Vicor's family of off-line front ends interface any 300 Vin DC-DC converters or configurable products, to 100, 115, 230 or 240 Vac single-phase and 208 Vac three-phase mains.

In addition, front ends provide conducted EMI/RFI filtering to FCC/VDE (Class B singlephase, Class A three-phase), transient surge protection, active inrush limiting, a BUS OK status output (suitable for controlling Vicor DC-DC converter modules via their Gate In pin) and an AC OK status output for system use in the event of loss of the AC line.
