STC-8080A+ is a universal temperature controller with single sensor,specify all the functions as refrigerating,defrosting,alarming when temperature exceeds setting limit.Compressor delay protection time is solidified as 3 minutes,Controller start up and close according to the solidified proportional time when sensor error,which can be applied to the industries such as cold storage,refrigerator car,etc.Main functions: To measure,display and control temperature. Defrosting cycle and defrosting time is adjustable. Alarm when temperature exceeds setting temperature limit value. Compressor start up delay protection. Compressor work as scheduled time when sensor error.Model: STC-8080A+supply voltage: 220VAC+10%/-15%,50/60Hzconsumption: less than 3WTemperature measuring range :-50C to 99 CThe temperature range is :-40C to 50 CMeasurement accuracy: 1 CAccuracy: +/- 1 C (-40 to 50 C), +/- 2C (Other)Relay capacity of compressor:10A/220VAC,Relay capacity of defroster:10A/220VACSensor error relay time :1 minuteSensor type :NTC sensorFront panel safe level :IP64Operating temperature:0C - +60CRelative humidity :20%-85%( No condensate )Storage temperature:-30C - 75CColour: blackMaterial: plasticPackage Contents:1 * STC-8080A+ Digital Temperature ControllerOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
