Industrial isolated PFC modules for industrial AC/DC power supplies

Primarily aimed at designers of AC/DC power supplies used in industrial applications, Luso Electronics announces availability of a family of PFC modules, generating an isolated regulated output and completely encased to provide protection from harsh environments. SynQor’s industrial PFC modules accept a wide AC input voltage of 85–264Vrms and deliver isolated, regulated voltages of between 12V–48V with a power output of 325W. With a high overall efficiency of 92%, the devices provide a usable mains to isolated DC output with a minimal number of external components. This approach eliminates the need to utilise another brick after the PFC thereby reducing overall component costs. The family of half-brick modules are the PFICU12HTx27 (12V output voltage), PFICU24HTx14 (24V), PFICU28HTx12 (28V) and PFICU48HTx07 (48V). Regulated and semi-regulated (droop version) modules are available. When used in conjunction with their AC line filter and a hold-up capacitor, the system draws nearly perfect and well-balanced sinusoidal line currents (PF>0.99). SynQor’s industrial PFC modules can operate at full power from -40C to +100C baseplate temperature, and are perfectly suited to harsh environments. Protection features include an input current limit and auto-recovery short-circuit protection along with auto-recovery input under/over-voltage protection and auto-recovery thermal shutdown.
