Online 3:1 3Phase 380VAC UPS PM 3910
The PM860 series of UPS’s run under a double conversion design principal. The unit is designed to run from a 3-phase 380VAC input and delivers a single phase 220 / 230 VAC output at 50Hz.
Double conversion technology offers the user the best possible level of power protection. The incoming mains is converted directly into DC. This DC power is used to charge the batteries and to drive the inverter, which in turn runs the load. Should the mains fail the batteries will simply carry on driving the load.
The units have a built in Static By-Pass feature which enables the machine to transfer the load to normal mains under certain conditions. There is no break on the output on transfer to or from the mains.
