Input voltage ranges
Depending on the model and nominal power, the inverters are designed for direct connection to the following voltage sources:
MOVITRAC® LTP-B | |||
|---|---|---|---|
Nominal voltage according to EN 50160 | Power | Connection type | Rated frequency |
200 – 240 V ±10% | 0.75 – 2.2 kW | 1-phase* | 50 – 60 Hz ±5% |
200 – 240 V ±10% | 0.75 – 75 kW | 3-phase | |
380 – 480 V ±10% | 0.75 – 250 kW | ||
500 – 600 V ±10% | 0.75 – 110 kW | ||
480 – 525 V ±10% | 132 – 200 kW | ||
Units that are connected to a 3-phase supply system are designed for a maximum power grid imbalance of 3% between the phases. For supply systems with a power grid imbalance of more than 3% (for example, in India and parts of the Asia-Pacific region including China), SEW-EURODRIVE recommends that you use input chokes.
INFORMATION
* It is also possible to connect the single-phase inverter to 2 phases of a three-phase power supply system of 200 – 240 V.
INFORMATION
All inverters with degree of protection IP20/NEMA 1 and IP55/NEMA 12K with a 3‑phase power supply can also be operated in a single-phase configuration with the corresponding line voltage at device terminals L1 and L2, taking into account a derating of 50% of the output current. Application example with SWER (Single-Wire Earth Return) supply systems.
Excluded from this control type:
- Inverters with degree of protection IP66/NEMA 4X
- Inverters with degree of protection IP55/NEMA 12 with the power ratings 200 kW and 250 kW
- Inverters with a voltage of 3 x AC 480 – 525 V
