To the Powerline SubMeter product family PowerHouse PL belong digital AC meters for building automation and energy management. The SubMeter is used to provide basic power metering and ON/OFF control of a load by a remote control of a relay (switch). A very important objective for this product family is to provide an interoperable device definition that makes it possible for a system integration company to deliver a system where sub meter nodes (devices) from different manufacturers can be integrated with a minimum amount of effort. In addition to the detection of the electrical activity W [kWh], the following physical values are also detected: electrical power (active, reactive and apparent power), rms values of current and voltage, and the PF and the mains frequency with the accuracy class A, (2%) according to DIN EN 50470 -1 and -3. The measured values are transferred to a LON Powerline network or to a central control using standard network variables (SNVTs) in accordance with the LONMARK standard. The SubMeter Powerhouse PL based on the LONMARK functional profile “Single-Phase SubMeter” Type #2161. Depending on the housing type, the SubMeters have a relay output of 10A or 16A @ 250V AC. The Powerline SubMeter is available in three housing variations: • DIN rail housing • flush-mounted socket • plug case
The number of applications for LonMark certification is growing rapidly. To make sure your products are on-track for certification, design conformance into them by following the LonMark Interoperability Guidelines v3.4.
The Proficiency Testing Program for Qualified Open Systems Installers, Professionals and Integrators provides a worldwide standard of proficiency for individuals that install, integrate and maintain systems utilizing LonMark certified products.
