## Description

HELLA H41773001 Solid State Ceramic 32 Amp SPST Mini Relay

Review: Great Product! - I used two of these to wire-up a high amperage, PWM (pulse width modulated) engine cooling fan, and I am very pleased with there performance. Amperage rating for this relay is 22 amps, at maximum operating temperature, according to Hella's web site. Use multiple relays, wired in parallel, to match your equipment's maximum operating amperage + 15%. My fan pulls 35 amps, so I used two relays for a total of 44 amps. (35 amps + 15% = 40.25 amps) This relay will fit in a standard socket, and the pins are numbered the same as a standard relay, but the wiring is different. 30 = Battery + (High Amperage) 87 = Load (High Amperage) 85 = Ground (Low Amperage) 86 = Switched Ground (Low Amperage)
Review: Returned by mistake - Bought these relays, did not wire my ECU correctly and thought the issue was these relays, the issue was caused by not adding a power to Pin A26 on my Haltech Elite ECU, these relays would have worked great and would have been reliable, unfortunately I returned them.

## Questions & Answers

**Q: Will this behave the same as a mechanical spst relay? i'm basically looking for a spst relay that doesn't make any clicking sound.**
A: Yes, it has the same functionality. Make sure to compare the continuous amperage rating on this relay vs. what you're controlling. Motor inrush may be an issue, but is avoided with PWM control.

**Q: Will this turn 12 volt dc on and off**
A: yes it will, the trigger voltage is 12 volts as well

**Q: How much current is required to activate this relay?**
A: Not sure how much current. On a hay baler the computer activates it. I don't believe much current come from the computer.

**Q: Is this a positive or negative triggered relay I want to use it for pulse-width modulation of a fuel pump**
A: Negative.  Be sure and look at the wiring diagram as its not a direct drop in for a standard relay.  It will plug in but won't work right wihtout changing some wires. ....which I learned by installing it without looking at the diagram and wondering why it wasn't work right.  Wired per the diagram it does exactly what it's supposed to do.  I am also using it for PWM to a fuel pump.

Bought these relays, did not wire my ECU correctly and thought the issue was these relays, the issue was caused by not adding a power to Pin A26 on my Haltech Elite ECU, these relays would have worked great and would have been reliable, unfortunately I returned them.

### ⭐⭐⭐⭐⭐ Awesome!
*by D***G on March 15, 2025*

Works Great! Converted dome lights from on/off to a pulse width modulated dimming effect. Standard relays buzz as the pwm signal is activated. Installed this solid state relay and now there is no more buzzing but a smooth silent dimming effect. Would buy again.
