Power Supply Requirements
CRUZcontrol operates from a nominal supply voltage of 24 volts DC. The wiring methods and
componentry used are such that a Class 2 power supply should be used. This limits the output power to
a total of 100 VA. The current required for each CRUZcontrol Logic Assembly is 67mA, which allows for
up to 53 zones per power supply. There is also a limit on the maximum number of Logic Assemblies that
can be in one continuous string, based on the cable length from the power supply to the first Logic
Assembly:
More than one string of Logic Assemblies can be connected to a power supply, up to the maximum of 53
zones.
