Key Features and Advantages

The VPS 12004-102-03 features active power factor correction (PF>0.98) and galvanic isolation meeting EN 50124-1 insulation standards. Its redundant topology ensures seamless switchover during catenary voltage drops. Integrated short-circuit protection limits fault current to 150% nominal within 2ms. The aluminum housing dissipates heat efficiently while withstanding 5g vibration (EN 61373). SIL 2-certified control logic prevents unsafe output conditions during communication failures.

Application Areas

Critical for metro train auxiliary systems, the VPS 12004-102-03 powers HVAC and lighting under unstable catenary conditions. High-speed rail networks utilize its CANopen interface for real-time energy monitoring. Tram systems benefit from the wide input voltage range during pantograph arcing events. Renewable energy integration uses the unit for DC microgrid stabilization in rail depots.
