For years, Kele has provided dependable, quality 24 VDC power supplies like the DCP-1.5-W, DCPA-1.2, DCP-250, PW2, and the SLS Series. All of these DC power supplies are “linear” power supplies. Another type of DC power supply gaining popularity with building automation and temperature control contractors is called a “switch-mode” power supply (PS6R Series). While both […]

Does Your Building Own its Energy Destiny?
Those of you who have read some of my past blogs have probably gathered by now that I’m fascinated by the intersection of building automation, energy and the coming Internet of Things (IoT) revolution. What captivates me most about this collision of previously tangentially related and/or non-existent industries? The monumental shift of perception I believe […]
Read PostBelimo Zip Economizer – Time Saver!
The Belimo Zip Economizer is really a cool product that captured my attention. If you are or were in the field like I was, I’m sure you’ve struggled just as I did with the “Black Box” style of economizer modules. They could be difficult to commission at start-up if the OSA (outside air) was not […]
Read PostOur Coming Transactive Energy Economy
While scanning through the building automation and energy industry news recently I came across a term I hadn’t heard before. The term, Transactive Energy, piqued my interest and upon reading further I found this article from The Energy Collective website to be excellent in succinctly describing where I believe our electricity market is headed; and the implications […]
Read PostWho’s afraid of the IoT (Internet of Things)?
A few weeks back I blogged about the IoT (Internet of Things) and its historical ties to and implications for the building automation industry. Given factors I discussed there and in another blog where I talked about the democratization of building controls, the intelligence of building automation systems is expected to grow exponentially in the coming years, creating […]
Read PostSpring Return Fail Safe Electric Motors
Consideration must be taken when designing a control system as to what happens when controllers fail or if there is a loss of power. This is referred to as fail-safe or spring return. Devices, like valves and dampers, can be made to fail in a position that provides a minimum amount of comfort control or, […]
Read PostThe Democratization of Building Controls
Yesterday I read an interesting article that focused on a cleantech startup’s recent venture capital funding success story. The company, Enlighted, provides smart lighting sensors and software that reduce a building’s power consumption. This concept is nothing novel to the building automation industry, however, according to the article, Enlighted has taken a bit of a different […]
Read PostWireless is Becoming More Visible
New technology is always in some sense a little frightening and permeated with uncertainty, whether real or perceived. The very nature of it makes us cautious and reluctant to accept it. We then in turn, take smaller steps and fewer risks. While sometimes these new technologies give us cause to pause, it also offers us […]
Read PostHoneywell T775 Controller
I started at Kele about 19 years ago. Over the years I’ve been fortunate to learn a good bit about controls from many very talented folks – mentors, fellow employees, industry experts, and customers. It is easy to have favorites in my line of work. Being in tech support over an extended period of time, […]
Read PostBuilding Automation and the Internet of Things (IOT)
A topic getting a lot of press these days (at least in the publications and on the websites I frequent) is the Internet of Things (IOT). If this phrase is unfamiliar to you now, it probably won’t be for long. We are headed toward a world of greater and greater connectivity and IOT will increasingly […]
