​Catalog Number: PSD0108-UNV-IV
​Type: Single-pole or 3-way (meaning it can control a light from one or two locations).
​Voltage: Universal voltage (UNV), rated for both 120VAC (10A) and 277VAC (5A).
​Color: Ivory (-IV at the end of the model number).
​Compatibility: Designed for LED and CFL lighting that supports a 0-10V dimming signal.
​What makes this different from a standard dimmer?
​Most standard home dimmers vary the voltage on the power line itself. This device, however, has extra wires to send a low-voltage (0-10V) signal to the light's driver, telling it exactly how much to dim. This provides smoother dimming and is often required for large office lighting or modern architectural LEDs.
​Important Safety Note: Because this device supports 277V (common in commercial buildings) and requires specific low-voltage wiring, it is highly recommended that it be installed by a qualified electrician
