505-12 Power Supply
Description
The DMP 505-12 Series Power Supplies are regulated, power limited, switching power supplies. The 505 Series are
rated for 12VDC @ 5 Amps maximum. Each power supply includes a transformer, battery leads and is mounted in an
enclosure. Each power supply provides connections for AC input, DC output, and a standby battery. Also included
are a low AC input LED indicator, a low standby battery LED indicator, AC trouble and battery trouble relays, and
on-board transient protection for the AC input and the DC output. The 505-12LX includes two Model 867 Style W
Notication Modules.
Mounting the Enclosure
Mount the power supply metal enclosure in a secure, dry location to protect the unit from damage due to tampering
or the elements. It is not necessary to remove the PC board or transformer when installing the enclosure.
Mounting Optional NAC Modules
The power supply enclosure can accommodate the addition of two NAC modules for powering various listed
notication appliances. Use either the DMP Model 865 conventional Class A NAC module, the Model 866 conventional
Class B NAC module, or the Model 867 LX-Bus NAC module. Install any of the modules inside the enclosure using the
three hole mounting conguration. Plastic standoffs are provided with each module that attach to the enclosure.
