his drive is a DC three-phase brushless control board, which requires the motor to have Hall in order to work normally. This drive is only suitable for DC brushless Hall motors with an electrical Angle of 120 degrees. Support PLC 0-5V analog control. Support PWM control amplitude 2.5-5V. Working voltage: 6-60V (60V limit remaining) Working current: rated 16A 20A Power: rated 200-300W 500W (leave enough to strengthen heat dissipation when using high power) Overcurrent protection: yes (The product appearance and printed words depending on the batch, but this does not affect use) Color: As Shown Material: PCB Package Contents: 1 x Motor Drive Board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
