Overview

The XM3.1-HP provides Outputs 1 & 2 for powering broadband devices and one auxiliary output for powering ancillary devices in the enclosure. The output voltage for Output 1 and 2 are dependent on the model of the power supply and the location of the Vout Selection Tap. The output voltage of Auxiliary Output 1 is dependent on the model. See page 5 for model numbers and their corresponding output voltages. The XM3.1-HP is composed of the following embedded modules:
Transformer Module — provides a critical load with current-limited regulated AC power that is free of spikes, surges, sags and noise.
Power Processing Module (PPM) — contains circuits for the Inverter, Sensing, Relays and Input/Output power. Power Control Module (PCM) — controls the core power supply functions such as Line Mode (AC Input), Inverter, Battery Charger, Data Storage and AC Output.
Element Monitoring Module (EMM) — is the interface between the Power Control Module and the Cable Modem Module (CMM). The EMM provides the necessary data storage and performs advanced functions such as logging power supply events, utility events, and battery health analysis. Additionally, the EMM provides the interface for the local web page and logic for the ancillary equipment such as tamper switches. NOTE: Should the EMM be removed, the Smart Display will be disabled.
Cable Modem Module (CMM) — interfaces with the EMM to provide the necessary communication over the DOCSIS® and Ethernet networks. The CMM enables the local Ethernet port for local web server access. The CMM may be removed from the power supply along with the EMM. NOTE: Smart Display functionality will cease until the EMM is installed. Fig. 1-1, Main Features of the XM3.1-HP Series Power Supply
