interVOLT 12V Stabilizer/Voltage Regulator/Power Conditioner - Non-Isolated, Heavy Duty, Rugged, 12V/5A (62W) Switchmode Converter - Model SVS1212050

Used to provide protected clean 12VDC voltage to electronics in my RV. Works well in every regard. I inadvertently blew the SMD input voltage fuse (12 volt 12 amp L Type Chip Fuse) and had to contact Intervolt for the specs for this fuse which resides in line with the +12VDC input terminal (see photo). They were kind enough to quickly provide me with the information twice (lost the email the first time). For anyone needing to acquire the SMD fuse the fuse is an L type Chip Fuse with a part number of CQ12LV 012. You can order the replacement from Mouser Electronics. I post this because the manufacturer was not pleased that I had to ask twice for the information. Figured I'd post the part number so you don't have to bother them for the information. The Digi-Key replacement part/order number for a comparable chip fuse is:1206SFH120F/24-2CT-ND

I needed something to be able to regulate the varying voltage I was getting from the house battery in my RV. Tv/dvd player was not liking the power fluctuation and I had to do something about it so I didn't damage anything expensive! I tried some less expensive dc/dc step-down converters, but these were just noisy as soon as the voltage was different and nothing was able to handle the amps that my tv and dvd player were drawing. I decided to drop the extra money and buy this thing so I could prevent disaster on my electronics and SO glad I did. I have my power going to this stabilizer, then to a cigarette lighter/volt meter so I can monitor how many volts are going to the cigarette lighter. Just like I wanted, I am getting a CLEAN 12.4-12.7 volts all the time. If the battery is too low to maintain 12.5 volts, the unit will shut off automatically and attempt to restart (letting you know its time to charge the battery). After days of searching for the right device to stabilize my power, I'm wishing I had gone with this sooner. If your situation is like mine, cough up the change and get this. You won't regret it.

The item may work OK, but it does not output the voltage that they indicated in one of their charts so I returned it. It did seem to put out a solid 12 - 12.4 volts.

Works great. Would recommend to anyone

Small and easy to install. Very consistent 12.4 volts in my application.

Works like a champ. Installed in an RV to power an aftermarket 32" tv. Wall wart power supply for the tv was 12v 5a output. This replace an inverter and wall wart power supply perfectly. Tv is rock solid on house batteries. Previous set up had issues if the RV wasn't plugged in or running. I don't have to listen to the inverter fan either.

Used this on my car computer in my GMC Savana. The Voltage in the car is 13.5-14.5, the Pico PSU only operates 11.5-12.5, so it would intermittently turn on, then shut off low when it was on. This operates at 12.5 according to my Fluke, and stays at 12.5. I did put a 1 farad capacitor on it as well. Works beautifully. Also removed audio noise coming from the computer because the power is now clean and regulated.

So it works. Power from battery 10-14.8 to a stable 12.5 volts. Only gripe is it is not silent. Has a high pitch whine that comes from the device. I can hear it as soon as I entry the room it’s in. Constant high freq whine no matter if device is under load or not. For reference I use it to power a 24” 12v2amp monitor and a minix 12v1amp pc. Unit stays cool and no issues running extended 24hours plus.
