California Instruments 846CM Control Module

The California Instruments 846CM is a programmable AC power source controller module designed for integration with compatible power amplifier systems. It serves as an interface between an ATE system’s host computer and the power amplifier, enabling both remote and local programming capabilities. The 846CM is designed to work in conjunction with California Instruments’ T Series power amplifiers, which are available in single and multi-phase configurations. This modular approach allows for the creation of power sources that can be scaled to meet specific voltage, current, and output power requirements, with multiple power amplifiers capable of being configured for higher output capabilities.
