Advance 71A7801001D – Frequently Asked Questions

1) Will this Advance 50W ballast kit run my 50 watt high pressure sodium lamp?
It runs one 50W high pressure sodium lamp, and the ANSI code is S68. Match that S68 designation on the lamp itself, not just the wattage, because HPS lamps are coded to the ballast that fires them. Ballast factor is 1, so you get rated lamp lumens. It will not run metal halide or mercury vapor lamps.
2) Can I wire this HPS ballast kit on 277V, or is it 120V only?
Both. The Advance 71A7801001D is a dual voltage kit rated 120/277V at 60 Hz, so the same part works on a 120V single phase circuit or a 277V lighting branch circuit typical of commercial buildings. You select the voltage by the input lead you land, so it is one SKU to stock for mixed-voltage buildings. It is not rated for 208, 240, or 480V.
3) Will this ballast fit inside my existing pole head or wall pack housing?
The core assembly measures 3.94 by 2.81 by 2.20 inches and the kit weighs 4.3 lbs. That is a compact magnetic core and coil, but HPS ballast trays vary, so measure the free space in the housing and check your mounting hole pattern against the core before you pull the old one. The weight matters if you are hanging it off a tray in an overhead area light.
4) Does this ballast kit come with the capacitor, or do I have to order that separately?
It is a kit, and the capacitor is specified with it at 5 MFD. When you replace a failed HPS ballast, the capacitor is the part most often overlooked and it has to match the core, so a kit saves you sourcing it on its own. Verify the rating stamped on the old cap reads 5 MFD before reusing anything from the existing fixture.
5) Can I put this HPS ballast on a dimmer or a lighting control panel?
No dimming. This is a non-dimmable magnetic HID ballast, so it runs full output only. Control it by switching the branch circuit, a photocell, or a contactor in a lighting panel. If a facility spec calls for dimmed exterior lighting, an HPS magnetic ballast is the wrong direction and the job wants an LED retrofit instead.
6) What is the difference between a pulse start and a standard reactor HPS ballast?
This one is pulse start, meaning an igniter sends a high voltage pulse to strike the arc rather than relying on the lamp electrode alone. For HPS that is the normal arrangement and it is what lets the lamp restrike as it ages. The practical point for a buyer: your lamp and your old ballast must both be the pulse start S68 type, since a lamp coded for a different ballast will cycle or fail to start.
7) Will a 0.9 power factor ballast hurt my building's electrical load numbers?
0.9 is high power factor, so the ballast draws close to the real power it consumes and keeps line current down. On a parking lot or perimeter run with a dozen fixtures on one circuit, that is the difference between fitting the circuit and pulling a bigger conductor. Utilities and energy codes in many jurisdictions expect high power factor on HID.
8) Is this Advance ballast made in the USA for buy-American procurement?
Country of origin on the 71A7801001D is the USA, which is what government, education, and healthcare procurement offices usually need documented on a submittal. Note that country of origin alone is not a Buy American Act determination; your contracting officer makes that call.
