Supporting 12V to 48V DC systems and up to 10A current, it’s ideal for critical devices like incubators, laptops, and network equipment. Featuring easy screw terminal connections and IP54 protection, it ensures reliable, hassle-free emergency power management for professionals who demand uninterrupted performance. ## Description Characteristics: This controller is used to change the emergency battery; when there is power in the terminal of the main Power Source, it will be connected to the main power source as a power source; Otherwise, it will automatically change to the battery. When the main power source is back, it will switch to main power. Designed with screw terminals for a convenient cable connection. Convenient to use, it will automatically identify the voltage between 12V and 48V DC. Widely used to control the Power Source of the incubator, portable, network. Specifications: Voltage: DC12V ~ 48V Charging current: 10A Size: 5 * 3 * 1.8cm / 1.9 * 1.2 * 0.7in Quantity: 1 Weight: 22g (approx.) Note: 1, the voltages of the Power Source, the battery and the must be equal. 2, when it is turned on, there will be a temporary power failure for less than 1 second. Package includes: 1 x driver Review: Works as expected. Good quality - I’m using this for a little different application. Instead of switching to a battery back up, I’m switching off of batteries to an AC/DC converter. My son-in-law is using solar power to run a 24vdc pump for his hydroponics system, but if he has no sun for a few days, the batteries don’t get charged enough. I set this up to switch power to an AC/DC converter when the battery level gets too low to keep the pump running. It’ll switch back when the batteries get a sufficient charge. Essentially, I am using the Shelly relay and MQTT to do the switching. Do note, as others have mentioned, there is a delay of about a half a second in switching between the two sources. This is not a problem with the pump. It may be for more sensitive electronics. Review: Diesel Heaters dot like this switch - Diesel Heaters do not like this switch as the delay in switching over to battery backup is to long, Causing unit to shut off and smoke out. This switch would work on something that isnt so fragile to voltage disruption. ## Features - ★★★【Used for】This controller is used for emergency battery switching; when there is power on main power source terminal, it will connect to main power source as power supply; otherwise, it will automatically switch to battery. - ★★★【Features】When the power on main power source is back, it will switch to main power. - ★★★【Easy to Use】Designed with screw terminals for convenient wire connection.Convenient to use, it will automatically identify voltage between 12V and 48V DC. - ★★★【Widely Used】The power supply controller is widely used for controlling power supply of incubator, laptop, network. - ★★★【After Sale】We supply fast and convenient return or replace service to insure purchasing without worries.
