![]() This can be due to short-circuits, overloaded switching loads or too high an ambient temperature. If the CPU temperature reaches a critical point, the outputs of the device are switched off. If the motor is not suitable, this can damage both the motor and the Dimmer Extension! Only use this if you have experience with speed control of motors by phase cutting and if it is known that the motor type used can be controlled by leading edge phase cut and that no dangerous voltage peaks occur. However, only certain motors are suitable for this. The Dimmer Extension can also be used for speed control of motors via leading edge dimming. In such a case, use other lamps or a higher number per channel, or switch them off via an additional relay contact. However, some low-power LED lamps are so sensitive that this can cause occasional flashing or slight glowing. The voltage disappears with even a low load, as there is virtually no power available here. This results in a voltage being measurable at the outputs even when the outputs are switched off, especially without a load. The outputs of the Dimmer Extension are equipped with capacitors for interference suppression. If possible, test different LED luminaires for dimming quality before purchasing a large quantity. It is advisable to use high-quality luminaires, which guarantee consistent quality and long-term availability. There may also be batch-related differences in LED lamps. However, characteristics such as the dimming curve, dimming range, and flicker-free dimming can differ for every luminaire. In principle, all mains voltage LED luminaires marked as dimmable can be dimmed with the Dimmer Extension. However, for low-voltage halogen lamps, the transformer must be dimmable. Generally, incandescent lamps are always dimmable, even if they are not labeled as dimmable. Of all luminaires, incandescent lamps are the easiest to dim, this category can also include Halogen lamps and these are an alternative when the highest quality of light is desired and the energy consumption is acceptable. If in doubt, the manufacturer of the luminaire can provide information on the load characteristics (whether inductive or capacitive) and the recommended dimming method. The ballasts, LED drivers, electronic transformers etc. **A magnetic transformer must be loaded with at least 80% of it's capacity! ![]() *The sum of the nominal load of the ballasts, LED drivers or transformers is relevant, not the nominal load of the actual light. Low voltage halogen lamps with magnetic transformer (MLV) Mains voltage LED fittings (retrofit, LED bulbs) Low voltage halogen lamps with electronic transformer (ELV) Only use luminaires that marked as dimmable! Please observe the recommended dimming type and load limits! The Extension starts after switching on the power supply, and the status LED will flash orange after a short time when the connection to the Miniserver is established. However, a single-phase supply is also possible.Įnsure sufficient air circulation to allow the generated waste heat to dissipate, especially at high workloads. In case of large loads or multiple dimmers, it is advisable to spread the load across several phases as shown in the wiring example. The Dimmer Extension is installed on a DIN rail in a suitable enclosure.Ĭonnect the power supply and Link communication to the Miniserver.Ĭonnect the loads to the outputs as shown in the example above. The Dimmer Extension features 4 Output channels for dimming suitable mains voltage luminaires.Įach channel can be set to trailing edge or leading edge dimming, the Dimmer Extension is thus suitable for resistive (incandescent), capacitive (ELV) and inductive (MLV) loads.Īdditionally, 8 digital inputs for 24V are available.ĭatasheet Dimmer Extension 120V Table of Contents
