Conduction-Cooled 1000 Watt Power Supplies Feature I2C Bus Communications
San Diego, CA – January 2012– TDK-Lambda Americas, a group company of the TDK Corporation, has launched the new CPFE1000F
series of baseplate/conduction-cooled power supplies capable of providing up to 1000-watts without fans or forced-air cooling, thereby
providing audible-noise-free operation. With a baseplate and ambient operating temperature range of from -40 up to +85°C this new series
of AC-DC power supplies will be of special interest to designers who need high-power but cannot use fans, or where the power supply is mounted
in an enclosure.
These single output power supplies operate
with a wide universal input range of from 90 to 265VAC with PFC and are
available with DC outputs of 12V, 28V (adjustable to 24V) or 48VDC. Due to its
wide output adjustment range of ± 20%, the output voltage can be set to match a
variety of customer-specific applications. The outputs of these units can be connected in series or parallel for higher power applications.
The CPFE1000F series was designed for harsh indoor or outdoor environments and are ideal for such applications as LED signage, RF broadcast,
COTS-military, noise-sensitive Audio/Video equipment, food processing and other industrial/commercial applications. The power supply's baseplate
is designed to easily attach to metal enclosures or other heat-sinking surfaces, thus eliminating the need for fans or forced-air-cooling.
To guard against moisture, dust and other contaminants, the internal PCB assembly has a protective coating.
A distinguishing feature of the CPFE1000F series is its internal I2C bus interface which can send operational parameters of the power
supply to remote locations. These parameters include: output voltage, output current, baseplate temperature, serial number, model number and date-code.
In addition, the I2C interface provides a means to turn the power supply On or Off from a remote site and receive DC Good and over-temperature
signals. In addition to the I2C bus, traditional signals/controls are provided including an Output Good signal, Re-mote On/Off control,
Active Current-Share, and an Auxiliary-Output of 12V/20mA.
All models in the CPFE1000F series include TDK-Lambda's two-year warranty and meet EN55022/EN55011 Class B and MIL-STD 461/462D CE102 EMC
specifications, thereby simplifying system designs. In addition, these supplies meet shock and vibration specs per MIL-STD-810E under operating
and non-operating conditions. "Power supplies that meet the tough EMI specs per MIL-STD 461/462D, plus shock and vibration specs per MIL-STD-810E,
are often custom-designs and can cost up to 10 times the price of the CPFE1000F," says David Norton, V.P. of Marketing for TDK-Lambda Americas.
"The CPFE1000F provides a very reasonably priced COTS power solution. In addition, these units feature a lightning
surge capability of up to 6kV and an input-to-output isolation of 4.25kVdc, ensuring the supplies will be both rugged and reliable," says Norton.
The new 1000-watt baseplate/conduction-cooled CPFE1000F models are available now and priced at $825.00 each in 50 piece quantities. More information
