Keystone KTEB-228HE-UV-PS-SL-CP – Frequently Asked Questions
1) Will this Keystone T5 ballast work on 277 volt commercial power?
Yes. The KTEB-228HE-UV-PS-SL-CP is universal voltage, 120 to 277V, so the same part covers 120V tenant spaces and 277V commercial lighting circuits. For a property manager standardizing stock across buildings on different service voltages, that means one ballast on the shelf instead of two.
2) Can I dim the fixture with this ballast?
No. This is a non-dimmable T5 ballast, and it has no wireless or networked control capability. If the space needs dimming or occupancy-based level control, this is the wrong part, and no external dimmer on the line side will make it dim safely.
3) Does this ballast come with lamps or does it include an LED module?
Ballast only. No LED module is included and it is not an LED driver, so you'll order F28T5 fluorescent lamps separately. It also isn't an add-on accessory device, it's the primary ballast for the fixture.
4) How does this Keystone ballast wire into the fixture?
It ships with standard wire leads, so you're making splices to the existing fixture wiring with wire nuts or push connectors rather than plugging into a connector block. Electricians replacing a failed ballast in an existing T5 troffer should plan on stripping and splicing line, neutral, ground and the lamp leads.
5) Should I replace a failed T5 ballast or convert the fixture to LED?
If the fixture and lamps are otherwise sound and the space has no dimming or control requirement, dropping in this electronic T5 ballast is the quick fix: universal 120-277V input, wire leads, 1 lb unit, and it keeps the existing F28T5 lamps. Go the LED route instead when you need dimming or control, since this ballast is non-dimmable, has no wireless control, and includes no LED module.
