The aim of the device is to control the temparature inside small battery-powered inclubator. The main temperature stabilization is provided via PID (proportional-intefral-differential) control loop function. The use of PID instead of simple relay control provides high level of stability of temerature control.
Input: AC 100-240V, Output: DC 19v±3% 100W 5.3A, Efficiency: Better than 90%, PCB overall dimensions: 161 x 60,65mm ± 0.15mm. Putting power supply in specified dimensions was tough job, but we did it successfully.
