The addition of the MX-12-VR Module enables dual 12VDC and 24VDC output capability.With the MICROAXS 600 Series power supply output set at 24VDC for locking devices and components, the addition of the MX-12-VR provides a separate 12VDC, 500 mA output for 12VDC Access Controllers and readers or other devices. The need for separate power supplies for 12VDC and 24VDC requirements within the same system is eliminated.
