Control Resources’ new SmartFan Fusion-4 digital fan speed control and alarm board provides a reliable, off-the-shelf control solution for electronic and telecom cooling systems. Fusion-4 can control fan speed based on temperature, single or dual I2C interface or analog control signal (PWM, 5.0 VDC). In addition, Fusion-4 offers ATCA compliance for managed or intelligent FRU cooling systems. In order to fully meet the telecommunication industry’s first open standard for carrier-grade systems, Fusion-4 will communicate with shelf management modules via dual IPMBs as specified by AdvancedTCA PICMG 3.0. The control provides FRU information, individual fan status and temperature readings. Fusion-4 accepts dual power feeds in the range from 36 to 75 VDC and regulates fan speed using a buck regulator control circuit. The board monitors tach pulses from the fans to provide fan status. Fusion-4 can control up to 4 fans and has a current rating of 3 Amps at 55ºC or less ($69.00 ea/200 – available now). Configuration of the Fusion is settable via I2C interface or options can be set at the factory to your specifications. Special and custom configurations are available. Benefits of using SmartFan include acoustical noise reduction, energy savings, greater product reliability, increased fan life and improved safety. |

Control Resources’ LabPower DS1502F is a dual adjustable benchtop power supply designed for powering small digital and analog circuits. Its compact 4.9”H X 6.2”W X 3.3”D size takes very little valuable bench space and makes this benchtop DC power supply very portable. The included digital voltage meters allow easy setting of the supply and reduce the need for external meters. Both 15 volt power supplies are independent allowing +/- configurations as well as dual supply logic circuits.
The DS1502F supply operates from a 115 or 230 VAC power source. The two 0 to 15 VDC outputs are capable of supplying 0 to 12 VDC @ 1000 mA typical and >12 to 15 VDC @ 300 mA typical. The outputs are fully protected from short circuit faults. The output automatically recovers when the short is removed. The active current limiting will fold back the output voltage to prevent arcing and damage to external circuits when a short is applied.
This dual variable benchtop power supply is ideal for test benches, laboratories, universities and repair facilities. The supply weighs 2.4 pounds and comes with a power cord.
($149.00 ea. – available now). |
