VEW 146025501 RED
Two international standards are used to regulate the compliance of electrical and electronic equipment in railway applications:
IEC571, EN50155, (UK) RIA12
RIA 12 (UK) requires overvoltage protection exceeding those of the requirements in the European standards.
The present power supply meets or exceeds all the basic standards.
The device was developed as a pin and functionally compatible redesign for a plug-and-play replacement of the power supply type 146025501 and has fully modular design.
The input modules are designed for an input voltage of nom. 110V DC.
According to EN50155, the necessary input voltage range is 0.7...1.25 x UN = 77...137V.
The under/over voltage range needs to include both 66 V and 154V.
The modules used are designed for 66V to 154V and are also equipped with an active transient protection, which securely eliminates the RIA12-specificed overvoltage (for 20 mS) of the 3.5V-times of the nominal input voltage of up to 385V, as well as peaks of up to 1800V/50µs.
The MTBF is > 250.000h for the module, which meets the life requirements for railway equipment of 24h/d for 30a.
The installation box meets the requirements for railway applications, is extremely robust and can resist a vibration load on three axels with and amplitude of 7.5mm at 5-150Hz and acceleration of 20m/s².
