1. Input voltage: AC95V-AC220V/50HZ, ultra-wide input voltage design (confirm the input voltage according to the motor voltage parameters)<br> 2. Convenient wiring, directly connect two AC input lines, connect the motor line, and adjust the potentiometer to adjust the motor speed. (Speed adjustment range: 0-maximum speed)<br> 3. Adopt high-quality elegant black double-sided FR-4 1.6MM thickness board design, PCBA adds slot design to enhance creepage distance<br> 4. The capacitor uses a power supply dedicated 450V/150uF high-frequency low-resistance capacitor (working temperature: minus -20°C-positive 105°C)<br> 5. The design reserves two sets of interfaces, VH3.96-6P (2 empty pins) interface & terminal interface, which can be used with the adapter board to connect 10 other interface motors<br> The module integrates input EMC anti-interference, -protection, negative temperature anti-overshoot design, and integrated non-isolated 15V motor power supply<br> Applicable to:<br> 1. Used to detect and test various types of DC variable frequency brushless air conditioners/fresh air/purification motors<br> 2. Used for DC brushless air conditioners/fresh air/purification motors, batch testing performance aging<br> 3. Used to modify or replace the original motor drive 4. Can be used with our store's motor test adapter board to achieve 10 types of motor interface drive<br> Different batches, the printed words on the board are random, and specified words are not accepted.
