A, 1, electrical characteristics (1) the basic features 12 to 24 v DC input voltage (2) working current 5 a (MAX) (3) standby current 25 ma (4) or less load characteristic constant voltage (5) the load power 60 w 2 or less, general parameters (1) touch the induction distance is 6 mm or less (glass) of medium (2) glass, plastic, touch the induction medium (must be an insulator) (3) the ambient temperature (Ta) and 40 ℃ ~ + 45 ℃ (4) the highest surface temperature (Tc) 70 ℃ (5) the relative humidity of 25% to 90% RH Description of functions: This product has time display and temperature display functions. If the temperature display function is not needed, then the temperature probe (NTC) can be disconnected (the temperature probe interface is suspended). Time display 5s, temperature display 2S, the two display alternate; When the temperature probe interface hung up only show the time adjustment: long press the button 3 s to enter time adjusting state, \"when a flashing\" clock module, the short press button \"when\" a numerical increment of clock module, every short according to the numerical plus 1, also can be long press to make it fast adjustment, \"when\" is numerical control loop, when numerical increase to 23 will jump to 00 start; If you do not operate for 5 seconds after the \"hour\" adjustment, you will enter the \"minute\" adjustment state. The adjustment operation is the same as that of \"hour\". After \"minute\" adjustment is completed, if you do not operate for 5 seconds, you will enter the state of saving time and leave the state of adjusting time. The display value will stop flashing. With the touch switch, the process of adjusting time is the same as with the mechanical button, but it can only be adjusted when the touch switch is turned off. (The matched touch switch is equipped with lamp control function, please refer to the touch switch related manual for specific information)
