The Tigo Data Loggers require a power supply whose output voltage is 24 VDC with at least 1 amp of current capability.
Tigo sells power supplies that plug into a standard 120/220 VAC household electrical outlet, and also 'hardwired' to a circuit breaker.
Any power supply providing a well-regulated 24 VDC voltage with at least 1 ampere of output current (so output power of 24 Watts) can be used, as long as it has the specified Output Connector size for an MMU. CC and CCA do not use a plug, and any replacement can just have the plug removed.. Recommend to be UL and FCC approved.

Replacement directions:
To open the clear cover, rotate the slotted screw that has the screwdriver on it in the below picture counter-clockwise 90 degrees, then press Thumb Bars upward, and swing the cover open.
Next, remove the MMU Access Panel by removing the screws in the bottom corners, and pull it out.
In the below picture, see the Barrel plug power supply connector location, which is on the left most side.
Unplug that connector from it's socket.
The cables run through glands on the bottom of the enclosure. Loosen the gland cap by rotating counter-clockwise until it is loose and can slide down the cable.
Remove the original power supply DC connector by pushing it through the cable gland inner sleeve. This is easy to do and will not damage the unit, or the cable.
