The DC 3000 is a DC/DC-Converter converting either 110 Vdc or 220 Vdc to 24 Vdc with an output current of 100 A. Applications include: 24 Vdc voltage for supplying the control-technology systems in nuclear and non-nuclear power stations, the chemical industries and power substations. The switch-mode power supply units are normally fed from the secure 110 V or 220 Vdc supply (high operating reliability). Programming is simple with the controls and indicators installed on the front panel. It is designed as a compact 19" module of 4 height units. in parallel using the n+1 principle.
