The Warner Electric TC-324B is a single-channel automatic heater controller for precise temperature regulation in sensitive experimental systems. It operates in both automatic and manual modes with dual thermistor capability for simultaneous control and monitoring, delivering up to 18 W of low-noise heating power at 12 V DC and 1.5 A maximum output. The controller integrates highly filtered DC supplies and slow-ramped analog switching circuitry to minimize noise, making it well-suited for electrophysiology and other demanding applications.
