Know the device!
· Enclosure options: IP20, IP55 options
· Safety STO SIL 2 integrated.
· Fire mode, PID, preset speeds
· Half-flush mount (90% heat outside MCC)
· 400V range from 1.5KW to 4MW
· Codesys custom logic via optional card
· When the temperature ranges from +40°C to +50°C, the rated output current is derated by 1% for each increased 1°C.
· EMC C3 with integrated filter, suited to EMC C3 with 30m shieled cable
Mains Side:
Incoming voltage range:
- AC 3PH 380V(-15%) ~440V(+10%),
- allowable frequency range: 47 ~63Hz
Fulfills EMC IEC/EN61800-3 category C2 or C3 in environment 1 or 2 depending on motor cable length:
- For EMC Environment 2 category C3 requirement, 30m shielded motor cable
- With additional EMC filter, the drive can achieve EMC Environment 1 category C2 requirement for 30m shielded motor cable
Harmonic, the standard offer: THDi ≤38% for 100% load for 18.5KW to 110KW, which is used to maintain an optimum power factor on the most common operating range
- Embedded low harmonic DC choke technology complying with standard IEC 61000-3-12 for the 380…440 V offer
Motor Side:
The GD350A operate with the following maximum motor cable lengths:
- With integrated filter, it is suitable for 30 m shielded cables.
- With dv/dt filter, the cable length can be extended to 250m shielded cable
- With sinwave filter, the cable length can be extended to 500m shielded cable
Output filters are used to limit dv/dt at the motor terminals to 500 V/μs maximum for supply voltages up to 440 V. Output filters are designed to limit overvoltages at the motor terminals to less than: 800 V with a shielded cable 0 to 50 m long for a 400 V supply voltage, 1,000 V with a shielded cable 50 to 150 m long for a 400 V supply voltage, 1,500 V with a shielded cable 150 to 300 m long for a 400 V supply voltage (up to 500 m with an unshielded cable).
