APC S20 - v 7.0.0

Extra Vegetables' Control4 driver for the APC (American Power Conversion) range of UPS enables a Control4 system both to control the operation of the UPS and to receive feedback from it.

This is an invaluable tool on any customer's site as it allows the Control4 system to monitor the health of the power at the property and to react accordingly. Should a problem occur with the power the dealer can be informed of the problem and, if an IP power switch, is installed it is possible to provide a controlled shut down and power save sequence for the property. Dealers can also remotely interrogate the UPS to analyze the current power conditions through Remote Director.

This is the driver for the APC S20 AV Power Conditioner with battery backup. This driver provides all of the functions of the SmartUPS driver together with the ability to switch any of the four outlet banks on the rear of the UPS. 

Also available as part of the Monitoring Suite with the network monitoring, rebooting and ping drivers.
