Universal dimming actuator, 2-channel DA3-22M

DA3-22M is a universal dimming 2-fold actuator enabling control of brightness intensity of dimmable light sources of the type ESL, LED and RLC with power supply 230 V.

Description

  • DA3-22M has two MOSFET controlled outputs 230 V AC, maximum load is 2x 400 VA.
  • Option of connecting an external temperature sensor.
  • Each output channel is independently controllable and addressable.
  • Type of light source is set by a switch on the front panel.
  • By setting the min. brightness potentiometer on the front panel, fl ashing of diff erent types of light sources is eliminated.
  • DA3-22M is equipped with two inputs 230 V AC, which can be controlled by mechanical switches (buttons, relays). Inputs are galvanically connected to potential L, which is permanently at the terminals IN1 and IN2.
  • Buttons on the front panel, you can manually switch on or off the corresponding output.
  • Electronic overcurrent and thermal protection - switch off output in case of overload short circuit and overheating.
  • The power supply (potential L) must be protected by a protective element corresponding to the power input of the connected load, e.g. a safety fuse.
  • During installation, it is necessary to leave on each side of the actuator at least half the module space for better cooling.
  • DA3-22M in 3-MODULE version is designed for mounting into a switchboard on DIN rail EN60715.
