We have several CDM-570L 24VDC or 48VDC BUC Power Supply modules for sale.
Not all CDM-570L modems are purchased with a BUC power supply, or in other cases the modem may have a 24V installed, but require 48V power supply instead. Either way, in a few minutes one of our power supplies can be easily installed in the CDM-570L.
We have several used 24VDC modules, saved as a result of upgrading the modems from 24VDC to 48VDC. Our 48VDC modules are brand new.
These power supplies are manufactured by Cosel, but beware of buying them direct because Comtech made some enhancements that allows their software to enable or disable the output. Without these changes the power supplies will not function correctly in the modem.
