For models: AC-225U and AC-225IPU
These models come without a transformer. When using a third-party
transformer, please make sure that it is rated for at least 50 W (16.5 VAC @
3A).
AC-225U and AC-225IPU have a maximum 50 W power consumption, which
means that it requires 3.0 A. This rated power is divided in the system, as
follows:
1) 300 mA for the Lead Acid Battery Charger
2) 980 mA total for four readers (when MD-D02 is used)
3) 900 mA total for the four outputs
In cases where the installation requires more power (for example high rated
magnetic locks), we recommend using an external power supply for the lock.
