?
The standard voltage AC 110V ~ AC220 System
?Speed Open-loop Control
?
A set of control IC models : LHS2401B
SSOP20 is Sensorless control main chip
SOP8 converts 0~5V voltage into 3.9KHz PWM output chip
?L X W : 110mm X 88.1mm
?LHS11025 has no overcurrent protection, use within 8A
?Choose not to mount the SOP8 conversion IC, which can be controlled by the B20K VR voltage directly input
(VR does not return to zero, the motor directly reaches the specified speed after power-on)
?
Select the SMD SOP8 conversion IC, the voltage signal is converted into PWM signal input control
(After power-on, VR must be reset to zero before it can control the motor to start)
?Lock Rotor Protect
?Please pay attention to be careful of short circuit, the experimental environment should be kept clear
