Can I use a larger HVAC Hard Start kit than is recommended?
The starting capacitor is the largest difference in the various 5-2-1 devices. You don''t want too large of a starting capacitor. You need to use the correct one for your application. FYI: Multiply the load amps by 2,650. Divide this number by the supply voltage. The resulting number is the capacity of the capacitor you need in microfarads (µF).
Energy saving capacitor
Suppose 100 people buy such a device and install it in their home. Since everyone''s power use fluctuates month by month, even if the energy saving capacitor does no good at all, some people are bound to see a drop in power use from one month to the next, while others will see an increase.
Transformer-based AC/DC converters | Power Supplies | Adafruit …
Ripple voltage = Current draw / ( (Ripple frequency) * (Capacitor size) ) or written another way. Capacitor size = Current draw / ( (Ripple frequency) * (Ripple Voltage) ) For a half wave rectifier (single diode) the frequency is 60 Hz (or 50 Hz in europe). The current draw is how much current your project is going to need, maximum.
