1182U24

Some features of the Toroid Power Transformers 1182 Series mentioned in the document include: - Low profile and lightweight design - Cool running and high efficiency due to the core shape, resulting in low stray magnetic flux leakage (low EMI) - Dual 117/234 VAC primary, 50/60 Hz operation - Designed to have all windings engaged (either series or parallel connected) or connected as an autotransformer - Supplied with rubber insulating pads, metal centering washer, and mounting hardware - 1,500 VA size is supplied with a potted center for extra strength - Manufactured using Class B (130 degree C) materials - Hi-Pot test of 4,000VAC RMS between primary & secondary - UL recognized to UL506 (XPTQ2.Guide) UL file #E207860 - CSA certified to C22.2 #66 - CSA file #209651 - CE compliant to IEC 61558-2-4 - Superior magnetic properties make them susceptible to high magnetizing current when initially energized - Recommendations for using slow-blow fuse, time-delayed circuit breaker, or other soft start circuitry for the supply line when using these transformers Toroid Power Transformers 1182 Series.

The issue of inrush current when using Toroidal transformers can be addressed by considering using a slow-blow fuse, time-delayed circuit breaker, or other forms of soft start circuitry for the supply line. This is recommended due to the superior magnetic properties of Toroidal transformers, which make them susceptible to high magnetizing current when initially energized. The overload caused by inrush current is usually short-lived, lasting rarely longer than half a cycle, and can sometimes lead to blowing the fuse or tripping the circuit breaker. Therefore, implementing measures like a slow-blow fuse or time-delayed circuit breaker can help mitigate the impact of inrush current on the supply circuit.

The primary voltage for the Toroid Power Transformers 1182 Series is dual 117/234 VAC, and the frequency is 50/60 Hz.
