Detailed Description
The 28372 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 28372 is purchased with a prewired or UL enclosure, the 28372 will be assembled at no additional cost. If using it with a standard enclosure, Campbell Scientific will assemble it for an additional fee.
