The Honeywell 14507287-002 is a power module that supplies regulated 24 VAC power to Excel 80B/B2, 100B/B2, 500, and 600 Controllers, plus the Q7645A Excel Link. It accepts 120 VAC, 50/60 Hz input and delivers dual 24 VAC outputs—one for controller power and one for accessories at 4 AMP MAX. The module integrates line bypass capacitors for noise filtering and Metal Oxide Varistors (MOVs) for surge suppression. Each output has independent fusing; separate ON/OFF switches control each transformer. A 10 AMP MAX convenience outlet provides unfiltered, unswitched auxiliary power. Construction uses heavy-gauge metal chassis with minimal mounting hardware. The unit complies with UL864, UL916, NFPA92A, and FCC Class A computing device limits. It is designed to help controllers pass Honeywell transient and surge tests. Terminal “G” must connect to earth ground for proper operation.
