relay dc to ac

1 Answer. Sorted by: 5. When the relay opens it will draw an arc. With AC power the current drops to zero 100 or 120 times per second (depending on whether you have 50Hz or 60Hz power), and this will allow the arc to extinguish.

Yes, as long as you respect the ratings of the relays you use. You'll need to make sure that you find a relay with a 5VDC coil voltage, and a high enough rating for the contact voltage and current. For example, this relay would be appropriate for a load that draws up to 10 amps of current for a resistive load, and up to 5A of current for a ...

Solid state relays can be designed to switch both AC or DC currents by using an SCR, TRIAC, or switching transistor output instead of the usual mechanical normally-open (NO) contacts.

AC Solid State Relays : The switching component of an AC Solid State Relay is a Thyristor, also named SCR (for silicon controlled rectifier) or triacs. Thyristors are control gate diodes. They are conductors in one direction only. DC Solid State Relays : For DC-to-DC Solid State Relays transistors are used as switching elements.

Often used to regulate the speed of AC fans or keep a heater at a set temperature, these relays connect directly to sensors to calculate and adjust output power. This allows you to use an analog input without converting it to a digital signal to control output power.

Would it be possible to also use the same relay for say a 25VDC, and less than 1A load? From here, relay power ratings - AC vs DC , it seems to imply that that due to arcing, an AC relay would be able to support switching DC as long as the DC voltage is about 1/10 of the AC rating.
