Product Description - PL-AT-TW1 – PoE powered LED driver
This LED driver in a compact module can be installed 328 ft away from a PoE injector or switch using Cat-5e cable. In
most areas PoE installations do not require licensed electricians The PL-AT-TW1 is installed between a PoE switch and a
LED panel light. The PL-AT-TW1 has low standby power, and is configurable for 3 ma, 7 or 1 ma of LED current
requirements. The wide output voltage range of 9 to 5 volts fits the NEC / NFPA codes for low voltage wiring and
allows almost any LED fixture to be used.
Intended for use with any 8 2.3at, 8 2.3af or passive Poe injector or switch, the output current automatically adjusts to
match the PoE source. If connected to a 8 2.3af switch, the output current will be 3 ma, with 8 2.3at switches it will
be 6 ma. If you work with passive injectors – we have a 8 2.3at bypass jumper to force higher power operation.
When used with a 8 2.3bt switch – two devices can be connected in series to use all 4 pairs of the Ethernet cable and
double the wattage on one PoE port. Boost jumper allows 1 mA output in 8 2.3at or passive mode.
The attached LED can be turned on/off and Dimmed from a SNMP type PoE switch or injector, or from a momentary
switch like the AL-WS-M.
Specifications for PL-AT-TW1
Power input 44 to 56 volts 8 2.3af or 8 2.3at or Passive PoE
RJ45 Input Connector RJ45 standard connector
mode A power only. Mode B passthru
RJ45 Output Connector
RJ45 standard: input pairs 4&5 and 7&8 are
connected to pairs 1&2 and 3&6 on this output
connector to allow two devices on one CAT-5e cable
RJ45 LED status Green means PoE active, Amber means 8 2.3at
On/Off/Dim switch The output RJ45 connector also has the connection
to a RH-253 or AL-WS-M switch for On/Off/Dim
LED Output Voltage 9v to 5 v 35 watts max
Output Power
a) with 8 2.3af max current 36 ma = 12 watts
b) with 8 2.3at max current 66 ma = 23 watts
c) jumper selection for 1 mA in AT mode
Auto power switching Current reduced to 36 mA if 8 2.3af switch
detected increases to 66 or 1 ma if 8 2.3at
Inrush limiter Built in – automatic

Smart Keep Alive
Keep Alive is the current needed to keep a PoE switch port from shutting down. Simple keep alive burns 5 mW when the
LED is off. Our Smart Keep Alive reduces this to 1 mW using a 25% duty cycle.

PoE Power Input
Use a PoE switch or injector to supply power. It can be mode B 8 2.3af, 8 2.3at or 4 pair 8 2.3bt for up
to 25 watts. Every 8 wire cat-5e cable can carry 2 separate PoE power sources. Lets call them PoE 1
and 2. Each PL-AT-TW1 accepts power from PoE 1 and passes PoE 2 to the output connector
PoE 1 Power Input
PoE 1 is the power for the LED attached to this device. It can be mode A 8 2.3af, 8 2.3at or 2 pair
8 2.3bt for up to 25 watts.
PoE 2 Power Input
PoE 2 is the optional power from a 8 2.3bt switch. It is passed thru the device to the next device in the
chain to provide power to a second PL-AT-TW1 attached to the output connector. The output RJ45
moves the mode B input to Mode A output so no crossover is required.
Dimmer / Switch In
The device has a Switch input with a 1 k pullup to 3.3v. When Open the LED is on, when closed the LED
is off. If a PWM signal is applied ( For example from a AL-WS- 1 v) then the LED can be dimmed. See
the AL-WS- 1 v for a PWM wall switch. Use a RH-253, AL-WS-M momentary switches, or use a simple
On/Off switch. Connect the switch between pins 7&8 of the output connector to create a On/Off/Dim
switching ability. If a momentary switch is used, then each press will toggle the light on/off. If PoE
power is cut and then started again – the Light will always come on. Hold the switch to cause the light
to dim. Release to keep the color that was requested.
If two PL-AT-TW1 are connected onto one CAT-5e cable to the power source, see our application note
for how to have one wall switch control 2 PL-AT-TW1
