Product Highlights

From AC line in, to highly regulated DC
out, Vicor offers the total design solution
through a complete family of off-line front
end and DC-DC modular power components.

Vicor’s family of off-line front ends
interface VI-260 and VI-J60 series
DC-DC converters, and MegaMods, 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 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.

Notes:

1. If input power is applied with the DC output BUS shorted, the active inrush circuitry will usually prevent
Fuse 1 from blowing. Remove power, clear shorts, wait a few minutes and reapply input power.

2. If unit is strapped for 115V operation and 230V is applied, the internal overvoltage crowbar will clear

Fuse 1. Replace fuse, strap correctly and reapply power.

3. To control EMI/RFI most effectively, the return path to earth ground from either the front end or
modules should be made via a good RF ground. User must assure proper grounding for safe operation.

Thermal Considerations

Free Convection Derating

• 250W: Derate output power linearly
at 7.2W/˚C over 50˚C.

• 500W: Derate output power linearly
at 14.3W/˚C over 50˚C.

• 750W: Derate output power linearly
at 18.8W/˚C over 45˚C.

Forced Convection:

The curves below represent worst case data for chassis
mounted (enclosed) front ends, i.e., low line, full load.
System conditions such as higher line voltage, lighter
load or PC mount versions of the front ends will
increase reliability if the data here is used as the
nominal design criteria.

The sigmoid shape of the curves at low air flows is due
to the chassis mount cover restricting the airflow to the
inboard components until an airflow of approximately
200 LFM is achieved. Thereafter, the velocity of air
rushing over the cover causes air to be pulled in
through the side perforations, causing a rapid
improvement of cooling of internal components.
