2 / 11 page Input Fuse PST22 Rev. 01 Page 2 of 11 www.powersystemtechnology.com A fuse mounted inside the converter protects against damages in case of a failure. The fuse is not user-accessible.Reverse polarity at the input will cause the fuse to blow . Model Fuse type Ra�ng Reference 24V Litllefuse 15A 251015HE 48V Bussman 15A BK1/MCRW15A 72V Busmann 15 A BK1/MCRW15A 110V Li�lefuse 10A 251010HAT1L Input Transient Protec�on / Electromagne�c Compa�bility (EMC) A VDR (Voltage Dependent Resistor) and a common mode input filter form an effec�ve protec�on against input transients in severe environ- ment like railways with EN50155.

In applica�ons where the com- plete rack is covered by a single panel, the converter can be delivered without front panel. N+1 Redundancy (R) The PST22 is equipped with an internal ac�ve redundant MOSFET circuit providing very high reliability opera�on (described page 4) when R op�on. Very low profil 4TE (S) With S op�on, the height will be reduced to 20,32mm for the front panel, making very suitable for low profil applica�on. The heatsink being significantly reduced , thermal dissipa�on decrease and power -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 ambiant 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.
