SYLVANIA Osram 79376-A Optotronic OT30W/CS1050C/UNV/SD/L Ballast 120/277V case of 10

30 W Constant-Current LED Driver Pack

This case contains ten Osram Optotronic OT30W units designed for LED luminaires that require a steady 1050 mA output. Each driver accepts a universal 120-277 VAC input, making it suitable for commercial and residential installations in North America. The StepDIM bi-level dimming function allows two preset light levels without extra control wiring. Installers who need a Class 2 power unit for dry or damp locations will find this pack convenient.

30 W Capacity with Selectable Current Headroom

The 30 W rating powers LED arrays that draw up to 1050 mA at the corresponding forward voltage, covering many mid-output modules and retrofit kits. When the connected load exceeds the 30 W limit or requires a current setting not offered by the selectable outputs, the driver cannot regulate properly and a higher-wattage model becomes necessary. The bi-level StepDIM feature provides basic dimming but does not support continuous 0-10 V or DALI control schemes.

Universal-Voltage Case-of-Ten for Simplified

Each driver mounts inside a fixture or junction box and connects directly to 120 V or 277 V branch circuits without a separate transformer. The Class 2 designation eases inspection compliance in dry and damp environments. Buyers who need continuous dimming protocols, higher wattage per channel, or single-unit packaging will not be served by this specific pack.
