Great for converting drive wheels to 20v

Used this relay along with a low voltage cutoff board to convert drive wheels to Dewalt 20v. Easy assembly with additional screw hole.

Pros
  • Automotive
Cons
  • I vaguely remember

Switching from 14 VDC to 21 VDC when converting Power Wheels

This relay was used when converting Power Wheels from 12 VDC to 20 VDC. The vehicle will not operate on Dewalt 20V DC power tool batteries. The undervoltage lockout removes power from the relay coil when the battery voltage drops to 14 VDC. The coil works easily in the range of 14-21 VDC. The relay works well with standard fastons. Has a very low profile. Easy to assemble. Highly recommended.

Pros
  • Relay
Cons
  • Cable shorter than others

Decent, reliable, a lemon out of ten is not bad

I used them in a special control unit for lighting and fans. 40 A is the absolute maximum for resistive loads, while inductive loads are slightly reduced. Of the ten relays, one mysteriously failed, that is, it still switches, but the closed resistance between the contacts was about 3 ohms, at a current of 10 A the relay literally melted and smoked. Otherwise I had no problems. I wouldn't swim with them, but they survived the heavy rain when a terrible storm ripped off the roof of the control…

Pros
  • Accessories Power
Cons
  • Little things
