How to connect LED light fixture and Peltier cooler in same DC power supply without reducing their capcity? Answered
I have a atx power supply which i have converted to 12 V DC power source, current rated as 22 amps.
I have connected a LED light appliance(90W) and a peltier cooler(62.2 W, Umax =15.4 v, Imax = 7 amp,1.7 Ohm resistance ) in parallel connection. But when i attached both of them to the PSU , my LED lights dim. What is the reason for this ??
I have tried with other combination that is peltier cooler and CPU cooler fan and find that the fan is not operating in same rpm when it runs as a sigle device with PSU. Is Peltier cooler make the circuit short??
