Hdc-4000w is the special governor of high-voltage and high-power dc motor. Suitable for permanent magnet or excitation brush-dc motor! Model: HDC - 4000 w Power: 3500W rated current: 20A Output voltage: DC (DC) 0~240V [maximum output voltage adjustable] Input voltage: AC (AC) 85V~265V Speed range: 1-9999 RPM [actual speed is determined by the motor] Size: length :170mm* width :155mm* height: 70mm Applicable motor: 48 v/DC36V / 60 v / 72 v / 90 v / 100 v / 110 v / 180 v / 200 v / 220 v dc motor ¡½ ¡¼ If the power tube breaks down short circuit, then the 310V voltage is directly loaded on both ends of the motor, causing the phenomenon of motor flying; Even the whole mechanical equipment damage; If the circuit does not have the function of overcurrent protection, too much current will burn down the circuit board and even cause production accidents such as fire.
The governor of our shop has made great efforts in [safety protection measures] and has multiple protection mechanisms: [lightweight:] single-chip software current limit and software voltage limit protection; [heavyweight:] hardware current limit, when the current reaches the maximum set value, the governor can directly turn off PWM output, when less than the set value, and automatically open PWM output, play motor overcurrent protection, which can effectively protect the motor and power tube; [excess level:] when the hardware protection fails to work, directly cut off the motor power supply circuit through the control relay; Emergency shutdown; [if braking resistance is increased, emergency stopping effect is more obvious] [destruction level:] when the circuit board appears short circuit, wiring errors and other destruction level failure, fuse burning off can quickly cut off the ac input, so as to prevent further expansion of the fault;
Taobao, the vast majority of speed plate are not attached to the governor protection function; Simply add a fuse as the entire circuit board protection measures Here, I teach dear friends a simple method of identification. Just look at the circuit board, is there a relay, is there a current sampling resistor on the circuit board? If there are no two components, there is absolutely no protection;
