The HUB DC is used as ballast to operate I/O modules of the C|Logline LON, Modbus and BACnet range to rectify and smooth 24 V AC (alternating voltage). It supplies at the output a smoothed direct voltage of about 33 V DC (with 24 V AC at the input). To convert the supply voltage of C|Logline LON, Modbus and BACnet modules from a 24 V AC operation to DC operation (24 to 36 V DC) reduces the thermal load in the I/O modules and extends the service life of the included components. The device is designed as half-wave rectifier with common earth point (input A2 = output 0 V) to be directly used in 24 VAC systems.
