Smart Light
SL-750
FEATURES
-
Easy to Install – Once Smart Light is installed 10-20cm apart from the fence wire, the Unit is automatically calibrated and ready for operation.
-
No Contact Failure – There exists absolutely no contact failure between Smart Light and fence wire. This makes the Unit ideal for polywire or polytape fences.
-
No Voltage Drop – Smart Light never causes voltage drop on the fence wire. This makes the Unit particularly suitable for the fences with a small capacity energizer.
-
Multi-Level Indicator – ① Normal, ② Low, ③ Very Low, and ④ No Voltage levels are indicated by a combination of ultra bright LED flashes.
-
Animal Repellent – Ultra bright LED flashes can prevent animal access.
-
High Visibility – Provides day and night visibility (750m at night).
-
Solar Powered – Rechargeable battery system ensures long-term maintenance free.
INSTALLATION EXAMPLES
For T-posts, no additional grounding is required as the post itself can act as a ground rod. For wood or plastic posts, grounding is required. When using a galvanized wire for grounding, connect one end to the Bracket and bury the other end in the moist ground about 30cm.
One of the simple installation is to mount the Unit on a separate steel post. We recommend 3/4 to 1 inch galvanized or stainless steel pipe as the post.

FOUR STEP FENCE VOLTAGE INDICATION
Smart Light is not a simple electric fence light indicating the presence of the fence voltage. Smart Light analysis the state of the electric fence voltage into four steps. These steps are indicated by the flashing pattern of LEDs. The Reference Voltage is reset by the current fence voltage when the switch is pushed.

INSTALLATION STEPS
SL-750 CLIP is easy to install without any tools by following these steps.
-
Place the Clip on the electric fence wire. The Clip is easily fastened to the electric fence wire by pushing the clip hook against the wire.
-
Insert the Unit into the Clip by sliding the Rail Mount of the Unit into the Shoe Mount of the Clip.
-
Adjust the direction angle of the Unit so that the LED flashes are well observed.
-
Then, as a final step, energize the fence and push the switch at the bottom.

LONG-TERM PERFORMANCE TESTING OF SMART LIGHT INDICATORS (VIDEO)
Smart Light SL-750 and SL-750 Clip are undergoing long-term testing at our test facility.
-
#1 and #2 are initial versions of SL-750 and SL-750 Clip, respectively, both installed five years ago.
-
#3 and #4 are improved versions of SL-750 and SL-750 Clip, installed three years ago.
-
#5 and #6 are commercial versions of SL-750 and SL-750 Clip, installed one year ago.
They have been working as intended for many years in Korea’s harsh four-season climate.
