Philips Lighting 913700556609 – Frequently Asked Questions

1) Will the Philips 71A8271001D core and coil kit run a 250W high pressure sodium lamp?
That is exactly what it is built for. The 71A8271001D is a magnetic HID core-and-coil assembly rated for a single 250W HPS lamp on a CWA (constant wattage autotransformer) circuit, ANSI code S50. One lamp per unit, so it is a one-for-one ballast replacement in a 250W HPS fixture. It will not operate metal halide or mercury vapor lamps.
2) What line voltages can this Philips HID ballast kit be wired to?
It is a multi-tap ballast: 120, 208, 240 or 277V at 60Hz. You pick the tap at install with the color-coded leads. Nominal input current runs 2.5A at 120V, 1.47A at 208V, 1.25A at 240V and 1.09A at 277V, with nominal input power of 295W at a 0.9 power factor. Recommended fuse values follow the same tap order: 7/4/4/3A.
3) Does this ballast kit come with the capacitor and ignitor, or do I order those separately?
Both are included and matched to the core and coil. The capacitor is Philips 7C350P24RA, 35 MFD rated at 240V, 1.65 in oval diameter by 3.7 in high, with a 105C rating. The ignitor is LI501-H4, also rated 105C. A CWA circuit will not start an HPS lamp without both, so this saves sourcing them one at a time.
4) Can I remote mount this 250W HPS ballast away from the fixture head?
Remote wiring is allowed, but the run is short: maximum ballast-to-lamp distance is 2 feet. That covers a ballast box mounted in a pole base or behind a fixture housing, not a ballast located across a building. Lead wires are 12 inches long, color coded, stranded, with a 0.5 mm strip length.
5) Is this HID ballast rated for an outdoor pole or wall pack fixture?
It is rated Suitable for Outdoor Use, which is what you want for site, roadway and pole-mounted HPS fixtures. Insulation is UL Class H (180C) with UL temperature code 1029B and a B temperature marking on all four taps. It is UL Recognized (ULR), meaning it is a component intended for installation inside a listed fixture or enclosure rather than a standalone device.
6) Will the lamp come back on by itself after a power blip with this ballast?
No. Automatic restart is not a feature of the 71A8271001D. After an interruption the HPS lamp has to cool before it will restrike, the normal several-minute HID restrike delay. If a facility needs instant light after a dropout, plan on a separate quartz restrike fixture or emergency egress lighting rather than expecting this ballast to hot restart.
7) Why choose a CWA ballast instead of a reactor or lag type for a 250W HPS fixture?
CWA (constant wattage autotransformer) holds lamp wattage steady through line voltage swings, with deviation held within the trapezoid, and gives a 0.9 power factor with 1.0 ballast factor so the lamp puts out its rated lumens. Open circuit voltage is 187V nominal (170 to 205V test range). Reactor and lag ballasts are cheaper and smaller but tolerate far less line variation, which is why CWA is the usual pick for outdoor area and roadway lighting on long feeders.
8) How many ballasts come in a box when I order the Philips 913700556609 kit?
One. The kit is packed one piece per pack, one pack per outer box, so each order unit is a single core-and-coil assembly with its matched capacitor and ignitor. For a multi-fixture relamp and reballast, order one per fixture.
9) What current should I expect on startup and under a lamp fault when sizing the branch circuit?
Starting current on the 250W HPS core and coil runs 1.61A at 120V, 0.89A at 208V, 0.80A at 240V and 0.68A at 277V. Open circuit draw is 1.53/0.95/0.77/0.63A and short circuit input ranges 1.16-1.74/0.64-0.96/0.56-0.85/0.49-0.74A by the same tap order. Secondary short circuit current is 3.65 to 4.45A. Size fusing per the recommended 7/4/4/3A values for the tap you land on.
