Power Conditioning Required for Terminal-Fueling Depot Installations
Two separate electrical components are installed in EMR
power supply (UPS) (recommended) and a +12 Vdc power supply (required). Veeder-Root recommendations for
this equipment are discussed below.
1. UPS (Uninterrupted Power Supply) - Optional
Veeder-Root recommends the Tripp Lite UPS model BC PERS450 (or equivalent) for up to 15 minutes of
power backup to the +12 Vdc power supply. For pricing or additional information, you can phone Tripp Lite
customer support at (312) 755-5401; or write them at Tripp Lite Worldwide, 500 N. Orleans, Chicago, IL
60610; or visit their website at www.tripplite.com
2. Power supply - UL approved, 120 watts
Veeder-Root recommends the Digi-Key Model 62-1050-ND 12 Vdc, 13 ampere power supply, or Model 62-
1051-ND 24 Vdc, 6.5 ampere power supply. (See Figure 33 for connection wiring diagram which is identical
for either the 12 or 24 Vdc model.) To order, contact Digi-key at (800) 344-4539, or visit their website at
