[APISQUEEN Professional Guide] Bidirectional ESC & Unidirectional ESC: Analysis of the differences between 30A ESC and 80A ESC

As a professional underwater propulsion system supplier, APISQUEEN explains the key technical differences of splashproof ESC. Our 30A splashproof bidirectional ESC and 80A splashproof unidirectional ESC have been successfully applied in special equipment fields such as underwater robots and submersible thrusters.

1. Bidirectional ESC Operation Guide (Taking APISQUEEN 30A splashproof bidirectional ESC as an example)

Recommended application: underwater operation scenarios that require precise reverse control

Use 16V power supply to connect 30A splashproof ESC

Connect the propeller three-phase line through the waterproof connector

Pay attention to the white line direction mark when the signal line is connected to the receiver channel 

After completing the self-test, the remote control joystick can be pushed up and down to achieve:

Push up: propeller forward thrust (device forward)

Pull down: reverse airflow (device backward)

Technical advantages:

Instantaneous reverse response speed <0.2 seconds

Support PWM control protocols

2. Unidirectional ESC Operation Guide (APISQUEEN 80A splashproof unidirectional ESC solution)

Typical application: high thrust unidirectional propulsion system

Before connecting the heavy-duty 80A splashproof ESC, make sure the knob is in the 1ms position

Connect the three-phase line 

Keep the white line downward when connecting the signal line 

The knob linearly controls the 0-100% thrust output

Performance highlights:

Peak 80A load continuous and stable output

nano waterproof coating
