No fans and no noise
03 August 2010
TDK-Lambda’s CPFE500 range of baseplate-cooled power supplies provide 500W without needing fans.
With an extended temperature range of -40°C to +85°C, this range of AC-DC power supplies will benefit engineers that need high power but cannot use fans, or where the unit is sealed in an enclosure.
The power supply is available with protective coating to protect against the ingress of dust, moisture and other contaminants, making the CPFE500 suitable for harsh, dusty or outdoor use, such as broadcast, LED signage, or COTS military applications. Since there is no fan, the CPFE500 series is equally suited to low audible noise applications, such as audio mixing desks and recording studios. All models in the CPFE500 range are delivered with TDK-Lambda's three-year warranty, and meet EN55022/EN55011 Class B and MIL STD 461/462D CE102 EMC specifications.
These single output power supplies are available in 12V, 28V or 48V DC versions. Up to ±20% output voltage adjustment is possible, enabling the CPFE500 to be used in a variety of customer-specific bulk-power applications. Efficiency of up to 88% ensures heat dissipation is minimised. Operating from a universal input of 85 to 265V AC with PFC, the CPFE500 can operate in series or parallel with built in ORing diode and active current share as standard. A power on signal, remote on/off, and remote sense are included.
