LTP (Low Power DC System)

The LTP wall & rack mount system provides DC voltage to a load while charging external batteries.  This flexible system can accomodate rectifiers or inverters.  If the AC mains supply fails, then the batteries will supply power to the load.  The LTP system is suitable for charging many types of batteries.  It can also be used as a direct power supply without batteries. 

The modular and scalable design with hot pluggable rectifier and inverter modules assures low Mean Time to Repair and future expansion.
