    ±1% of the preset level from no-load to the full specified load, over the specified mains voltage and temperature ranges (refer to Section 7.6). The T807/808 power supply is designed to power T800 series base stations. Specifically, the T807 will power 50W base stations, while the T808 will provide the current require- ments for 100W base stations.
