Site power infrastructure

The site receives a 208V, 400A 3-phase service, divided into 200A for the office building and 200A for the radar systems on-site. A variety of field power outlets are available, including:

Current	Type	Connector	Backup
200A	3-phase, 208V	Hard-wired	Yes
100A	1-phase, 208V	Meltric DS100 receptacle	Yes
30A	3-phase, 208V	IEC60309 pin and sleeve	Yes
30A	3-phase, 208V	L15-30R	Yes (bldg ckt)
60A	Split-phase, 208V	IEC60309 pin and sleeve	No
30A	Single-phase, 208V	L6-30R	No

The site has a 100 kVA diesel backup power generator designed to support the power needs of the site during multi-day power outages. An additional 25 kVA propane-fired generator supports the inflatable CSU-CHILL radome structure in the event of a main generator outage.

Network Connectivity

The CSU-CHILL site provides network connectivity (25 Mbit) through a wireless link. The link terminates at the University of Northern Colorado, which provides high-bandwidth connectivity via optic fiber to the CSU main campus.

Failover network connectivity is through a Starlink antenna.
