   Series UPS-MTE devices are intended to ensure the uninterrupted power supply for MikroTik routerboard, which have the supply voltage in range from 10V to 28V. (the models of MikroTik routerboard: B411/411A/411AH, RB433/433AH/433UAH, RB450/450G, RB33, RB493/493AH)
   These devices can work in conjunction with the UPS-MT-monitor, which is installed on the routerboard.
   The devices must be equipped with an additional battery, the battery voltage of 12V for UPS-MTE-12 and 24V for UPS-MTE-24.
   The capacity of the battery may be chosen based on customer requests, and can be located in the 2,3...30AH.
   Note that when high-capacity battery increases considerably the time of their charge.
   Recommended by 7AH for UPS-MTE-12 and 2,3AH (12V, 2pcs) for UPS-MTE-24.
   In joint work with the UPS-MT-monitor settings are correct:

supply voltage of routerboard,
state of supply voltage network of UPS – оn/off
temperature inside the enclosure, where routerboard.
