Switching off standby
with DALI
Luminaires with electronic ballasts usually need a
closed-circuit current, even when the lighting system is
turned off or is in standby mode. This energy consump-
tion adds up, but can be conserved using the KNX/DALI
gateway Twin plus: by automatically cutting off power
to the electronic ballasts. After the lighting is turned off
and as soon as all electronic ballasts in the defined area
are no longer needed for lighting, the ballasts can be
disconnected from the power supply via a command from
a switch actuator controlled for this purpose. If one or
more luminaires are in operation, the switch actuator first
restores power to the electronic ballast, and the gateway
dims the luminaire to the required brightness level.
