NSi 2002 – Frequently Asked Questions

1) How much LED load can the NSi 2002 photocell switch?
On LED loads the 2002 is rated 1040-1385VA, scaling with the supply voltage across its 208-277VAC range. For comparison it handles 2080-2770VA of ballast load and 3470-4620W tungsten. LED and ballast loads are inrush-heavy, which is why the LED figure is well under the incandescent rating. Total up the driver VA on the circuit, not the lamp wattage, before you commit to it.
2) How does the NSi 2002 photocontrol mount, and do I need a junction box?
It mounts on 1/2 inch conduit with a stem and swivel fitting, so it threads onto a 1/2 inch nipple or conduit stub rather than sitting in a box. Six inch leads come out of it for wiring into the fixture or box behind. The swivel lets you aim the sensor cell away from the lamp it controls, which is the usual cause of a photocell cycling itself on and off all night.
3) Can this photocell be used outdoors in cold climates?
It is built for exterior service: Lexan housing that stands up to weather and UV, and an operating range of -40 to +140 F. That covers northern winters and hot roof-level installs on flood and patio lighting.
4) At what light level does the NSi 2002 turn lights on and off?
Turn-on happens at 1 to 5 footcandles as dusk falls, and turn-off at 3 to 15 footcandles at dawn. A 2 minute timing range keeps a passing car's headlights or a brief cloud from flipping the lights. Sensing is done by a Cadmium Sulphide cell.
5) Is this photocontrol UL listed for commercial jobs?
The NSi 2002 is cULus Listed, which covers both the US and Canadian listings inspectors look for on exterior lighting control.
6) Does the NSi 2002 photocell add measurable load to the circuit?
No meaningful load. It draws under 1 watt in standby, so a facility standardizing dozens of dusk-to-dawn fixtures isn't adding anything worth counting to the panel.
7) What part number do I order for the NSi 208-277V swivel photocontrol?
Order NSi Industries model 2002. It is the single configuration of the Lexan stem and swivel photocontrol at 208-277VAC, so there are no finish or sensitivity options to specify.
