Off-line Front End

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

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