Little FOCer Rev3.1 ESC Electric Speed Controller BYOH (Bring your own Heat-sink version)
The capacitors and JST connectors' are mounted on the opposite sides of the mosfets so that the motor controller can be mounted to a metal plate or other custom heat sink solution. This is typically the best option for fitting inside the controller box of a balance board.
New features in Rev3:
Specification | Value |
Nominal Input Voltage | 28V to 72V (8s to 20s Lithium Ion) |
Recommended Lower voltage limit | 24V |
Absolute Maximum Operating Voltage | 84V |
Battery Current Consumption |
Off=500µA Idle< 0.8W Max (ext.) = 100A |
Peek Phase Current | 250A |
Peak Efficiency | 95% or greater |
PET PWM switching frequency range | 10kHz to 60kHz (Center Aligned PWM) |
