That being said, usually the thing that will reduce a relay’s power consumption the most is to simply use a latching relay. Generic. Our relay here has 5V trigger voltage, but you can also find relays of values 3V, 6V and even 12V so select one based on the available voltage in your project. At this point the relay actuates. If the ESP32 takes 200 mA, with a switch mode supply that should drop to 100 mA. Note that the voltage required to turn a relay on (pick-up voltage) is greater than that required to keep it on (dropout voltage). If you want to externally power the relay itself then make sure to connect the +5 to the Vcc on the relay board and the -lead to the GND on the relay board. With 1.2V across the coil its impedance is about 128 ohms as also determined during characterization. From our characterization exercise we know that we want the holding current through the coil to be around 9 to 10 ma and the voltage across the coil to be about 1.2V. Find the best pricing for Panasonic S3EB-5V by comparing bulk discounts from 6 distributors. I used the UNO 5V and GND pins to power the relay module and then measure the open circuit IN voltage.

The relay actuates and disengages immediately as 5V is applied and removed and latches on when 5V is applied. A picture of the schematic is attached. With a value of 390 ohms for R1 the holding current through the relay is about 9.5 ma as opposed to the measured pick up current of 36.6 ma with the full 5V applied to the relay. The way the circuit works is that when 5V is applied, C1 is momentarily a short circuit and current flows freely through C1 and R3 into the base of Q1. Using the equation P = IV, therefore I = P/V. 5 (1) +1. For a better experience, please enable JavaScript in your browser before proceeding. Future Electronics. Insensitive to positioning. Arrives before Christmas. It automatically turns on and off street lights. While relays are very useful for switching things on and off, for situations where power consumption is to be kept to a minimum, the power used by the relay itself can be a problem – for example where a small LED light is to be switched, the power taken by the relay could be more than the power taken by the light.

Obviously depending on the relay type some component values might have to be modified, but the method described should work for most DC relays. An alternative to relays for switching low to moderate DC voltages is FETs. Not effected by magnetic fields. Power consumed by the relay coil equals V²/R COIL. High for on, low for off. Quieter operation. Power Consumption: About 2VA. You must log in or register to reply here. If you want to know the relay power consumption you need to read it´s datasheet. a solution is to use a polarized latching (bistable) relay. The advantage of using a 5V relay in this project is that the power supply for the relay can be directly given from the Arduino UNO board itself.
