Designed from the ground up specifically for Rolling Stock.
High temp operation without additional heatsinking. No
additional cold plate necessary.
Protection functions (excluding output overvoltage) auto reset,
unit restarts once fault is removed.
No vent holes, conformal coating of PCB. High degree of
protection against dust / moisture / pollution ingress.
Ruggedised mechanically for shock and vibration. Input
protection against, spikes, bursts and high ripple.
Meets EN50155 operating conditions, EN50121 for EMC / EMI.
