AC90V-260V Input DC90V 110V 180V 220V Output 8A PWM Motor Speed Controller Drive Features1. the input power (VAC): AC90-260V 50/60 Hz (Wide voltage range) 2. the output armature voltage range (VDC): 0-90V/110V/180V/220V (can be customized different versions) 3. the output armature current range (A): 8A (0.1A-10A can be arbitrarily set) If the current is too large need to increase the heat 4. the output excitation voltage range (VDC): 100V/200V (default full bridge rectifier, which is 0.9 times the input voltage) 5. the output excitation current range (A): 1A 6. the operating frequency: 16 KHz 7. the given signal mode (V / mA): the default potentiometer, 0-5V, 0-10V, 4-20mA, PWM, button type 8. enable control mode (EN): switch 9. soft start (acceleration time adjustment range) (S): 0-10S (default3 seconds)10. soft stop (deceleration time adjustment range) (S): 0-10S (default 3 seconds) 11. double closed-loop PI regulation, (voltage, current) control more reliable 12. IR torque compensation range: 0-100% (default 0) 13. over-current protection range: 0-set value (default 8A) 14. over-current protection: stop the output and instructions (display code E1) 15. short-circuit protection: stop the output and instructions (display code E0) 16. overheating protection: power tube temperature exceeds 100 ° turn off the output and instructions (display code E2) 17. built-in digital display module, can display real-time operating voltage and current 18. Dimensions: length 159mm × width 98mm × height 38mm 19. wiring: terminal type (convenient) Advantages1, using pulse technology to speed more stable, low speed forceful2, with a short circuit, overcurrent, overtemperature protection cutoff device to make more reliable performance3, with the elimination of soft starter motor starting current is too large4, high and low voltage signal is completely isolated, the use of safer Precautions1, the governor closed the input power,Touched by hand within a minute ban high-voltage terminal,There are high-voltage capacitors,To prevent electric shock!!!2, for the two lines of DC permanent magnet motor,Two lead wires connected directly to the armature M + with M-.Prohibit access exciting!
