Chromalox MMAX1P-10160 SCR Power Control

The Chromalox MMAX1P-10160 SCR Power Control from Thermal Devices, an authorized Chromalox distributor. The Chromalox Model MiniMax 1 Single Phase Solid State SCR Power Controller is a highly versatile power pak with optional plugin proportional Firing and Shorted SCR Detection Boards. Firing modes include: “ON/OFF Power Control” (Contactor) and “Proportional Power Control” (Zero Voltage Switching, DOT fire). Chromalox’s exclusive DOT (Demand Oriented Transfer) firing switches the fewest number of cycles to provide the most precise zero crossover control. At 50% output the unit’s output alternates between one electrical cycle on and one cycle off. At 51% the output continues with one cycle on / one cycle off and gradually integrates one extra “on” cycle for the additional one percent. With the exception of phase angle firing, DOT firing is the most precise method of SCR control. DOT firing is preferred in many applications because phase angle firing creates unwanted RFI. DOT is excellent for applications where consistent heater/process temperature control is critical.
