Electrical Input Data

Heatsink (H)

The PST14 is built as standard with a aluminum baseplate as described

in the mechanical data. The converter can be delivered with a 15mm

heatsink. See page 15.

Ruggedized (M)

The PST14 can be ruggedized to meet MIL-STD810E, MIL-STD461E

CE102, on Mini & Maxi only.

M op�on with 12 & 24Vin will comply with MIL STD 1275A.

Input parallel bus bar with capacitor footprints

The input bus bar simplifies the assembly of 2 or 3 PST14. It includes

input extra capacitor footprints for applica�on with long lenght from

the source to the PST14.

Op�ons Descrip�on

Input

Accessories

-40°C opera�on (T)

The thermal grade of the Vicor the DC/DC converters used and other

components are changed to comply with low ambient temperature.

Conformal coa�ng (V)

During manufacturing process, when V op�on is specified, components

and pcb are covered with an acrylic coa�ng to address high level of

ambiant humidity applica�on.

Output parallel bus bar

Available for 2up & 3up versions, it connects together the differents

posi�ve outputs as well as nega�ve output.

Output serial bus bar

From 1up to 4up, this accessory puts in parallel the outputs with the

addi�on of an oring diode mounted on an aluminium bar.

Output N+1 bus bar including diode

These 50mm cables allow unit to current share in parallel and allow the

user to inhibit all units at the same �me.

Inhibi�on and parallel cable

Input Fuse

A fuse mounted inside the converter protects against damages in case

of a failure. The fuse is not user-accessible.

Input Transient Protec�on

A VDR (Voltage Dependent Resistor) and a common mode input filter

form an effec�ve protec�on against input transients in severe environ-

ments like railways.

When M op�on is defined for PST14A&B, the unit is incorpora�ng an

ac�ve protec�on against high energy transient MIL STD 1275, DO160.

See page 16 for details.

Accessories are compa�ble with PST14A, B, C format

It connects the nega�ve of the first unit with the posi�ve of the second

to create high voltage configura�on.

Input Reverse Polarity

A diode placed internally across the input will cause the fuse to blow in

case of a reverse polarity of input voltage.
