Input Voltage Range

The low-voltage (network voltage) standard values in Europe are established in IEC60038, being 230V (single-phase) or 3x400V (linked) with a tolerance range of +/-10%. BREMER transformers are designed to accommodate these tolerances unless otherwise specified or correction taps are intended.

Note: In user specifications, an input voltage indication of, for example, 230V +/-10% is often found. Clarification is then required as to whether this is intended to describe the input voltage range or express a desire for correction taps.

Therefore, we ask for precise formulation, e.g.,

• Input Voltage: 230V Input Voltage Range +/-10% or
• Input Voltage: 230V with taps for +/-10%

Note: BREMER transformers with positive taps are designed for a maximum input voltage according to the desired positive value. An additional addition with an input voltage range (tolerance range) would require agreement.
