Keystone KTEB-232-UV-IS-N-P-DP 2 x F32T8

The KTEB-232-UV-IS-N-P-DP is a universal voltage ballast, rated 120-277V. That is the whole reason to stock this one across a mixed portfolio: the same part goes into a 120V tenant space and a 277V corridor or warehouse circuit without you carrying two SKUs. Input voltage is the one thing you do have to confirm at the fixture before you wire it, because the ballast covers the range but your branch circuit is whatever it is.

No. The KTEB-232-UV-IS-N-P-DP is non dimmable and has no wireless control, so it is a straight on/off ballast. Wiring it to a dimmer or feeding it from a dimming control channel will not give you level control and risks the ballast. If the space needs dimming or scheduling at the fixture, you need a dimming ballast or an LED retrofit with a driver that takes a control signal, not this one.

Ballast only. No LED module is included, and no lamps come with it, so budget the two F32T8 lamps separately if you are doing a full relamp while the fixture is open. It ships with standard wire leads, meaning you land it with wire nuts to the existing fixture wiring rather than plugging into a connector.

Yes. The KTEB-232-UV-IS-N-P-DP is not flagged as restricted from sale in California, so it can go on a California job. Worth knowing for the spec sheet on that job: it does not carry CEC Title 20 registration, DLC or DLC Premium listing, Title 24 JA8 compliance, or Energy Star. If the project is chasing a utility rebate or an energy code credit that requires one of those, this ballast will not carry it.

Depends on how long you are keeping the fixture. Putting the KTEB-232-UV-IS-N-P-DP in keeps the fixture on F32T8 fluorescent lamps, which is the cheapest way to get a dead troffer back on the same night with no socket or wiring changes. An LED conversion is where you go if you want the energy reduction and the longer relamp interval, but that means either ballast-bypass tubes with the sockets rewired or a full LED retrofit kit, and this ballast carries no DLC listing, so it earns no utility rebate. Property managers with a building full of matched T8 troffers usually keep the ballast swap for one-off failures and save the LED conversion for a planned floor-by-floor project.

Keystone KTEB-232-UV-IS-N-P-DP. Reading the designation: 232 is two F32T8 lamps, UV is the 120-277V universal input, IS is instant start. That is the number to give a distributor or put on a PO, and it is the number to match when you are standardizing the ballast across a building so every fixture takes the same spare off the shelf.
