ページを印刷するDIMMING PROTOCOL
ALS600T is available in 120 or 277 volts with a dimmable integral or remote driver. The driver
is available with 0-10V dimming capabilities. Consult factory for other dimming protocols
available. The following applies to 0-10V dimming interfaces. A 0-10v fluorescent dimmer will
not dim the LEDs.
Technical Requirements For Control Equipment
• The light output of the LEDs operated by the controllable LED driver is controlled by DC voltage
applied to the control input leads (grey and violet). The actual response curve of LED driver
current versus control voltage.
• The control device must be capable of accepting, or sinking, the DC current flow from the
driver. The DC current from the driver that must be sinked by the control circuit is
150uA (+/50% for isolated dim interfaces, up to 1.5mA for non-isolated dim interfaces).
• If the control bus is opened, or if the control device internally opens the control bus under
some conditions, the voltage on the control bus will then be a function of the drivers, which is
10-15V. Maximum light output will be delivered under this condition.
• If the control bus is shorted either by a mechanical switch in the control or by the circuitry of
the control device, or inadvertently in the wiring, the current on the control bus will be less
than 1.5mA.
• As can be determined from the two items, simple two-level operation of the drivers can be
achieved by proper usage and application of a simple open/closed switch on the control bus
with maximum light being achieved when the switch is open and minimum light with the
switch is closed.
• The driver is intended to be used with control voltages between 0-10VDC volts peak maximum
on the driver control leads.
• Control equipment intended to control more than one driver must be capable of sinking the
current supplied to the control bus by the maximum number of drivers specified for the control
device. At any given level setting it must maintain control bus voltage constant within a range
of ±5% as the number of drivers connected to the control bus varies from a minimum of one
driver up to the maximum number specified for the control device.
• Driver of various ratings may be mixed on the same control system.

0-10V DIMMER RATINGS
The stated VA (volt-ampere) rating is the rated capacity of the dimmer which includes the
electronic transformer heat losses and the lamp load. A transformer dissipates less than 20%
of the connected load as heat. The lamp load plus the transformer loss determine the dimmer
capacity required. See the example below.
TRAXXX-E
20% of Lamp Load lost as heat
(19.2W = 20% of 72W)
Dimmer must be rated to at least 91.2W
