I have a pineapple conure who loves to go for car rides2 - 3 times a week I will take her with me to pick the kids up from school or sports practiceShe doesn't get out of the car most times and spends no more than a minute actually outsideAs the seasons are changing and temperatures are dropping, I am wondering how cold is to cold for her to go on car rides.
Hopefully, either you have the bird on a leash or in a cage!!!!! I have taken my parrot out in the middle of winter but he has been wrapped in a warm blanket with only his head out and only for a few minutes at a timeWhen your bird starts to sneeze and has a snotty nose and is having trouble breathing and can't eat or is on the floor of the cage with his feathers all ruffled, you'll know that he has been out in the cold too long.
Please review your calculation of power dissipationThe coil of relay (200 ohm) consumes 0.06 AThe calculated resistor is (220-12)/0.06 ohm 3467 ohmPower dissipation of the resistor 2080.06 12.12 wattWow, it is a big size resistor that your space won't handle due to its size and heat dissipationI suggest you select smaller relay of 2500 ohm(consumes 5 mA) that power dissipation is about 1 watt.And then you can use 47K resistor in series with a small diodePlease provide an electrolyte capacitor to stabilize the voltageProvides a zener diode of 12 volt will be better.
use a step down transforemer of 220 to 12 volt then u can use any kind of 12 volt relay to it very simple and safe
You could use a large value capacitor, and that will mean that the power dissipation problem is reducedYou need to put a bridge in series with a 12V zener across the output of bridgeThe current being 60mA, and I guess 50mA might suffice, you may have to use about 0.7uF as series capacitorthis has to be rated at 400VSo I guess that will not substantially smallerbetter use a diode in series to reduce the voltage substantially, and use a resistor of 1.4k or soWattage, 88V60mAIf current required for operation of relay is say 80%, the resistor can be 1.8k, and wattage 90.05 4.5 wattsA 5 watt resistor will do(Yes: do not forget to use a diode in series to get halfwave rectified 230V.
This Site Might Help YouRE: How can I run a 12 Volt Relay in 220 Volts AC mains? I don't want to use or have more space for a transformer and a diode bridge inside the machine I'm makingThe voltage is 220V ACThe relay I shall use is of 12volts 200ohmsCan I use a resistor of big value (like 82K from power dissipation calculations) and a diode in series with the.
