Sample which this time sends about IPV development product technical order , is the improvement opinion which proposed recently according to your firm carries on the design to complete. the primary coverage is as follows: one. Display panel: the 1. display panel increases the thin film switch panel's design and the processing; On the kneading board increases the AES work indicating lamp; 2. Revision monolithic integrated circuit functional software. two. Control panel: the control panel output power tube increases the radiator fin to strengthen the radiation ability; Four needle plugs change two two needle's plugs; three. Power panel the 1. power panel increases the AC first function, changes the original 24V power supply to change now the 12.5V power supply. sends the new model function realizes. Needs to explain has the following content: 1, the Celsius Fahrenheit transformation change (ON/OEF) and (-) simultaneously press down realize, originally the expensive department request uses (-) and (+) two simultaneously presses down realizes, the software design cannot complete. 2, the thin film switch panel and the demonstration PCB board connection structural design is improper, already revised the design, but the PCB board not yet processes. other, debugs us after the experiment to think that the power supply is 24V is quite good, after changing the 12.5V power supply, the power panel cost increases. the display panel power light demonstrated that uses red green and LED is good, not only whether there is demonstrates the power source, also simultaneously demonstrates the refrigeration system hot active status. has He Xin's opinion and suggestion please as soon as possible comprehensive statement regarding this sample expensive department, strive for next time disposable to complete.
