Product overview
The ZHTAERO PDB-70A is a power distribution board for integrating electrical power management into industrial drones, robots and automation equipment. Its role covers devices such as flight controllers, electronic speed controllers and gimbals. The compact module combines a current sensor, optocoupler control, power and step-down modules, an ESC signal line and an LED. Its dual-redundant designation accompanies three independent voltage outputs, giving system integrators separate supply connections for flight electronics, sensors and mission payloads.
The board accepts 30-63V DC input from a 6-14S lithium battery and provides two 5.4V outputs plus one 24V output. It weighs 58.8g and supports a maximum continuous current of 70A; the peak rating is up to 100A for 10 seconds. Integration provisions include dedicated flight control interfaces, assembly line interfaces and pad connections for high-current ESC, input and output wiring. Flight controller compatibility is identified for PX4/ArduPilot (Pixhawk), making those systems a stated integration target.
