Solid State Relays  from Prime Controls Co.   MDI

MDI Incorporated is a well-known manufacturer of mercury displacement relays, which are great for heater contactors. However, mercury contactors have been banned in California (even as replacements) and in several other states, so MDI has designed a solid-state relay package to replace them directly. They also offer solid state relays with integrated heatsinks. The most common configurations are in stock at Prime Controls Co. Call us for more information, for quotes or to order.
