BEST PS-490 – Frequently Asked Questions

1) What is the output of the BEST PS-490 power supply?
The PS-490 puts out 24VDC regulated at 0.5A. That 0.5A ceiling is the number that matters on the job: add up the current draw of every electrified device you intend to run from it, and if the total exceeds half an amp you need a larger supply or a second unit.
2) Will the PS-490 power supply work with Stanley door closers, or only BEST?
Both. The PS-490 is sold as a replacement part for compatible BEST and Stanley door closer systems, and it is referenced as a Stanley Door Closer parts and accessories component. BEST and Stanley door hardware share this accessory line, so a service tech carrying one PS-490 covers either brand of electrified closer, provided the device runs on 24VDC and draws no more than 0.5A.
3) Is the PS-490 rated for commercial use or is it a residential-grade transformer?
Commercial. The PS-490 is classified as a commercial-grade replacement part and is built for commercial door hardware installations, which is where electrified closers on offices, schools, healthcare corridors, and municipal buildings live. It is not a residential doorbell-style transformer.
4) Can I use a 12V power supply instead of the PS-490 on a BEST electrified closer?
No. The PS-490 supplies 24VDC, and a device specified for 24V will not operate correctly, or at all, on 12V. If the closer or its electric hold-open, electric strike, or release device calls for 24VDC, match it with a 24VDC supply. Check the voltage stamped on the device itself before substituting anything.
5) Is the PS-490 the whole closer or just the power supply?
Just the power supply. The PS-490 is a standalone 24VDC 0.5A unit, sold as a replacement part for door closer systems, not a closer body, arm, or mounting kit. If you are replacing a failed electrified closer, you order the closer separately and reuse or replace this supply as needed.
6) I manage several buildings with BEST electrified door closers. Can I stock one part number for all of them?
If the electrified closers and accessories in those buildings run on 24VDC and each circuit stays within 0.5A, the PS-490 covers them as a common spare. It is the same part across compatible BEST and Stanley closer systems, so one part number serves a mixed BEST/Stanley portfolio. Where an opening runs multiple devices off one supply, total the draw first, since 0.5A is the limit on a single unit.
7) How many options or finishes does the PS-490 come in?
One configuration only. PS-490 is a single part number with no finish, voltage, or size choices to specify, so there is nothing to select beyond quantity.
