TP-P3-80024 is a high-voltage isolated DC/DC power module for tethered UAV power chains that require a 24V-class regulated output. The detailed electrical tables specify a 680–800VDC input range, 25VDC rated output and a 21–25.2VDC output range.
The module is specified for 3.5kW maximum output with 120A rated current and 140A maximum current. Its compact heat-sink envelope, built-in air cooling, IP54 protection and -40°C to +50°C operating range support engineered integration where voltage compatibility, cooling airflow and payload margin have been verified.

TP-P3-80024 must be selected against the aircraft's full 24V bus range, continuous and transient current, backup-battery behavior, tether voltage drop, connector rating, installation airflow and payload margin. The 3.5kW figure is the maximum output documented in the detailed electrical table; it should not be treated as a blanket continuous-duty approval for every aircraft installation.

Answers to common compatibility, configuration, quotation, and delivery questions.
The manual overview contains generic 4,000W wording, but its product specification and detailed electrical table both state 3,500W maximum output. The published page follows those repeated detailed tables.
The detailed electrical table specifies 25VDC rated output with a 21–25.2VDC output range. The aircraft bus and backup-battery interface must be checked before installation.
The manual references a shared current bus and parallel output connection for up to eight units. Current sharing, protection coordination, cable sizing and the final unit count must be engineered for the project.
The manual specifies IP54 protection, built-in air cooling and a -40°C to +50°C operating range. Installation orientation, airflow, condensation control and the actual mission environment still need review.
