Low voltage transformers
- Voltage transformers
Due to their physical structure, the low voltage converters are particularly surge-proof and highly efficient. They also offer class-accurate harmonic transmission up to 10kHz.
Our production range includes single-pole insulated voltage transformers for connection between conductor and earth and two-pole insulated voltage transformers for connection between conductor and conductor.
Performance characteristics
- • Primary nominal voltage range from 100/√3 V to 1000/√3 V respectively 100 V to 1000 V
- • Secondary nominal voltage 100/√3 V respectively 100 V
- • Accuracy class: 0.2 / 0.5 / 1
- • Protection class: 3P / 6P
- • Low internal consumption of the voltage transformers thanks to powerful toroidal cores
- • Ideal for use with up-to-date measuring devices, since an under-burden in load area 1 (according to IEC 61869-3) is excluded
- • Simple connection (primary and secondary) via screw connections M5 x 8
• Nominal frequency: 50 or 60 Hz
• Highest voltage for equipment, Um
- for Upr ≤ 600/√3 V respectively 600 V: 0.72 kV rms
- for Upr > 600/√3 V respectively 600 V: 1.2 kV rms
• Permanent operating voltage: 1.2 x Upr
• Rated voltage factor FV: 1.9 x Upr / 8 h (VTLS)
• Insulation class: E
• Operating temperature range: - 5°C … +50°C
• Operating temperature range: - 5°C … +50°C
• Storage temperature range: -40°C … +85°C
• Protection class acc. to IEC 60529: IP 20
• Weight: approx. 2.13 kg
