504W AC-DC conduction cooled power module offers leading edge size and PMBus™ communications
TDK Corporation (TSE
6762) announces the introduction of the TDK-Lambda brand PFH500F?28 high
efficiency AC-DC power supplies. Rated at 504W, the baseplate conduction-cooled
module is packaged in a compact 101.6mm x 61mm footprint. Using industry
standard PMBus™ commands, the output voltage and fault management levels can be
adjusted (read/write) and product status read back. The PFH500F series has been
designed for outstanding performance in COTS (Commercial-Off-The-Shelf), LED
signage, communications, broadcast, test and measurement equipment.
The PFH500F-28 has an operating efficiency of up to 92%, enabled through the use of the latest technology. This includes GaN semiconductors, bridgeless power factor correction with synchronous rectification and digital control. A digital isolator replaces the traditional optocoupler for long term stability and reliability.
Operating from a wide range 85 to 265Vac input, the PFH500F-28 will deliver 18A at 28V with an adjustment capability of 22.4 – 33.6V via the trim pin or the PMBus™. Other output voltages will be available later in 2018. The module has a baseplate temperature range of -40°C to +100°C and measures 101.6 x 61 x 13.5mm (L x W x H).
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, output trim and PMBus™ communication. 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.
Input to output isolation is 3,000Vac, input to case 2,500Vac and 1,500Vdc output to case. Safety certification is to IEC/EN/UL 60950-1 standards with CE marking for the Low Voltage and RoHS2 Directives.
