Overview
The 28370 is a 24 Vdc power-supply kit that includes a 24 Vdc, 3.8 A power supply, along with hardware for mounting and wiring inside standard Campbell Scientific enclosures. The 28370 with the -UL option, as well as part number 27623, are used in UL508A-certified enclosures assembled at Campbell Scientific.

Detailed Description
The 28370 kit includes a DIN rail bracket, DIN rail connectors, breakers, and the Phoenix Power Supply. This kit does not contain a battery and therefore requires a PS150, CH150, PS200, CH200 or possibly a larger battery if using it with our data loggers.
The raw kit comes unassembled, but its user manual provides assembly information. If the 28370 is purchased with a prewired or UL enclosure, the 28370 will be assembled at no additional cost. If using it with a standard enclosure, Campbell Scientific will assemble it for an additional fee.
