I have a 100A DC/AC zero-switching SSR rated for 3-32 VDC input and 24-480 VAC output. My load is a 150W, 24V lightbulb, the positive wire of which is connected to Terminal 1 of the SSR, and negative wire connected to the black neutral wire of a laptop charging cable. The white live wire of the cable is connected to Terminal 2 of the SSR. Input voltage is being provided by two Arduino Uno output pins set to High. I’ve measured the voltage difference across input Terminals 3 & 4 of the SSR to be ~4.65 VDC, which is sufficient to turn the SSR LED on. The problem is my lightbulb isn’t lighting up. A continuity test across output Terminals 1 & 2 with my multimeter shows it’s an open circuit. Any ideas or insights would be much appreciated!
See below for code and picture of setup.
const int plusPin = 2;
const int minusPin = 4;
void setup() {
// put your setup code here, to run once:
pinMode(plusPin, OUTPUT);
pinMode(minusPin, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite(plusPin, HIGH);
digitalWrite(minusPin, LOW);
delay(1000);
}
