PRODUCT DESCRIPTION
MICRO-1CV is a 1-channel Pulse Width Modulation (PWM) Constant Voltage (CV) LED dimmer. It can be powered from a constant
voltage (12 ÷ 48) Vdc SELV power supply and is suitable for driving a load such as Strip LED and White/Monochrome LED modules
at constant voltage. The dimmer can be controlled via Normally Open (N.O.) push-button, analog input 0/1-10V, or via a 10 kΩ
potentiometer; the automatic detection of the local control that ensures the proper functionality related to the type of the connected
control.
MICRO-1CV can deliver a maximum output power up to 78 W (@12V) or 150 W (@24/48V) and has the following protections:
over-voltage and under-voltage protections, reverse polarity protection, input fuse protection and open-circuit protection.
Through the Push Menu are possible to configure multiple parameters including dimming frequency, Fade In/Out time values and
minimum brightness level.

    IAGRAM FOR BUTTON MICRO-1CV can be controlled via Local Control with Normally Open (N.O.) push-button or voltage-free dry contact. The N.O. push push-button will be identified after 5 quick presses. In push-button mode, function memory is always active. To connect the MICRO-1CV to local control, simply connect the push-button to the INPUT terminal. The following image shows the indicated connection diagram for short distances (<10 m).
  • Page 5 For longer distances (>10 m), it is recommended to use an N.O. dry contact relay module, connected between the "Input" terminal of the MICRO-1CV and the power source (e.g. mains voltage 230 Vac). Figure 4 shows an example of a Local Command wiring diagram recommended for long distances.
