DA3-22M
Universal dimming actuator, 2-channel
EN
Characteristics
- DA3-22M is a universal dimming 2-fold actuator enabling control of brightness intensity of dim-
mable light sources of the type ESL, LED and RLC with power supply 230V.
- DA3-22M has two MOSFET controlled outputs 230V 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 raill EN60715.
