NEWS 5 Power Electronics Europe Issue 4 2025 Power Electronics Europe shield is a critical value-add for device designers striving to ensure stable, error-free signal performance in space-constrained device designs. Molex says its long-standing collaboration with product developers from major device and gaming manufacturers supports continued enhancements, including the development of the new EMI shielding. Together, Molex and its customer engineering teams addressed the most significant requirements related to signal interference and incremental power requirements, specifically how best to achieve 80 times the signal connections and four times the power delivery compared to a single-pin connector. The new Quad-Row Shield provides power input and output aligned to a delivery model featuring up to 80 pins within a single board-to-board connector. In addition, S-parameter input specifications may be assigned to a preferred pin layout in an 80-pin signal design. The highly innovative Quad-Row Shield significantly reduces electromagnetic interference and meets stringent EMI/EMC standards to lower regulatory testing burdens and speed product approvals. The shielding feature also enables error-free communication while seamlessly supporting operations and maintenance requirements to boost overall system uptime. https://www.molex.com/en-us/home Danfoss Power Solutions has announced the launch of CAN 2 Current (C2C), a compact solenoid-mounted microcontroller designed to work with Danfoss cartridge valves, hydraulic integrated circuits (HICs), hybrid PVG/HIC valves, and open-circuit pumps. C2C connects the valve, HIC, or pump to the controller area network (CAN) bus, enabling accurate and efficient component actuation as well as simple diagnostics. The company says C2C is a high-performance device delivering repeatable and consistent control. The device communicates using CAN bus protocols to provide closed-loop current control on one or two outputs. C2C can be used with on/off and proportional solenoids and is available as either a single- or dual-channel device. The singlechannel device commands one coil while the dualchannel device can command two coils sequentially. It is compliant with ISOBUS and SAE J1939 communication protocols. C2C can maximise energy efficiency through peak-and-hold control technology. This feature reduces current in the hold phase to only the power required to maintain the solenoid’s position, thus holding the function. Using retention current on extended-hold functions, such as clamping, reduces energy consumption by up to 70%. This minimises cooling needs and may reduce the battery capacity required in some types of batteryelectric machinery. The controller’s compact, robust design maximises space efficiency as well as durability. C2C features resin-potted construction that offers protection from dust and dirt, as well as shock and vibration resistance. With its IP67 ingress Danfoss Power Solutions launches CAN 2 Current, a solenoidmounted microcontroller for accurate, efficient component actuation protection rating, C2C is built to last in harsh offhighway environments. By connecting the valve or pump to the CAN bus, C2C simplifies diagnostics. The CAN bus enables real-time communication between the C2C and the machine controller, enabling status messages to be shared with the operator via cabin display. This eliminates the need for manual troubleshooting to identify solenoid issues. “With CAN 2 Current now part of our portfolio of closed-loop current control actuators, Danfoss can deliver a truly fantastic, complete subsystem with all the benefits of CAN bus. Our full portfolio of solutions addresses every requirement, delivering functionality perfectly matched to the machine,” said Michael Hartmann Andresen, Global Product Portfolio Manager, Actuators, Danfoss Power Solutions. “We aim to develop the strongest actuator platform on the market. We will continue to build out our closed-loop CAN actuator portfolio while not forgetting the need for durable, reliable open- and closed-loop analogue actuators.” C2C offers quick and simple setup. The full Danfoss Power Solutions actuator portfolio features a standardised approach for setup and control, which is applicable across C2C and PVE configurations for various valve solutions. The actuators are configured within the PLUS+1 Service Tool, offering a familiar, easy-to-use setup platform. The C2C device’s configurable parameters include communication time guarding, dither, minimum and maximum current, and hold current. https://www.danfoss.com/en-gb/
