DIMMING TECHNOLOGIES

230 V Dimmers with phase-cut output for 230 V AC loads
Light dimming is achieved by “phase-cutting” whereby cutting-off part of the voltage waveform reduces the RMS voltage fed to the lamp. When the cut-off part is the initial part of each half cycle it is called Leading Edge dimming, while a dimmer that cuts off the final part is Trailing Edge dimming. The two methods are each suitable for dimming different types of load: Trailing Edge is, in general, more suitable for electronic transformers for low-voltage lamps (halogen or LED); Leading Edge is more suitable for electromagnetic transformers for LV lamps, and for CFLs. Both methods can be used with 230 V halogen lamps and incandescent lamps. 0-10 V
Use to expand the maximum number of 0-10 V channels of an exiting system or for interfacing with another 0-10 V system PWM
Dimmer for controlling 12…24 V DC LED strips
PWM: “Pulse Width Modulation” is an electrical power regulation technique that consists of modulating the width i.e. the on-time duration of a series of pulses such that, the longer the pulse, the greater the power applied to the load. This type of modulation applies exclusively to direct current, which is used particularly for the dimming of DC powered LED strips. In this case, the dimmer is positioned downstream of the DC power supply.

COMMUNICATION PROTOCOLS

Bluetooth Technology YESLY is Finder’s system for a modern and efficient smart home
Simple and flexible – Finder’s YESLY system ranges from offering you the simple control of home functions such as lighting, electric blinds and shutters, room temperature and electric locks… through to the creation of customised scenarios, controllable from smartphones or through voice assistants, both locally or remotely.
YESLY is a scalable system that readily accepts the integration of new control points and new features as needed and without invasive intervention, even integrating into existing systems and buildings with a legacy of outdated technology.
YESLY is the Finder system for a modern and efficient smart home.
Thanks to the new Finder YOU app you can configure and use all of Finder’s smart home devices
Turn on the lights, open the blinds and adjust the room temperature, all from the same app COMMUNICATION PROTOCOLS
Bluetooth Technology Example of 230 V AC phase-cut dimmer display screen (15.71 or 15.21.8.230.B300) The following parameters can be set:

Minimum light value
Switching time (time it takes the dimmer to ON/OFF)
Dimming time (time it takes the dimmer to reach the extremes of brightness in manual dimming)
Scene time (time it takes the dimmer to reach the required % value recalled by a scenario)
Memory (when turned ON, the dimmer returns to the light value previous to being turned off)
Reset after blackout (when power returns, the dimmer reaches the light value before the blackout)

Choice of phase-cutting:

Leading Edge
Trailing Edge
AUTOMATIC

With the AUTOMATIC function the dimmer will flash the lamp load twice to check the best phase-cut method for adjusting the light level

COMMUNICATION PROTOCOLS
KNX Technology The KNX system is the world’s most advanced standard for the automated management of high-end building installations. This technology can be used to control: lighting, shutters, alarms and video surveillance, heating, ventilation and air conditioning, water management, energy optimisation, energy meters, appliances and audio systems.
KNX is approved as: – European Standard (CENELEC EN 50090 and CEN EN 13321-1)

International Standard (ISO/IEC 14543-3)
Chinese Standard (GB/T 20965)
US Standard (ANSI/ASHRAE 135)

Type 15.10 Master Dimmer Multifunction Master for the control of one or more Type 15.11 Slaves or other drivers with 0 -10 V input
Features:

230 V AC 50/60 Hz power supply with automatic frequency recognition
Multifunction (with or without light intensity memory, including a special function with memory for CFL lamps)
Linear adjustment
Dimming speed adjustment
Staircase light function with early switch-off warning by dimming the lamps
Auxiliary terminal for the safe disconnection of 1-10 V ballasts for signals < 1 V
Module width 17.5 mm, 35 mm rail mounting (EN 60715)

MASTER DIMMER TYPE 15.10 AND SLAVE DIMMER TYPE 15.11
This is the recommended configuration; the Master controls one or more Slaves up to a maximum of 32 units. Pushbuttons (max. 15, if luminous); a short press performs ON/OFF control, while a longer press adjusts the brightness level. Each Slave can drive a different type of load. MASTER DIMMERS AND ELECTRONIC TRANSFORMERS OR BALLASTS 0-10 V
Using only the Master Dimmer it is possible to control electronic transformers or ballasts with 0-10 V/1-10 V input (respecting polarity). In this application it is recommended to interrupt the Live to the ballast via contact 14. This solution ensures complete disconnection of the ballast for signals < 1 V.
Note: When using terminal 14, check that the maximum peak current of the ballast does not exceed 30 A 230 V AC. Otherwise, use a contactor or power relay.
