Multi-channel constant current generator that can be variably set to arbitrary currents at high speed from a PC.
IMG25A 10CH Programmable Constant Current Generator
Custom production of the number of channels, current values, and voltage values is possible. Constant current for 10 channels can be set arbitrarily from a PC (USB) with an update speed of less than 500 μsec.
It outputs a constant current to loads controlled by current, such as optical semiconductors. The current values for each of the 10 channels can be set independently, and updates can be made at speeds below 500μsec using a USB interface. It is a portable device powered by an AC adapter. In addition to setting the current, it is also possible to read the load voltage. Current setting and voltage reading are performed via communication through separate USB connectors. Customization for the number of channels, current values, and voltage values is possible. We have a proven track record of up to 1024 channels. Please feel free to consult with us.

Company information
Our company is a proposal-based prototype development specialist manufacturer that develops custom electronic devices and the systems that connect them. We realize "measuring, thinking, and connecting" with unique ideas to meet our customers' needs. Please feel free to consult us about anything, whether it's "I want to make this," "I'm having trouble," or "I want to improve this." To materialize our customers' new ideas, we provide proposals and support through manufacturing. By using custom products that align with your company's values instead of fitting your values to off-the-shelf products, we lead you to high-value work. This enhances your company's value and increases productivity. It is our pleasure to respect diversity and provide and support such electronic devices. Sensors capture various phenomena, low-noise analog circuits process the reality as perceived by humans, digital signal processing performs analysis and feature extraction, and interfaces communicate the necessary results to people. The fields where we can apply our expertise in hardware/software signal processing are broad, and we continue to challenge ourselves in custom manufacturing and real-time processing based on our extensive development achievements and proprietary technologies.
