LED Dimmer, 4-fold, 315 W/VA, MDRC
Multichannel universal dimming actuator optimized for dimming of retrofit LED lamps
(LEDi). Also suitable for dimming of incandescent lamps, low-voltage halogen lamps with
conventional or electronic transformers, 230 V incandescent halogen lamps and dimmable
halogen energy-saving lamps. Automatic load detection (deactivatable). One separate
N-terminal per channel. Channel bridging possible in order to increase the maximum load.
Outputs can be switched in parallel in groups as required. Minimum load: 2 W. Manual opera-
tion on the device is possible also without bus voltage or in unprogrammed state. One LED
UD/S 4.315.2.1
control button per channel (including status indication) for ON and OFF switching as well as
for up and down dimming. Programming of the device is possible without connecting 230 V
supply voltage. Comprehensive test and diagnostic functions via the i-bus® Tool.
Fast parameterization in the ETS by means of copyable channel templates. With integrated
bus coupler.
Rated power at 230 V ~:
• 230 V ~ incandescent and halogen lamps: 4 x 315 W/VA to 2 x 500 W/VA.
• Dimmable 230 V ~ LEDi: 4 x 315 W/VA to 2 x 500 W/VA in trailing edge mode,
• 4 x 120 W/VA to 2 x 200 W/VA in leading edge mode.
• Inductive L-transformers with LED/low-voltage halogen lamps:
4 x 315 W/VA to 2 x 500 W/VA.
• Electronic C-transformers with LED/low voltage halogen lamps:
4 x 315 W/VA to 2 x 500 W/VA.
• Electronic LC transformers with LED/low-voltage halogen lamps:
4 x 120 W/VA to 2 x 200 W/VA.
Recommendation: Always use bulbs of one type and manufacturer
