MTP250-53V47-OD can output 53V 250W, while the MTP250-26V94-OD (see related products) works with a 26V 250W output. Both power supplies come in a sturdy IP67 enclosure with extra protection from dust and moisture.
The voltage will depend on your setup – take a look at the “DC jack input Voltage” in the Power input specifications of the desired devices. In our example the home access points are designed for 12-30 V power supplies, so we are using the MTP250-26V94-OD. If you have a setup demanding higher voltage – like a net of PTZ security cameras, you could use the MTP250-53V47-OD instead. Always check the necessary voltage before powering your devices!
