Overview
TP-P3.5-80024 is an isolated DC/DC module for tethered UAVs with 680–800VDC input, 24 VDC nominal output (21–25.2 VDC range), 3.5kW maximum output, 120A rated current and 140A maximum current. TP-P3.5-80024 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, 24 VDC nominal output and a 21–25.2 VDC 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.
Features

System selection guidance
TP-P3.5-80024 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.
FAQ about TP-P3.5-80024
What is the maximum output power of TP-P3.5-80024?
The maximum output power is 3.5 kW.
What output voltage does TP-P3.5-80024 provide?
The detailed electrical table specifies 24 VDC nominal output with a 21–25.2 VDC output range. The aircraft bus and backup-battery interface must be checked before installation.
Can several TP-P3.5-80024 modules be connected in parallel?
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.
Is the module suitable for outdoor operation?
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.
