Product Description
48 VDC rapid start fluorescent light ballast designed to operate two F54 T5HO (High Output) fluorescent lamps. It features optically isolated electronic ON/OFF control via the standard low voltage RJ11 modular cable. When the inside two wires (red/green) of the RJ11 connector are shorted, the light
goes on. When they’re opened, the light goes off.
This feature allows for easy remote switching and interfacing with occupancy sensors such as the Sensor DT2-54-R-S-53VDC Switch CM-6-R-NPS.
• DC power to the ballast is never interrupted (unlike conventional AC ballasts that interrupt the power to turn the lights off).
• Designed for optimal performance with the Nextek NPS-1000 Power Gateway, the KT2-54-R-S-53VDC can also be used with any DC power supply within the specified
operating voltage range.
• Up to nine KT2-54-R-S-53VDC ballasts may be powered by a single NPS-1000 (eight ballasts if optional storage batteries are used).
• Lighting fixtures can be ordered from light fixture manufacturers with this ballast installed, or it may be installed on-site.
