AC to DC Converter
Full wave bridge rectifier
Transformer
Function/Application
Transforms 120 volts AC to 24 volts AC. (To get 24 volts
DC, use with 8WCON, AC to DC converter.) Typically
used as a power supply for electrically-operated locks.
Function/Application
Converts AC (alternating current) to DC (direct current)
for locking circuit applications. (Typically used with
8W599 transformer.)
8WBU-1-A
Standard plate
8WBU-1-N
Narrow plate
Function/Application
Normally open push-button switch provides momentary
switch closure when pressed. Typically used to momentarily
energize electrified locks or strikes or used as a request-to-
exit switch on access control systems.
