Philips Lighting 913710405501 – Frequently Asked Questions

1) Will this Philips 1000W HPS ballast run a metal halide lamp instead?
No. The Philips 913710405501 core and coil kit is built for 1000W high pressure sodium lamps only, ANSI code S52, one lamp per ballast. The ignitor and the CWA circuit are matched to that S52 lamp; a 1000W metal halide lamp uses a different ANSI designation and will not be operated correctly here. Check the ANSI code printed on the lamp sleeve before you wire it in.
2) What fuse size should I use on a 1000W HPS CWA ballast?
Philips gives recommended fuse values per tap: 25 A at 120V, 15 A at 208V, 12 A at 240V, 10 A at 277V and 6 A at 480V. Starting current is higher than running current (7.8 A at 120V down to 1.9 A at 480V), which is why the fuse is sized above the 9.28 A nominal draw on the 120V tap.
3) Does the capacitor and ignitor come with this ballast, or do I order them separately?
The kit is matched: capacitor RW1626020 at 26 MFD, 525V, rated 90 C, and ignitor LI571-H5 rated to 105 C. If you are replacing only a failed component in an existing fixture, those are the part numbers to match. The capacitor case measures 1.75 in across the oval and 4.25 in high, which matters when you are fitting it back into a tight ballast tray.
4) Can I remote mount this ballast away from the fixture?
Yes, remote wiring is allowed, with a maximum of 15 feet between ballast and lamp. Go beyond that and starting and lamp regulation are no longer within the ballast's rating. Leads are stranded wire, 12 inches long, with a 0.5 mm striplength, so plan on splicing into your remote run inside a box.
5) Will this fit an outdoor pole-mounted area light housing?
It is rated suitable for outdoor use and carries UL insulation class H (180 C), so it is appropriate for area, site and roadway fixtures where the ballast tray sees weather and heat. Core size is 4 1/4 x 6, and net weight is 13.903 kg per piece, which is the figure to check against a pole or bracket that was originally built around a lighter core.
6) What does CWA mean and why would I pick it over a reactor ballast for 1000W HPS?
CWA stands for constant wattage autotransformer. It holds lamp wattage within the rated trapezoid as line voltage swings, and the autotransformer lets one unit accept taps from 120V all the way to 480V. A simple reactor or lag ballast has no autotransformer, so it only works when your line voltage already matches the lamp's requirement and it passes line voltage variation straight through to the lamp. For 1000W HPS on a commercial service where voltage sags under load, the CWA is the one that keeps light output steady.
7) Does this ballast restart a hot HPS lamp automatically after a power blip?
No. Automatic restart is not a feature of the 913710405501. After a momentary outage the lamp has to cool before it will strike again, which is normal for HPS. If the space needs light during that cooldown, plan on a separate quartz restrike or an emergency fixture rather than expecting the ballast to handle it.
8) Is this a UL Listed ballast or UL Recognized?
UL Recognized, marked ULR, with UL temperature code 1029C and class H (180 C) insulation. Recognized means it is a component approved for use inside a listed luminaire, not a standalone listed assembly, so it goes into a fixture or an enclosure rather than being installed bare. Temperature marking across the five taps is C/C/C/C/C.
9) What Philips base model number does 913710405501 correspond to for cross-referencing an old ballast?
The base model is 71A8753, ordered as CORE & COIL HID 71A8753001. If the label on the ballast you are pulling out of the fixture reads 71A8753, this is the matching 1000W HPS CWA replacement.
10) What open circuit voltage should I read when testing this ballast without a lamp?
Nominal open circuit voltage is 437 V, with an acceptable test range of 390 to 476 V. Open circuit input current runs 3.9 A at 120V down to 0.96 A at 480V. Secondary short circuit current is 6.24 to 7.63 A. Those are the numbers to compare your meter reading against when deciding whether the ballast or the lamp is the failed part.
11) How does this 1000W HPS ballast ship, single unit or a carton of several?
One ballast per pack, one pack per outer box, so an order quantity of one gets you a single core and coil unit weighing 13.903 kg. Ballast factor is 1, meaning full rated 1000 W lamp output, not a reduced-output version.
