The dimming photocontroller JL-254 series is applicable to control any independent LED
home/street lighting with DALI driver automatically in accordance with the ambient natural lighting
level, as well as remote control by using a gateway box (JL-254P or JL-254V) connected to a
smart phone either iOS and Andriod OS with Bluetooth communication, while connected to the
smart control (JL-254C) with Zigbee communication.
This smart control JL-254C is designed with microprocessor circuits with IR-filtered silicone sensor,
a heavy duty surge arrester (MOV) 40kA is provided to protect the lamp from inrush current as well
as impulse by lightening.
Further, a preset 3-5 seconds time-delay prevents excessive operation due to spotlight or lightning
during the night time. A heavy duty relay supports the work life of over 15,000 cycles,.
This smart control JL-244C provides twist lock terminals and signal contacts, in 7P, meeting the
requirements of ANSI C136.41-2013, as well as being listed by UL under the Standard for Plug-In,
Locking Type Photo control for Use with Area Lighting ANSI/UL773.
Constant On/Off Dimming Standard program for LED output keeping the field lit with constant
lighting level, in accordance with the natural sunlight level detected. When the natural lighting is
higher than 110% of the rated level, hot line will be disconnected to keep LED fixture as zero
Midnight Dimming Standard program for LED output lowered to an adjustable percentage to
save power after midnight until about 1 hour before dawn time, as well as reduce light pollution to
LED Decay Compensation Standard program for LED output partially reserved and to be used
for compensating decay over a work time up to 13 years. It will extend the work life of a LED fixture
Emergency Cycling When necessary, a visitor may run the LED
