The RP controller expansion light modules with power distribution capability, low-voltage blind modules, and SMI blind modules have a built-in power supply that can accommodate a nominal input voltage of 230 VAC at 50/60 Hz. Light modules without power distribution capability can accommodate a nominal input voltage of 100 to 277 VAC at 50/60 Hz.
The built-in power supply is an integrated AC/DC module, which features a full-wave rectifier, a galvanically isolated DC output, and incorporated electronic components for overvoltage protection, overload protection, and EMI filtering.
With the RP controller expansion module's Power Input galvanically isolated from electronics of the module, the risk of damage due to earth ground currents is reduced.
For the DALI light modules, the built-in power supply is used to convert the AC mains voltage to 18 VDC, which is supplied to the Light outputs for control of the lights.
For the 0-10V light modules, the built-in power supply is used to convert the AC mains voltage to 10 VDC, which is supplied to the Light outputs for control of the lights.
For the low-voltage blind modules, the built-in power supply is used to convert the AC mains voltage to 24 VDC, which is supplied to the Blind outputs for control of the blinds.
For the SMI low-voltage blind modules, the built-in power supply is used to convert the AC mains voltage to 24 VDC, which is supplied to the Blind outputs for powering of the blind motors.
For the SMI high-voltage blind modules, the built-in power supply is used to convert the AC mains voltage to 18 VDC, which is the SMI control voltage.
