SYLVANIA

SYLVANIA Optotronic OT30W/CS1050C/UNV/SD/L Dimmable LED Ballast 120/277V

SKU CH-NHN6-Q4ZKB

Dimmable LED power supply with selectable output currents up to 1050 mA for 120-277 VAC dry and damp locations

  • Constant current output provides stable LED performance
  • StepDIM bi-level dimming allows adjustable light levels
  • Selectable output currents suit different LED arrays
  • Universal 120-277V input works across power systems
  • Class 2 power unit rated for dry and damp locations

LED Driver for Dry and Damp Locations

The SYLVANIA Optotronic OT30W/CS1050C/UNV/SD/L is a constant current LED power supply rated for 30 watts. It suits installers who need a Class 2 unit for indoor or sheltered outdoor fixtures. Selectable output currents allow matching to different LED modules. This unit is not for buyers who need a non-dimmable driver or higher wattage capacity.

StepDIM Bi-Level Dimming and Universal Voltage

The StepDIM function provides bi-level dimming through the line voltage wires without extra control cables. A 120 to 277 VAC input range covers standard North American service voltages. Class 2 construction limits output voltage and current for safer handling during installation. The design omits a separate low-voltage dimming interface.

Fixed 1050 mA Maximum Output Current

The selectable current settings top out at 1050 mA, so LED arrays needing more drive current cannot use this model. Bi-level dimming only switches between two preset levels rather than continuous adjustment. Installers requiring 0-10V or DALI control protocols must choose a different driver. The 30 watt limit also restricts the total connected LED load.

Questions about this item

What does the 120-277VAC input range mean for installation?

The driver accepts any mains supply between 120 V and 277 V, so the same unit works on standard 120 V circuits and on 277 V commercial lighting circuits without rewiring.

What physical space and mounting does the OT30W/CS1050C/UNV/SD/L require?

The compact case fits inside typical luminaire channels or junction boxes; it mounts via integral tabs or side flanges and is rated for dry and damp indoor locations.

How do you set the output current on this driver, and what mistake do installers make?

Use the selectable-current dip switch or jumper to choose the required level up to 1050 mA; the common error is powering the driver before confirming the selector matches the LED module’s rated current.
