N8336 series ultra high precision multi-channel battery simulator

The N8336 series adopts a standard 19 inch 2U chassis, which can accommodate up to 16CH per unit. The channels are isolated from each other, and one device can test 16 workstations simultaneously, greatly reducing the amount of equipment used by users during testing and improving testing efficiency.

The N8336 series has ultra-high voltage accuracy of up to one in 60000, as well as current resolution of up to 10nA and voltage resolution of up to 10 μ V, in the technology industry. With a voltage accuracy of up to 0.1mV and current measurement of n, it can provide high-precision DC power supply and ultra high precision voltage and current measurement for product testing. It is widely used in the research and development of BMS, CMS, portable consumer electronics (Bluetooth earphones, power tools, etc.) testing and product performance testing.

When multiple strings of battery cells are required, multiple battery simulators can be used in series with multiple channels, and users can also perform remote control and other automatic testing applications through the Ethernet standard interface.

The advantage of low output noise truly presents the ripple free DC characteristics of battery cells. When the load changes dynamically, it can quickly provide stable DC output feedback, while reducing the damage to the test object caused by surge voltage due to load changes. For non static product testing applications, it can provide a stable DC voltage source in a timely manner. The N8336 series battery cell simulator has fast dynamic response speed and simulates battery characteristics more realistically.

The N8336 series battery simulator supports various battery simulation functions and features such as power mode, charging mode, SOC testing, sequence testing, channel readback, real-time curve, CAN settings, etc. One instrument can achieve multiple purposes, streamline testing equipment, and optimize testing processes. And the internal circuit of N8336 is optimized for different chips, which can adapt to various specifications of BMS chip testing.
