Overview

The 28371 is a 24 V power-supply kit that includes a 24 Vdc, 10 A power supply, along with hardware for mounting and wiring inside standard Campbell Scientific enclosures.


Detailed Description

The 28371 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 PS100, CH100, PS200, CH200 or possibly a larger battery if using it with our dataloggers.

The raw kit comes unassembled, but its user manual provides assembly information. If the 28371 is purchased with a prewired or UL enclosure, the 28371 will be assembled at no additional cost. If using it with a standard enclosure, Campbell Scientific will assemble it for an additional fee.
