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.
