Advance 71A7891001D – Frequently Asked Questions

1) Will this Advance 50W ballast run my high pressure sodium lamp, or do I need to match an ANSI code?
Match the ANSI code on the lamp. The Advance 71A7891001D is built for HPS lamps carrying ANSI code S68, which is the 50W high pressure sodium designation, and it drives one lamp at 50 watts. If your lamp is stamped anything other than S68, this is the wrong ballast, even at the same wattage. It will not run metal halide or mercury vapor lamps.
2) Will this HPS ballast fit inside my existing pole-top or wall-pack housing?
The ballast measures 3.94 x 2.81 x 2.20 inches and weighs 5.6 pounds. Check the clear space in the fixture ballast tray against those three numbers before you order, and make sure the tray or mounting plate will carry 5.6 pounds of core and coil, which is heavier than the electronic ballast or LED driver some retrofits use.
3) Does this ballast have built-in thermal protection, and is it UL listed for a commercial fixture?
Class P thermal protection is built in, which cuts the ballast out if the case temperature climbs too high and resets when it cools. The ballast is UL recognized and CSA certificated, and it is RoHS compliant. That combination is what most commercial and institutional specs ask for on an HID fixture retrofit.
4) What comes in the Advance 50W HPS quad kit besides the ballast core?
It is a kit, so the capacitor is part of it: 5 MFD, which is what sets the lamp current along with the core and coil. If you are replacing only a failed capacitor on an existing ballast, you need a 5 MFD unit rated for the same circuit, not the whole kit. Ignitor-based pulse start is how the 50W HPS lamp strikes.
5) Can I put this 50W HPS ballast on a dimmer or a photocell-plus-dimming control?
No dimming. This is a magnetic HID ballast and it is not dimmable, so it runs the lamp at full output whenever it is energized. Photocell or timeclock switching of the whole circuit is the normal control method for HPS area and security lighting. If the job calls for dimming or daylight harvesting, an HPS magnetic ballast is the wrong direction and the fixture should be converted to LED.
6) I manage parking lots and walkways with old 50W sodium fixtures. Is this the right replacement ballast to standardize on?
For 50W HPS heads it is a sensible single stock item, because the quad-tap input covers 120, 208, 240 and 277V so you do not have to inventory one ballast per voltage across a portfolio. The requirement is that every fixture uses an S68 50W sodium lamp. Mixed-wattage lots (70W, 100W, 150W sodium) each need their own ANSI-matched ballast.
7) What does the 0.9 power factor mean for how many of these I can put on a 20A lighting circuit?
A 0.9 power factor is high-power-factor, so the ballast draws close to the real load in current rather than the inflated draw a low-power-factor unit pulls. Ballast factor is 1, meaning the lamp runs at its full rated 50W light output. For an MRO or facilities load calculation, use the 0.9 figure with your operating voltage, since 277V operation draws far less current per fixture than 120V for the same wattage.
8) What is the Advance part number to order for the 50W HPS S68 quad kit, and where is it made?
Order Advance 71A7891001D, the 50W HPS S68 quad-tap magnetic kit. Country of origin is the USA, which matters on public and government jobs with domestic sourcing language in the spec.
