Technical features:
1. Wide voltage range input
Power voltage: -15% - 10%, 47 Hz - 63 Hz; provided with under-voltage underclocking output function that extends the applicable range of power voltage to -30% (e.g. extending the applicable range of a 380 V VFD to 266 V - 440 V);
2. High disturbance resistance
Pulse group tests: ± 4,800 V
Static (air discharge): 8,000 V
Static (contact discharge): 6,000 V
Provided with EMI circuit + lightning protection design
3. Phase-phase and phase-to-earth short circuit protection
Any phase-phase short circuit protection < 8uSec U, V and W phase-to-earth short circuit protection;
4. Anti-corrosion treatment
8 µm nickel plating, and three layers of British conformal coating for key parts;
5. Power source of control signals:
External power supply of +10 V and +24 V, both provided with short circuit protection.
The +10 V power supply is provided with a current output of 30 mA.
The +24 V power supply is provided with a large current output of 200 mA
6. Overload capacity
The Type G VFDs of all series have an overload capacity of one minute under 150% of overload, while for Type L, one minute under 120%.
7. Comprehensive configuration
Supports an extended relay board: four extended relays (T3 - T4) and one Y terminal (Y3), supporting up to 6 relay outputs; and for CDE360-4T30G/37L and lower types, a built-in braking unit is provided.
8. Revs tracking
Smooth tracking that is successfully completed in one time is guaranteed, whether the motor is revolving forward or backward, and the revolving speed high or low.
9. Non-stop operation during instantaneous power failure
On the occasion of a municipal power failure, the VFDs can remain operating based on their energy feedback; the low voltage ride through (LVRT) can be realized.
10. Low-frequency current output is highly close to sine with large torque.
0.5 Hz, the motor can output 100% of its rated torque.
11. Premium rapid start and shutdown performance (1 s, acceleration and deceleration).
