Adjustable 24V DC power
Hi all,
I need some help here. I want to verify a voltage "trip" point on a board that operates on battery supplied 24vdc. The maximum draw is about 600MA The board should change to "recharge required" at 22VDC My thought is to put some sort of resistor in line on the main battery feed so I can slowly reduce the voltage to a point where it trips the recharge indicator. A voltmeter after the resistor would allow me to monitor the voltage level where the recharge indicator is activated. I am not an electronics guru (obviously) so something "off the shelf" would be great. Maybe some type of adjustable resistor? Any ideas? Thanks. |
