The power modules can be programmed (read\/write) or remotely monitored (read) through the industry-standard PMBus interface. The PFH500F series delivers outstanding performance in COTS (Commercial-Off-The-Shelf), LED signage, power amplifiers, and test and measurement equipment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <strong><a href=\"http:\/\/www.emea.lambda.tdk.com\/uk\/products\/pfh500f\" target=\"_blank\" rel=\"noreferrer noopener\">PFH500F-12 and PFH500F-48<\/a><\/strong> utilise the latest technologies, including GaN semiconductors, bridgeless power factor correction and digital control to achieve efficiencies of up to 92%. Digital isolators replace traditional optocouplers for long-term stability and reliability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Operating from a wide range 85 to 265Vac input, the PFH500F-12 will deliver 42A at 12V with an adjustment capability of 9.6 \u2013 14.4V using the trim pin or the PMBus\u2122 interface. The PFH500F-48 delivers 10.5A at 48V and can be adjusted from 38.4 &#8211; 52.8V. The modules have a baseplate temperature range of -40\u00b0C to +100\u00b0C and measure 101.6 x 61.0 x 13.5mm (L x W x H).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Product features and options include droop mode current share, a 12V auxiliary standby output, remote on\/off, remote sense, an open collector power good signal and output trim. The PMBus can be used to program the output voltage, activate the remote on\/off, change the under\/over-voltage, over-current and over-temperature set points, plus read-back input and output current, input voltage and internal temperature.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The input to output isolation is 3,000Vac, input to case 2,500Vac and 1,500Vdc output to case. Safety certification is to the IEC\/UL\/CSA\/EN 62368-1 standards with CE and UKCA marking for the Low Voltage and RoHS Directives. For ease of testing, fully populated evaluation boards are available.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>TDK Corporation announces the introduction of 12V and 48V output models to the TDK-Lambda brand PFH500F series of high-efficiency AC-DC power modules.&nbsp; The series, rated at 504W, can be conduction-cooled to a cold plate for outdoor applications.
