Advance 71A8251001D – Frequently Asked Questions

1) Can I dim this 250W HPS magnetic ballast for a parking garage schedule?
No. This is a non-dimmable magnetic core-and-coil ballast, so it runs at full output whenever the circuit is energized. For step lighting or scheduled reduction you have to switch the fixture or the circuit, not the ballast.
2) Does the Advance 250W HPS ballast kit come with the capacitor, or do I order that separately?
It ships as a kit with the capacitor rated at 35 MFD. If you are replacing only a failed cap on an existing installation, that 35 MFD value is the one to match; mismatching microfarads on an HPS circuit will cause hard starting or short lamp life.
3) What does Class P thermal protection mean on an HID ballast, and does this one have it?
Class P protection is built into this Advance ballast. It is a thermal cutout in the winding that opens if the ballast overheats, then resets as it cools, which keeps a failing lamp or a hot fixture from cooking the coil. On enclosed outdoor fixtures in warm climates that is the feature that keeps a nuisance failure from becoming a burned ballast.
4) Is this Advance HID ballast approved for use in Canada as well as the US?
It carries UL recognition and a CSA certificate, and it is RoHS compliant. Manufactured in the USA. That combination covers specs that call for both US and Canadian listing on commercial and municipal jobs.
5) Will the lamp put out full rated lumens on this ballast, and how much does it load the circuit?
Ballast factor is 1.0, so a 250W S50 lamp runs at its full rated output rather than a reduced level. Power factor is 0.9, a high power factor design, which keeps line current and system losses down compared with a normal-power-factor ballast on the same circuit.
6) Is a pulse start HPS ballast different from a probe start unit, and which do I need?
All high pressure sodium ballasts use a starter to fire the lamp, and this Advance unit is a pulse start design that sends a high voltage pulse to strike the arc. Probe start applies to certain metal halide lamps only, so it is not an alternative here. If your fixture is HPS with an S50 lamp, pulse start is what it takes.
