SCMXPRT-001/D, SCMXPRE-001/D
Power Supplies
Description
The SCMXPRT-001/D and SCMXPRE-001/D encapsulated power supplies are
available in 120VAC or 220VAC input voltage ranges and provide 5VDC outputs
suitable for all 8B modules. They are designed to mount on the SCMXRK-002
metal rack (see Figure 13) or DIN rail EN 50022-35x7.5 (D versions). The
supplies are UL-recognized. Their compact size and low weight are ideal for
high-density applications (see Figure 8).
