CR Magnetics Focus on Service and Technology

Professional Engineers

CR Magnetics staff includes engineering and technical professionals who bring a century’s worth of experience in the electrical monitoring and power measurement industry. This experience provides our customers with solutions in solving the most difficult application challenge.

Our fully NIST traceable lab consists of six testing stations, each with laboratory grade closed loop controlled power system references that are used to provide exacting baseline inputs for proper calibration of all our products. These stations can create the identical situation faced in the field by our customers, including any voltage, current, or frequency level. The shape and form of these signals can also be adjusted to provide data on how our products react in these situations. CR Magnetics also maintains the proper power meter testing equipment which is designed to meet the parallellogram method of the ANSI grade meters, as well as an engineering based test system to verify absolute phase angle shifts with initial inductance measurement of our sensing transformers. These stations are specifically designed to provide the correct specifications for our products when applied in unique or common applications.


All CR Magnetics parts meet the lead-free and other dangerous chemical requirements of RoHS. Our most popular products carry CE, UL, and CSA certifications. Our facilities also include the necessary equipment including high-pot testing, environmental testing, and load testing to be able to provide our customers the information and source they need when exploring custom solutions that require agency approvals. Our experience in working with certified bodies make implementing new and exciting monitoring schemes much easier and quicker.

CR Magnetics staff includes quality monitoring and assurance personnel. These personnel have no other function than to make sure our products are maintained with the highest quality level possible. All quality issues are tabulated from customers, employees, and suppliers. Documentation maintained includes customer complaints, corrective actions, and fully traceable materials from supplier through customer. Statistical process control is utilized in the winding, potting, and calibration areas, controlled by documented setups, and re-verified on a regular basis. All procedures are maintained and referenced in an industry standard quality manual.
