Posted: May 21st, 2012, 11:24 pm
Hi all, I was out shopping for parts and pieces for my build today and visited the local military surplus outfit. You just never know what treasures might be lying around. Anyway I spotted this small box on a shelf amongst a heap of various electronic stuff and when I opened it discovered a CURTIS PMC Model 1203A-501. It was brand new in the box but without any literature. I didn’t have a clue what it was but it had B+ and B- pins on it, M1 and M2 pins ( I assumed M = Motor) and other connection pins indicating "POT". I did find a few tid bits of information on it online. It’s a DC reversible motor speed controller!!! And one heck of a controller at that. I was not fruitful locating a manual as yet and I am asking if anyone has information on them. I think it is rated from 24 to 36 vdc and up to 50Amps. For the whooping fee of $15.00 I think I scored big time. I also scored a entire box of sonar sensors and controller boards. Some of the sonar boards are for up to 4 sensors and some for up to 2 sensors. They were designed as safe backing sensors that beep via a small horn the presence of obstacles starting at 6 feet, then faster beeping at 3 feet and then a steady tone at 2 feet or less. I'm not sure of any ROV uses but I thought they might be useful operating in poor visibility as you approach the bottom when descending.
