How does the DH-65 work?
The Southern Pride DH-65 Smoker is a purely electrical unit that requires a 208 or 220 volt, single-phase 30-amp circuit. The smoker consists of a 208 or 240-volt, 4500-watt main heater, a 110-volt 300-watt smoke element, a 110-volt 750-watt steam element and a 110-volt convection fan motor. Cooking times and temperature are controlled by a digital control system.
Digital control system
The digital control system consists of a digital controller, a 110 to 24-volt step-down transformer, a 40A, a 25A and two 10A solid state relays. To avoid overheating, a 340-degree high temperature thermostat and contactor is used in the circuit between the 40A solid state relay and the heating element. 110-volt power of the black and white lines of the terminal block is sent to the transformer, to the fan-type semiconductor relay, the flue element semiconductor relay and the semiconductor relay of the steam element. 208/240 volts from the black wire of the terminal block are sent to the contactor and the red wine is connected directly to the other cable of the main heater. If selected, the “cooking” menu and the START pad is pressed, the digital controller sends 5 volts DC to the convection fan, heater, steam element and the semiconductor relay of the smoke element. In addition, 110 volts are sent from terminal # 1 of the fan relay via the temperature limiter to the terminal of the contactor coil. If the temperature of the smoker exceeds the maximum limit of approximately 340 degrees, the Hi-limit thermostat will open, whereby the 110 volts will be switched off in the contactor coil and the heating element current interrupted until the smoke cools.
