density. A forced-air cooling system with intelligent temperature control ensures stability and extends component lifespan during prolonged full-load operation.
● It supports manual control from the front panel and remote programmable control from the back end via RS-232/485/LAN/USB. It can be easily integrated into an automated test system (ATS) to achieve unattended sequential testing, data recording and analysis, greatly improving testing efficiency and consistency.
● It features built-in multiple hardware protection circuits for overvoltage, overpower, and overtemperature, and includes emergency unloading and short-circuit simulation functions. It can automatically protect against test anomalies, ensuring both the device under test and the load itself, guaranteeing reliable operation.
Application areas
● Inverter and UPS testing: Used to test the load capacity, output stability, conversion efficiency, and dynamic response performance of photovoltaic inverters, energy storage converters, and uninterruptible power supplies (UPS).
● Battery and charging equipment testing: Simulate real loads to perform charge and discharge capacity tests and aging tests on battery packs, or to test the output characteristics and load stability of chargers and on-board chargers (OBCs).
● AC power supply and generator testing: As a standard load, it is used to verify key indicators such as output power, voltage regulation rate, and load effect of AC regulated power supplies, frequency converters, and diesel generator sets.
● Power electronic components and modules: Used for testing the contact load capacity, lifespan, and temperature rise of components such as relays, contactors, and smart switches.
● Home appliances and lighting products: We can test and verify parameters such as power, current, and power factor of home appliances such as air conditioners, washing machines, and LED drivers.
● Scientific research, teaching, and certification testing: Suitable for universities, research institutes, and third-party testing laboratories, providing accurate load conditions for product development and standard compliance verification (such as load testing in CE and UL certification).
