Philips Lighting 913710414801 – Frequently Asked Questions

1) Will this Philips core and coil ballast run a 400W metal halide lamp, or is it HPS only?
HPS only. The Philips 913710414801 core and coil CWA ballast is built for a single 400W high pressure sodium lamp carrying ANSI code S51-M169. A 400W metal halide lamp uses a different ANSI designation and a different ballast circuit, so it will not start or run correctly on this unit. Match the ANSI code printed on the lamp to S51-M169 before wiring it in.
2) What line voltages can this 400W HPS ballast be wired to?
It is a multi-tap unit: 120, 208, 240, 277 or 480 volts at 60 Hz. You pick the tap on the input leads to match the branch circuit, which means one part number covers a 277V commercial lighting circuit and a 480V industrial feed alike. Nominal input current runs 3.85 A at 120V, 2.2 A at 208V, 1.95 A at 240V, 1.75 A at 277V and 0.95 A at 480V.
3) What fuse size should I use on a 400W HPS core and coil ballast?
Recommended fuse values track the tap you land on: 10 A at 120V, 6 A at 208V, 5 A at 240V, 5 A at 277V and 3 A at 480V. Those allow for the starting current, which is 2.91 A at 120V down to 0.72 A at 480V. Nominal input power at full load is 460 W for the 400 W lamp, so size the branch circuit with that draw in mind, not the lamp wattage alone.
4) How far can the ballast be mounted from the lamp in a remote installation?
Remote mounting is permitted, but the maximum ballast to lamp distance is 2 feet. That is short, so a pole base or remote enclosure more than a couple of feet from the socket is out. For a pole light where the ballast sits at the base and the lamp is at the top, this ballast is the wrong choice.
5) Do I need to buy a capacitor and ignitor separately for this CWA ballast?
A CWA circuit needs both, and the matched components are specified: capacitor 7C550P24RA, 55 MFD rated 240V at 105 C, and ignitor LI501-H4 also rated 105 C. The capacitor body measures 1.85 in on the oval diameter and 3.70 in tall, which is the clearance you need inside the fixture housing or ballast tray. Substituting a different microfarad value will throw the lamp off its trapezoid.
6) Can this HID ballast be used in an outdoor parking lot or roadway fixture?
Yes, it is rated suitable for outdoor use in an HID fixture, with UL Insulation Class H (180 C) windings and UL temperature code 1029D. It is UL Recognized rather than UL Listed, so it is a component intended to be installed inside a fixture or enclosure, not a standalone weatherproof assembly.
7) Why choose a CWA magnetic ballast over a reactor or lag type for a 400W HPS fixture?
CWA (constant wattage autotransformer) holds lamp wattage steady through line voltage swings, with deviation kept within the trapezoid limits and a 0.9 power factor. A reactor or lag ballast is simpler and cheaper but lets lamp output drift with the line, and reactor types only work on one specific line voltage. This unit's multi-tap input and regulation make it the choice where the feed is long, loaded, or shared with motor loads.
8) Will the light come back on by itself after a power blip?
No. Automatic restart is not a feature of this ballast, and HPS lamps need to cool before they will restrike in any case. If your site needs instant light after a momentary outage, plan on quartz restrike within the fixture or a separate emergency source.
9) What open circuit voltage and short circuit current should I see when bench testing this ballast?
Nominal open circuit voltage is 190 V, with an acceptable test window of 176 to 214 V. Secondary short circuit current should read 6.0 to 7.4 A. Open circuit input current runs 1.73 A at 120V through 0.41 A at 480V. Hipot withstand is 2000 V for one minute or 2500 V for two seconds. Readings outside those bands point to a failed coil or a miswired tap.
10) How is this Philips ballast identified for cross-referencing an old kit I am replacing?
The base model is 71A8453 and the factory order description reads CORE & COIL HID 71A8453001D. If the ballast coming out of the fixture carries a 71A8453 base number and drives a 400W HPS lamp, this is the matching core and coil.
11) What are the lead wires like and how much slack do I have for wiring it into a ballast tray?
Leads are stranded, 12 inches long by color, with a 0.5 mm strip length specified. Twelve inches gives you enough to reach terminals inside a typical fixture housing but not much more, so position the ballast accordingly. Core size is 4 x 4 with 2 coils and the piece weighs 7.743 kg, so the mounting tray or bracket has to carry that load.
12) Does this ship as a single ballast or in a multi-pack?
One piece per pack, one pack per outer box, so an order quantity of one gets you a single ballast. It drives one lamp, so a fixture with two 400W HPS lamps needs two units plus two capacitor and ignitor sets.
