- 8 - LINQ8ACM(CB)
Tango1B - PoE Driven Power Supply with Lithium Battery Backup
Overview:
Altronix Tango1B Voltage Regulator converts an IEEE802.3bt PoE input into a regulated 24VDC and/or 12VDC
output up to 65W. It eliminates the need for a high voltage power supply inside of an enclosure. The Tango 8-pin
connector allows for stacking with LINQ8ACM(CB), saving valuable enclosure space. Tango1B is designed to
support a single 12V LiFePO
4
(Lithium Iron Phosphate) battery for high storage and charge/discharge cycle
life reliability. Refer to Tango1B Installation Guide Rev. TANGO-071119.
Specifications:
Connecting LINQ8ACM(CB) to Tango1B:
1. Fasten male/female spacers (provided) to pems that match the hole pattern for Tango1B in the desired
location/enclosure (Fig. 4, pg. 8).
2. Plug-in male 8-pin connector to female 8-pin receptacle on Tango1B board.
3. Fasten female/female spacers. Use metal spacers over mounting holes with star pattern (Fig. 4a, pg. 8).
4. Align 8-pin male connector with female receptacle of LINQ8ACM(CB), then mount.
5. Connect 24VDC power supply to terminal marked [+ PWR1 –] of LINQ8ACM(CB).
Thus Input 1 of LINQ8ACM(CB) is 24VDC from power supply and Input 2 is determined by
Tango1B’s settings (12VDC or 12VDC).
6. Complete steps 4-10 (pgs. 3-4).
