Used to fix battery issue in Sentry 3.1 call blocker. Pure sound power.

Limitations are the weak springs of the battery holder and the fact that the batteries suddenly fail and block the entire telephone system. Revain's new DC/DC converter delivers true DC power with ultra-low ripple for battery swapping. Regular AC adapters create annoying noise on the phone line, so you need a very low ripple voltage. This device offers it (DZS Elec DC 4A Step-Up Down Power Supply Module DC-DC 4.5V-30V) for $10. Set to 5V DC and plugged into the back of the Sentry you get clear…

Pros
