Hi i have a project that on occasions needs the peltier to ramp down and then ramp up (not instantly) using pwm The time factor for the ramping period is not critical over a period of 10 minutes is no problem. Has anybody an idea of a period i could use to prevent temperature change shock to the peltier, for example would dropping 1 duty cycle every 1 minute be detrimental to the peltier.
