Frequently asked questions
Common questions about LUTRON from 3G Electric.
What input voltage range do Lutron LED drivers accept?
The Lutron LED drivers supplied by 3G Electric accept 120 to 277V AC input. This range covers common commercial and industrial supply voltages in North America and other regions, allowing the drivers to be used without external step-down transformers. Both constant voltage and fixed output constant current models operate on this input range. Output specifications vary by model: constant voltage drivers provide 12V DC or 24V DC, while constant current drivers provide output currents of 0.50 A or 0.70 A across defined voltage windows.
What is the difference between Lutron constant voltage and constant current LED drivers?
Lutron constant voltage drivers, such as SKU 38AY07 and 38AY08, deliver a fixed output voltage (12V DC or 24V DC) and are used with LED fixtures or systems that require a regulated voltage supply. Lutron fixed output constant current drivers, such as SKU 60AT10 through 60AT14, deliver a fixed output current (0.50 A or 0.70 A) across a specified voltage range, which is typical for LED arrays rated for constant current operation. Both types accept 120 to 277V AC input and are Class 2 rated. Selection depends on the fixture or system specification.
What is the Lutron PP-DV power pack used for?
The Lutron PP-DV is a hard-wired power and relay control unit that converts 120 to 277V AC input to 24V DC output. It is compatible with the Lutron LOS W series and supports LED, fluorescent, halogen, and incandescent lighting technologies. The unit provides relay switching and power for control circuits, making it suitable for installations where low-voltage control signals need to operate higher-voltage lighting loads. It is used in commercial and institutional lighting systems that require centralized or zone-based control.
Are Lutron LED drivers Class 2 rated?
Yes. The Lutron LED drivers listed in 3G Electric's inventory are Class 2 units. Class 2 classification refers to the output circuit's power and voltage limits under applicable safety standards, which allows for certain installation and wiring methods. This rating applies to both the constant voltage drivers (SKU 38AY07, 38AY08) and the fixed output constant current drivers (SKU 60AT10 through 60AT14). Specifiers should confirm that the Class 2 output limits are compatible with the connected load and installation requirements.
What dimming method do Lutron LED drivers use?
The Lutron LED drivers supplied by 3G Electric incorporate a proprietary dimming method. This means the dimming protocol is specific to Lutron systems and may require compatible Lutron controls or interfaces for proper operation. The drivers are not necessarily compatible with third-party dimming protocols unless explicitly stated. For system design, verify compatibility between the driver, the control, and the fixture. Technical documentation for each SKU provides the relevant dimming specifications.
What output current and voltage options are available in Lutron fixed output constant current drivers?
Lutron fixed output constant current drivers in the 3G Electric inventory are available with output currents of 0.50 A and 0.70 A. Output voltage windows include 15 to 38V DC and 30 to 54V DC, depending on the model. Maximum power output ranges from 26.6 W to 40 W. For example, SKU 60AT10 provides 0.50 A at 30 to 54V DC with 27 W maximum output, while SKU 60AT11 provides 0.70 A at 30 to 54V DC with 40 W maximum output. Selection depends on the fixture's forward voltage and current requirements.
