![CPM 16-30](http://docs.poweroptimal.com/uploads/images/gallery/2026-06/embedded-image-xo636co8.jpeg)

***The PowerGuard CPM16-30 is a 16-channel demand regulator with 30 Amp switching capacity per channel designed to work with the PowerGuard CPM-3PC or CPM-3PC Mk2 controllers. The unit was developed primarily to reduce costs on demand sensitive electricity bills but can also be installed for customers who do not have enough power.***

*This certified unit is designed and manufactured in South Africa.*

*SPECIFICATIONS*

***INPUT***

Shed requests are received via a polarity insensitive low voltage short circuit proof signal generated by the PowerGuard CPM-3PC or CPM-3PC Mk 2.

***CONTROL & PROGRAMMING***

Various algorithms can be selected to optimise the control of air conditioners, geysers and boiler elements thereby making intervention seamless in most installations.

Progressive load restoration assists with ‘’cold pick up’’ situations following supply interruptions. All control criteria are switch programmable in order to avoid the need for laptops or specialised software.

***DISPLAY***

LEDs indicate shed status as well as processor heartbeat, control signal presence, over-voltage and supply activity.

***SPECIFICATIONS***
