Controlling Device for Rotational Speed of Fans with PWM Control
Sanyo Denki has released the “San Ace PWM Controller”, a device for controlling the rotational speed of fans that have PWM control function. The controller’s main features include: reduced system power consumption and fan noise, the ability to be common-powered by the fan power supply of rated voltage 12, 24, and 48 VDC (with no separate supply required), and having a maximum … [Read more...]
Calculation Corner: Spreadsheet-based Matrix Analysis – Extension to Transient Analysis
by Ross Wilcoxon, Ph.D., Associate Technical Editor Over the years, a number of articles [1-3] published in ElectronicsCooling have described the use of thermal resistance networks to analyze electronic systems. The analysis of a thermal resistance network begins by defining discrete nodes that are connected with resistors, with the magnitude of a flow between nodes defined … [Read more...]
Surface Temperatures of Electronics Products: Appliances vs. Wearables
by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling Online Prior to designing the requisite thermal management solution, engineers routinely calculate the junction temperatures of active and passive components using various methods at their disposal –finite difference grids, lumped parameter models, finite element methods, etc. The junction … [Read more...]
