Most units are microprocessor based with multi-functional alpha numeric display. All fan trays are using axial long life DC-fans (low acoustic noise!) which are individually controlled. Fan speed is variable from 1200 to 3000rpm. WIENER fan trays can be outfitted with network interfaces (CAN, Ethernet, RS232, USB). In combination with WIENER power supplies and bins the complete system monitoring and control of all parameters is given.
