Philips Lighting 913701115201 – Frequently Asked Questions

1) Will the Philips 913701115201 ballast run a 50W metal halide lamp, or is it sodium only?
High pressure sodium only. The 913701115201 core and coil ballast is built for one 50W HPS lamp carrying ANSI code S68, and it ships with the ignitor (LI551-H4) that HPS lamps need. A 50W metal halide lamp uses a different ANSI designation and a different ballast circuit, so it will not operate correctly on this unit.
2) Can I wire this Philips 50W HPS core and coil ballast to 277 volts, or do I need a separate part number for each voltage?
One part number covers four line voltages. It is a multi-tap ballast accepting 120, 208, 240 or 277V at 60 Hz, so you pick the tap in the field. Nominal input current runs 0.61 A at 120V, 0.35 A at 208V, 0.31 A at 240V and 0.26 A at 277V, with nominal input power of 66 W on any tap.
3) How far can the ballast be mounted from the HPS lamp if I remote-mount it in a pole base or separate enclosure?
Remote wiring is allowed, but the run is short: maximum ballast-to-lamp distance is 2 feet. That rules out pole-base mounting for a fixture up on a mast arm. It works where the ballast enclosure sits right next to the lamp compartment.
4) I am replacing a failed ballast in an old HPS wall pack. What do I need to match to be sure this Philips unit drops in?
Match four things: the lamp is 50W HPS with ANSI code S68, the core is a 3 X 4 two-coil frame, the supply is one of 120/208/240/277V at 60 Hz, and there is room for the capacitor at 1.25 x 2.25 in. Leads are 12 inch stranded wire. If the old ballast is a different ANSI code or a single-voltage 480V unit, this is not the replacement.
5) Is this Philips core and coil ballast OK for an outdoor area light, and what temperature class does it carry?
It is rated suitable for outdoor use in exterior HID fixtures. Thermally it is UL Insulation Class H (180 degrees C) with UL temperature code 1029A and an A temperature marking on all four voltage taps. It is a UL Recognized component, marked ULR, meaning it is intended for installation inside a listed fixture rather than used as a standalone assembly.
6) What fuse size should I use on the line side of a 50W HPS HX-HPF ballast?
Recommended fuse values are 3 A at 120V, 2 A at 208V, 2 A at 240V and 1 A at 277V. Size to the tap you actually land on. Starting current is modest, 0.65/0.37/0.32/0.3 A across the same taps, and open circuit input current runs 1/0.57/0.5/0.45 A.
7) What does HX-HPF mean on an HID ballast, and how is it different from a reactor or CWA ballast?
HX-HPF is High Reactance High Power Factor. It uses a capacitor on the line side to pull power factor up to a nominal 0.9, which keeps input current low (0.61 A at 120V here) compared with a low power factor reactor. Ballast factor is 1, so the lamp gets its full rated 50W. What it does not give you is the wide input voltage tolerance of a constant wattage autotransformer design; lamp wattage regulation on this unit is held within the trapezoid rather than the tighter CWA window. On a stable 120 to 277V utility feed that is normal practice for 50W HPS.
8) Will a 50W HPS lamp on this ballast restrike immediately after a brief power dip?
No. Automatic restart is not a feature of this ballast, so after an outage or a voltage dip that drops the arc the lamp has to cool before it will re-ignite. On a security or roadway application where instant light matters after a blink, plan for a quartz restrike fixture or a separate emergency source.
9) How much does the Philips 50W HPS core and coil ballast weigh, and how many come in a box?
Net weight is 1.937 kg per piece, and it ships one per pack, one pack per outer box. Worth knowing before you spec a remote enclosure or a ballast shelf that has to carry it.
10) What are the open circuit voltage and hipot test values for this HID ballast if I am bench testing it?
Open circuit voltage is 125 V nominal, with an acceptable test window of 115 to 135 V. Hipot withstand is 2000 V for one minute or 2500 V for two seconds. Secondary short circuit current should land between 1.3 and 1.9 A.
