General-Purpose VFD Variable Frequency Drive 3AC 380V~460V 0.75KW~630KW
KD330 series Variable frequency drive is a universal high-performance drive
vector control function frequency converter. Based on the advanced technology control theory and intelligent control means, the inverter-controlled speed control system achieves extremely high responsiveness and stability. Better meet the different needs of various industrial control occasions.
Items | KD330 | |
1 | Reliable hardware | Only first-class componens are built-in. |
2 | Rubust design | IGBT current > 2 times of inverter output current |
Capacitor > 50uF/A | ||
3 | PCB aging test | 100% test, 50°C, 12 hours. |
4 | Finished products aging test | 100% test, 50°C, 24 hours. |
5 | Loading test | Two times, 100% tested: |
1. After manufacturing. | ||
2. After aging test. | ||
6 | Grouped pulse testing | Without failure under 4500V (better EMC performance). |
7 | Electrostatic testing | 1. Noncontact conditions -- without failure under 10000V. |
2. Under contact condition -- without failure under 5000V. | ||
8 | Unqualification during production | <0.03% |
9 | Total failure ratio at industrail sites | <0.5% |
10 | High overload capacity | 150% / 120s, 160% / 60s, 180% / 10s, 200% /1s |
11 | Smart start / stop mode | Acceleration / Deceleration time can be set as 0.0s, the inverter
starts and stops the motor as fast as possible without failure. |
12 | S ccure Acceleration / Deceleration mode | Better start stop performance. |
13 | Big start torque | 0.5Hz/150% (V/f), 1Hz/150% (SVC) |
14 | Better stop performance | 1. Current is limited smoothly while stoping; 2. Stops smoothly in
very short time for heavy load applications. |
15 | Better input voltage flexibility | -15%~+15% without failure. |
16 | LED display | >7,5kW, two lines parameters dispaly, convenient for
commissioning and operating. |
17 | LCD display | Under developing |
18 | EMC filter | C3 level EMC filter build-in standardly |
