This third-generation series accepts a wide 85 to 305 Vac input range, providing the ability to operate on a 277 Vac nominal input to power industrial, lighting, and building automation equipment. The module’s metal baseplate allows operation where convection or forced air cooling is not feasible, with the ability to be mounted in a sealed outdoor enclosure or where liquid-cooling is preferred. The five-sided case also provides easier thermal management and lower radiated EMI.
The PFE1500FB features a PMBus interface with read/write capability, enabling remote monitoring and programming. This includes output voltage, overvoltage, overcurrent, and undervoltage adjustment. Modules can be connected in parallel for higher output current using the droop mode current share, which can also be programmed using the PMBus. Other signals and functions include remote on/off, a power good signal and a 9.5 - 14 V, 200 mA auxiliary voltage. The output voltage adjustment range is 38.4 - 57.6 with typical efficiencies of 92 % at 230 Vac input. The no-load power consumption is 2 W with the output voltage enable toggled to “off”.
Overall dimensions for the power module are 157.2 x 89.9 x 15.2 mm (L x W x H) and the weight 540 g.
Safety certifications include IEC/UL/CSA/EN62368-1 and carry the CE and UKCA marking for the Low Voltage, EMC and RoHS Directives. The units also comply with EN55032-A with external filtering, meeting the IEC 61000-4 immunity standards. The power supply has 3000 Vac input to output, 2500 Vac input to ground, and 1500 Vdc output to ground isolation. The series is available with a three-year warranty.
