Input Fuse

An internal fuse protects against damages in case of a failure. The fuse is not

user-accessible.

Input Transient Protection / Electromagnetic Compatibility (EMC)

A VDR (Voltage Dependent Resistor) added with the active input protection

and a common mode input filter form an effective protection against input

transients.

Input Reverse polarity Protection

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

case of a reverse polarity .

Options Description

-55°C operation (T)

The thermal grade of internal Vicor converter and other components are chan-

ged to comply with such low ambiant temperature.

Conformal coating (V)

During manufacturing process , when V option is specified, components and

pcb are covered with an acrylic coating to address high level of ambiant

humidity application.

Heatsink option (H) for convection operation

With the H option , a 15mm heatsink with is added on the baseplate for convec-

tion or air forced operation . The overall height of the converter is then 30mm.
