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.
• 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
