Shop filtered and regulated door power supplies in 12VDC and 24VDC, with battery backup, fire alarm interface, and multiple output options. In stock at Commercial Door Hardware and shipping the same day.

Why Order Power Supplies from Commercial Door Hardware
Commercial Door Hardware supplies door hardware for schools, healthcare facilities, offices, retail and institutional buildings, carrying power supplies, electrified locks, strikes, exit devices, holders, closers and hinges from Sargent, Von Duprin, Corbin Russwin, Accentra, LCN and Norton.
Power supplies are the part of an electrified opening that gets specified last and causes the most callbacks. The two figures that matter, inrush current and voltage at the device under load, are both easy to get right beforehand and expensive to diagnose afterwards, because the symptoms always look like a faulty lock.
