Orderable3.8 A 24 V NEC Class 2 Power Supply Kit
Overview
The 44157 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 44157 with the -UL option, as well as part number SP27623, are used in UL508A-certified enclosures assembled at Campbell Scientific.
Technical Description
The 44157 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 44157 is purchased with a prewired or UL enclosure, the 44157 will be assembled at no additional cost. If using it with a standard enclosure, Campbell Scientific will assemble it for an additional fee.
