The RP Series expansion light modules with power distribution capability and low-voltage blind modules have a built-in power supply that can accommodate a nominal input voltage of 230 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 Series 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.
