Description
Keystone SmartCurrent Flex Constant Current LED Driver, 100W Max Power, Universal 120-277V Input, Programmable Fixed Output Current 280-2800mA (factory default 2800mA), 10-55Vdc Output, Analog 0-10V Dimming
Keystone SmartCurrent Flex 100W Programmable LED Driver with High Surge Protection (KTLD-100-UV-P2800-55-VDIM-LT2-HSP)
The Keystone SmartCurrent Flex KTLD-100-UV-P2800-55-VDIM-LT2-HSP is an industrial-duty, high-output linear programmable constant current LED driver engineered for high-bay luminaires, industrial strip retrofits, vapor tights, and high-wattage linear ambient fixtures. Supplying up to 100 watts with an adjustable output current range up to 2800mA, this driver combines universal 120–277V input, smooth 0–10V architectural dimming down to 1%, enhanced high-surge protection (HSP), and an extended “LT2” low-profile metal housing designed for demanding commercial and industrial environments.
Key Features & Performance Benefits
- Field & Benchtop Programmability: Precise constant current output programmable up to 2800mA in 1mA increments via Keystone’s SmartCurrent configuration tool without requiring high-voltage AC power during setup.
- High Surge Protection (-HSP): Built-in enhanced surge immunity safeguards internal circuitry and connected LED arrays against severe electrical transients, switching spikes, and dirty utility lines in industrial environments.
- Wide Forward Voltage Window: Provides reliable constant current regulation across a broad 10–55V DC Class 2 output range to support dense multi-board linear strings and high-efficiency LED arrays.
- Continuous 0–10V Dimming: Integrated architectural analog dimming delivers flicker-free, smooth illumination adjustment down to 1% minimum output.
- Extended “LT2” Enclosure: Heavy-gauge, low-profile linear metal housing optimized for thermal dissipation in enclosed wireway raceways, troffers, and industrial high-bay fixture profiles.
- Safety & Compliance: UL 8750 Recognized, Class 2 Output, UL Class P listed, Type HL rated for hazardous locations, FCC Title 47 Part 15 Class A compliant, with built-in open-circuit, short-circuit, over-voltage, and thermal foldback protection.

Frequently Asked Questions
What does "KTLD-100-UV-P2800-55-VDIM-LT2-HSP" stand for in Keystone's catalog?
"KTLD" designates Keystone Technologies LED Driver, "100" indicates 100W maximum capacity, "UV" stands for Universal Voltage (120–277V), "P2800" denotes Programmable output current up to 2800mA, "55" specifies the 55V maximum DC forward voltage, "VDIM" indicates 0–10V dimming, "LT2" designates the extended linear metal housing, and "-HSP" specifies the High Surge Protection upgrade.
What is the primary benefit of the "-HSP" (High Surge Protection) option?
The "-HSP" model integrates heavy-duty surge suppression directly inside the driver enclosure, providing heightened immunity against line voltage surges, inductive load kickback, and electrical transient spikes commonly encountered in industrial facilities, warehouses, and manufacturing plants.
Can this driver be installed in fixtures without connecting 0–10V dimming wires?
Yes. If dimming control is not used, individually cap and insulate the purple (DIM+) and gray or pink (DIM−) control wires. The driver will operate at 100% of its programmed output current as a standard non-dimming constant current supply.
