Power Supply
The MS27102A Remote Spectrum Monitor comes with an indoor AC/DC power converter with a pre-assembled power cable and gland. This is to be used only for indoor applications. For outdoor usage, a DC power supply must be supplied by the user and must meet the following criteria:
• Voltage rating: 11 VDC to 24 VDC (supplied at instrument connector)
• Power dissipation: 11 W
• Environmental ratings: IP67 rating recommended or otherwise suitable outdoor supply, including supply cabling
• Power cabling: appropriate weather resistant cabling with adequately sized conductors for the length of run and power demand. The provided connector has screw terminals and will work for wire sizes from 14 AWG to 18 AWG with an outside cable diameter of 5.5 mm to 8.0 mm (0.22 to 0.31 in).
