About Us and Our SSR Manufacturing Partner:

National Platic Heaters' solid state relay partner is an electronics design and manufacturing company, therefore, we are able to carry a full a line of standard solid state relays and SCR power controllers.  Our standard line has power handling capability’s from 0-200A in single, 2 pole and 3 phase.  We can also custom design SCR power controllers to meet some of our customers most challenging design needs.  We have Microcontroller based phase angle and time proportioned power control electronics.  Our engineers will be more than happy to assist you on custom software / hardware designs that will handle your power needs exactly to your specs and we never charge upfront engineering fees for this service.

Heat management is one of the most important components to a proper design of an SCR power controller, contactor or relay assembly and in this area National Plastic Heater provides solutions to maintenace supervisors and managers worldwide. We have been specializing in this industry since the 1990’s and have the benefit of many years of skilled engineering in our designs.  We have many custom engineered heat sinks for even the most challenging situation.  Our partners test lab can run tests up to the full power handling of our products while monitoring and recording operational and environmental data to ensure an application will work in the field. 

Our solid state relay partners engineering staff continues to research new and developing technologies to ensure that our products are getting the most up to date technology possible.  Due to our large inventory of components and precise management of product flow to customers requirements, we are not a “just in time” or “almost in time” manufacturing company.   We strive to be a “always on time” company that assures our customers that ALL of our standard assemblies are in stock and ready to ship the same day the order is received.

While being large enough to serve some of the worlds biggest companies with their solid state relay (SSR) and power control needs, National Plastic Heater is still a very approachable company.  If you have a questions you can speak directly to us or with our manufatures' engineers.  One of our two manufactures' engineers is almost always available at the plant and will be more than happy to chat with you about the many benefits of using NPH on your next project whether big or small.  We daily ship single item orders with no minimums as well as shipping out thousands of units to some of our larger clients. 

Please do not hesitate to call in to speak with our staff to ensure that you have chosen the correct part or if you have any questions at all regarding your solid state relay, transducers, power monitotring and power controller needs.
