Do you need to convert that AC transformer to DC? Well, here is an economical way to do just that!
The ROFU #1005 (without leads) or ROFU #1006 (with 6″ leads) Full Wave Bridge Rectifiers
They are a lot more than what meets the eye! These two ROFU models will accept up to 10A Max, Up to 1000V (higher than most)
There are full wave rectifiers and half wave rectifiers, with an electric strike it may not matter as much if you use a half wave rectifier, but if you try to use one with an electromagnetic lock the magnet will not function correctly. The pictures below show you why:
This drawing (above) shows a half wave rectifier. It removes the negative flow and leaves you with only the top positive half of the wave, this will give you quick burst of power.
The full wave rectifier (above) convert the entire negative flow to positive flow, ensuring the current flow continues with no gaps.
For electro-magnetic lock installations, ROFU always recommends using a “full-wave” bridge rectifier, anything less would create breaks in the power (the bursts in the 1st drawing), and thus putting the holding force into question. It is also important that installers know that they can use “cheap” rectifiers, but also there is a bigger possibility that they will not cancel the entire negative flow, which means it would allow “AC” power to leak through, and possibly damage the magnetic lock or the PC board.
For fail secure electric strike installations, you could use a half wave rectifier and shouldn’t have power issues, but we always recommend using a full wave bridge rectifier.
