Power supply for modems

Power supply for modems

Product description

PSM90 is a switching power supply specially designed to work with GSM, GPRS, 3G, 4G, 5G and LTE modems, taking utmost care of their performance and ensuring the best service.

In remote control applications, it is essential to guarantee communication as much as possible since it is vital to prevent communications from being blocked or modems from deteriorating under certain circumstances.

PSM90 automatically and periodically cuts the modem's power supply to reset it, thus preventing a possible blockage of communications.

It is remarkable that the power supply has internal protections at the voltage input and output to take utmost care of the modem, giving it a longer useful life.
