S20 Power Conditioner with Battery Backup features network manageability and temperature/humidity monitoring, as well as APC’s legendary battery backup protection.  The S20 gives installers the ability to remotely reboot hung equipment, saving customers a costly and intrusive service call. For example, if the S20 reaches a low battery condition, the network will respond to this signal by putting the projector into standby allowing the fans time to cool down the bulbs before the unit’s batteries fully deplete.
