World’s smallest photocouplers optimized for industrial uses
Renesas Electronics Corporation announced five new 8.2mm creepage photocouplers that are the world’s smallest isolation devices for industrial automation equipment and solar inverters. With a package width of 2.5mm, the RV1S92xxA and RV1S22xxA photocouplers reduce PCB mounting area by 35 percent compared to competitive couplers. They help designers shrink equipment size, increase robot axes, and […]
Resolver-based step motor controllers handle heavy loads without step-out
Renesas Electronics Corporation and MinebeaMitsumi Inc. announced the joint development of resolver-based (angle sensor) stepping motor and motor control solutions optimized for use in robots, office automation (OA) equipment, and medical/nursing care equipment. These applications require motors with higher precision motor control, miniaturized form factors, and improved resistance to environmental influences. Working in collaboration, Renesas […]
4U, 30-kW rack-mount programmable dc load returns 95% of power to grid
The EA-ELR 10000 30 KW Programmable Electronic Load is engineered with advanced SiC power conversion devices and boasts the industry’s best power density—requiring as little as half the rack space for the same power output as competing programmable loads. This latest generation ELR combines its high-efficiency programmable dc load with an equally efficient inverter (regenerative) […]
