Description
The voltage range covers 24, 48, 60, 110, 125 and 220 V DC, and for 24 V the module has a power of 1500 W. The modules accept an input of 85–300 V AC, so they withstand deep mains sags. Efficiency reaches 97%, cooling is natural and fanless, which means the cabinet has no wear part and does not collect dust. The enclosure is chosen for the site, from 5U/12U racks to wall-mounted WRS and floor-standing cabinets. The VIDI2 or VIDI+ controller transmits data via Ethernet, Modbus, IEC 61850, SNMP and RS-232, which simplifies connection to the substation process control system. The system is supplemented with EIM inverters of 1–24 kVA, single-phase or three-phase, also with N+1 redundancy. Compliance with EN 50124-1 and EN 50121-4/-5 relates to railway use, while EN 61439-1/-2 and IEC 62368-1 cover panel assembly and safety.
How to choose
Start with the nominal battery voltage and the total load and charging current, after which the number of MHE modules is determined as the required power plus one spare. The 5U/12U racks suit telecom cabinets, WRS small sites, and floor-standing cabinets substations. If the substation uses the IEC 61850 protocol, the VIDI controller supports it. When a single powerful rectifier up to 1000 A without modularity is needed, consider RDC.
