JARO's new micro-sized "Whisper" (TM) Blower measures in at an impressively tiny 20 X 20 X 6 mm (6000 RPM ± 20%), and offers a virtually-soundless operation. Thanks to a unique Aerospace-Fluid Bearing system, this new micro-sized DC blower provides exceptionally high static pressure, while offering a very low operating volume (16 dB). The new blower offers a super-low … [Read more...]
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...]
Book Review of Electronics Cooling (2016)
by MP Divakar, PhD, Stack Design Automation Technical Editor, Electronics Cooling Online Electronics cooling engineers and designers are used to one constant in their professional lives: change. Most of it (as far as problem solving is concerned) is change for the worse… and is challenging! The heat flux keeps increasing, the geometries keep shrinking, the available solution … [Read more...]
New Power Supply Units Introduced
SilverStone’s Strider Platinum series has two new additions, the ST1000-PT and ST1200-PT units. Along with being the world's smallest 80 PLUS Platinum, fully-modular ATX power supplies, the ST1000-PT and ST1200-PT units are two of six, all with capacities ranging from 550W to 1.2 kW. Both new high-end Strider Platinum units have restricted dimensions, with only 18cm depth, and … [Read more...]
New Internal PWM Signal Control Fans
Delta’s new PWM (pulse-width modulation) regulates the voltage signal between fully on and fully off, controlling the speed of a fan. The PWM function is commonly used in OEM cases. Delta also provides standard PWM through distribution channels. Delta's internal PWM signal control fans deliver a variety of advantages over external PWM controlled devices, such as wide PWM … [Read more...]
