VEW E44010-A5700 L08C RED
Requirements have been made tougher for electrical and electronic equipment in public transit vehicles in terms of life, reliability, freedom from faults, long-term operations and availability.
This power supply is a redesign of the original Siemens module and meets or exceeds the fundamental standards (EN 60950, Ul60950).
The devices are made to be pin and functionally compatible replacement for the Siemens DC/DC converter E44010-A5700-L08C. It has a modular structure.
The input modules for the galvanic separation of the input/output voltage are designed for nominal 24 DC current. Separation voltage UE//UA 1500V.
The working ranges of the DC/DC converter modules range from 16V to 36V and the modules are also equipped with active transient protection, which safely eliminates the specified overvoltage (for 20mS) of two times the nominal input voltage of up to 48V and transients of up to 1000V//50µs.
The module has diverse voltage and current monitoring circuits which are set to low levels at the binary outlets if:
- the input voltage is <UE min or the output voltage is > IA
- the output voltage < or > UA planned, the light diode will extinguishon the front plate
- the load current exceeds the maximum value 4A, or the input voltage fails to reach the UE value, the status shall be stored and issued via a binary outlet.
The MTBF of the DC/DC-converter module is > 350,000 h, which meets the life requirements for railway equipment of 24/d for 30a.
The 19” 3HE insert meets the requirements for vehicle applications and 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.
