High-Power Adjusting DC Resistive Load Box

The High-Power DC Resistive Load Regulator is a versatile and high-performance testing device, designed for testing and simulating DC resistive loads. It plays a crucial role, especially in charger桩 testing, the construction and maintenance of electric vehicle charging stations.

Firstly, from a product functionality perspective, this load box features DC ripple measurement capabilities, accurately measuring and displaying a wide dynamic range of AC ripples, which is crucial for evaluating the performance and stability of charging equipment. Additionally, it can real-time display and record voltage, current, power, and energy waveform during the charging process, providing rich data support for analyzing the charging process. Simultaneously, the environmental temperature measurement function can real-time sense the on-site temperature, thus correcting working errors and improving the accuracy of testing. Built-inGPSThe clock module not only provides real-time clock display but also allows for Beijing Time synchronization of the charger, ensuring the accuracy and reliability of test results.

The load box features a wideband AC/DC current comparator technology, offering a smaller thermoelectric potential impact and higher accuracy compared to分流器. Direct measurement of high currents is possible without wiring, automatically completing preset test projects with a single connection, significantly enhancing testing efficiency. Additionally, the absence of switches, relays, and other mechanical contacts in the current circuit ensures high reliability even under overload conditions. The high isolation design effectively separates the current measurement circuit from the voltage circuit and power supply, enhancing equipment safety. The high-definition LCD touch screen and various communication interfaces make operation more convenient and facilitate the establishment of automatic testing systems.

In terms of testing capabilities, this load box is capable of certifying the metering characteristics of charging power, including the working error of non-vehicle charging stations and the display error of the charged amount. Additionally, it can conduct conduction charging interoperability tests, covering multiple test items across various stages such as connection confirmation, charging readiness, and normal charging completion. Moreover, communication protocol consistency tests are also among its key testing contents.
