PB315 Series
500 WATTS ROLLING STOCK DC/DC CONVERTER
FEATURES
• 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.
