ETUS Series Voltage Transformer
Leave a Message
The ETUS Series Voltage Transformer is engineered for precise voltage conversion in electrical testing applications, facilitating compliance with international power quality standards including IEC 61000-4-11. This transformer converts single-phase 110/120V or three-phase 220V/240V input voltages (common in North American and Japanese systems) to single-phase 220V or three-phase 380V output voltages (standard in Chinese and European systems). Output voltage stability is maintained at ±1% of input voltage stability, ensuring consistent power delivery for sensitive test equipment.
When paired with the ITEU-SP4K Isolation Transformer, this system provides pure, stable, and isolated power essential for electromagnetic compatibility (EMC) testing, product validation, and laboratory applications. The isolation transformer eliminates ground loops and reduces electromagnetic interference, creating an optimal testing environment.
| LISUN Model | Input Voltage Configuration | Output Voltage Configuration | Power Rating |
|---|---|---|---|
| ETUS-SP2K | Input: Single-phase L/N, 110V nominal (100V or other voltages configurable) | Output: Single-phase L/N/PE, 220V nominal | 2 kVA |
| ETUS-SP5K | Input: Single-phase L/N, 110V nominal (100V or other voltages configurable) | Output: Single-phase L/N/PE, 220V nominal | 5 kVA |
| ETUS-TP10K | Input: Three-phase A/B/C, 240V line-to-line (other voltages configurable) | Output: Three-phase L1/L2/L3/N/PE, 380V nominal | 10 kVA |
| ETUS-TP20K | Input: Three-phase A/B/C, 240V line-to-line (other voltages configurable) | Output: Three-phase L1/L2/L3/N/PE, 380V nominal | 20 kVA |
| ETUS-TP30K | Input: Three-phase A/B/C, 240V line-to-line (other voltages configurable) | Output: Three-phase L1/L2/L3/N/PE, 380V nominal | 30 kVA |
| ETUS-TP40K | Input: Three-phase A/B/C, 240V line-to-line (other voltages configurable) | Output: Three-phase L1/L2/L3/N/PE, 380V nominal | 40 kVA |
| ETUS-TP60K | Input: Three-phase A/B/C, 240V line-to-line (other voltages configurable) | Output: Three-phase L1/L2/L3/N/PE, 380V nominal | 60 kVA |
| ETUS-TP80K | Input: Three-phase A/B/C, 240V line-to-line (other voltages configurable) | Output: Three-phase L1/L2/L3/N/PE, 380V nominal | 80 kVA |
Technical Note: The voltage step-up transformer exhibits an efficiency rating of 55-60%. Therefore, for equipment under test (EUT) requiring 10 kW of power, selection of at least the ETUS-TP20K model (20 kVA output rating) is recommended to account for efficiency losses and ensure adequate power delivery.
