Apply Power to the X2-SDL


The X2-SDL has flexible power input choices that provide several options in terms of type and number of power sources.

Basic Requirements

  •  5-24 VDC [+/-10%] (Reverse polarity protected)
  • Current Draw (Typical @ 12VDC): Low power sleep: 350uA; Logger Active: 35mA; Wi-Fi Transmitting: 43mA; Cellular Transmitting: 300mA
  • Peak Current: 500mA @ 12V for 1 second

 

Input Channels

The X2-SDL is equipped with two separate power input channels. The X2-SDL pulls power from the highest priority channel that has a voltage within the specified range. If one of the sources falls outside the range, the next highest priority channel will automatically take over without an interruption in supply.

From highest to lowest priority, the channel order is as follows.

  • Primary
  • Backup

This multi-input design allows users to connect redundant power sources in order to mitigate the likelihood of system power loss.

 

Typical Application

Frequently, X2-SDL systems are run off of (16) internal D-Cell Alkaline batteries. The following article describes the process for installing these batteries properly before deployment.

Connector Wiring

Power may be applied to the X2-SDL via the UW-6 receptacle port by a UW-USB-485P for connection to a PC, or from a customized solar power kit. Most applications; however, rely on the internal D-Cell Alkaline batteries during deployment.
