NX-1000XY DC High Current Standard Source
The NX-1000BZS DC High Current Standard Source is a flagship product developed through our company's strategic investment in top-tier scientific talent.
The NX-1000XY DC High Current Standard Source is a next-generation high-efficiency programmable DC high current standard source, designed and manufactured in 2026 by our company with concentrated investment in *scientific and technological talent.
This high-current source is specifically designed for calibration of DC high-current clamp meters, shunt devices, DC sensors, and high-current DC standard meters. It can also be used for aging tests of high-current cables and other high-current equipment, with a single module output current of 1000A.
The NX-1000XY adopts a modular design philosophy, featuring a 10.4-inch capacitive touchscreen main control unit with 1024*768 resolution. Its specifications include an Intel i5 fourth-generation processor, 8GB RAM, and a 128GB solid-state drive, running Windows 10 64-bit. By integrating advanced technologies such as resonant soft-switching, synchronous rectification, and servo power amplifier technology, the system significantly reduces internal component power consumption, enhances overall output efficiency, and minimizes device size and weight. Each module operates with independent current output and can be freely connected in parallel, equipped with comprehensive overload and open-circuit protection functions. Multiple units can be combined in parallel to deliver output currents ranging from 1000A to 10KA.
This device is characterized by advanced technology, reliable performance, comprehensive functionality, and user-friendly operation. All functional parameters comply with relevant regulatory requirements, representing another innovative contribution from Qingdao Donglai Electrical Equipment Co., Ltd. to its end-users.
