24VAC to VDC 5 Amp AC/DC Converters with adjustable output
between 1V and 18V
Tiny switchmode 24VAC / 5A power supply offers much higher
efficiency and lower ripple than the linear versions. The biggest application
of these is to power 3.3V, 5V, 8.4V, 9V, 10V, 12V, 14V, 15V, 16V devices in
24VAC installations.

Connection
Wire leads, input and output
DC input
When using a direct current input, connect the plus
and minus to the input terminals, it doesn't mattery which is the plus or
minus, since we put a full bridge rectifier on the input, which will sort it
correctly.

<p> The following table gives a snapshot of a few
voltages and output currents that gives an idea of the capabilities. The
converter is designed to use 24VAC input, but can be operated at lower input
voltages depending on the output voltage and current:</p>

* 50/60Hz ripple will go down as the current goes down,
as it is due to the size of the input capacitors.
