I have ordered three of these 25 amp units from revain, between May 2022 and June 2022, that have not worked and I have returned to revain. I have experience with the 20 amp units that regulated the dc input to 13.8 volts and worked perfectly. revain must have a bad run of these 25 amp units. I just ordered a fourth unit utilizing revains excellent return policy. I will update my rating if the fourth units actually works. Again this is a problem with the 25 amp units.Update 6/14/2022, I just tested the fourth unit that I received and it was also bad. I have returned all four. This is the 8-40 volt, regulated to 13.8 volts, 25 amps. DC840138-25.
