Variable Frequency Drive: Features
No. Items KD330 1 Reliable hardwareOnly first-class componens are built-in.
2 Rubust designIGBT current > 2 times of inverter output current
Capacitor > 50uF/A 3 PCB aging test100% test, 50°C, 12 hours.
4 Finished products aging test100% test, 50°C, 24 hours.
5 Loading testTwo times, 100% tested:
1. After manufacturing.
2. After aging test. 6 Grouped pulse testingWithout failure under 4500V (better EMC performance).
7 Electrostatic testing1. 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 capacity150% / 120s, 160% / 60s, 180% / 10s, 200% /1s
11 Smart start / stop modeAcceleration / 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 modeBetter start stop performance.
13 Big start torque0.5Hz/150% (V/f), 1Hz/150% (SVC)
14 Better stop performance1. 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.
