Power Supply w/Line Conditioner • The power supply is the heart of the Millenium System. It can support between 15 DCD boards (power for locks and other devices provided by local power supplies. • In addition to providing board power, the power supply has an integrated line conditioner which generates the biasing voltage necessary for RS-485 communications and to filter out any noise or interference on the communications cabling.
Power Supply Spec’s • Input: • 120 VAC, 60 Hz, 2 AMPs unswitched circuit (P/N PS1-100212-001) • 240 VAC, 50 HZ, 2 AMPs unswitched circuit (P/N PS1-100213-001) • Output: • 13.8 VDC, @ 5 AMPs. • Backup Battery: • 6 VDC Lead Acid, @ 8 AH. (Two Batteries Required). • Fuses: • AC input fuse: 2 AMP, Slow Blow, Full Size Automotive Type. • Battery fuse: 8 AMP, Slow Blow, Full Size Automotive Type. • Alarm Outputs: • Form A for AC Power Fail. • Form A for Enclosure Cover Tamper.
Power Supply Tech Tips • AC must be wired by Qualified Electrician. • Earth Ground to Terminal 12. • Use Solid Core cable, AWG #10 or better. • Less than 50 ft to ground source is ideal. • Use 6” radius bends on the cable. No sharp 90º corners. • Use mechanical ground clamp to attach wire to ground source. • Use CWP, UFER ground, or some other verified and approved ground source. No Gas or Fire Sprinkler Pipe. • Create a monolithic shield for the signal ground. • Ground shielded cable on one end only. Tie down the shield to terminal 12. • The -TXR and +TXR terminals are not used on additional power supplies within the same SCU branch. Only the shield and a common negative is connected between power supplies to establish the bonded signal ground.
Power Supply Tech Tips • The Power Supply can only be loaded to a maximum of 80% of its current rating. • Maximum rating is 5 AMPs or 5000 mA. Eighty percent loaded is 4 AMPs or 4000 mA. • Replace fuses with like rated fuses. • Replace lead acid batteries every 3-5 years. • The Unican part number for the power supply is: 120 VAC, 60 Hz PS1-100212-001. 240 VAC, 50 Hz PS1-100213-001. • Power Supply part number includes batteries and a locking enclosure.
