The Toroid Power Transformers 1182 Series features include: - Low profile design - Lightweight construction - Cool running and high efficiency - Low stray magnetic flux leakage due to the core shape (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 - Minimum 8" long flexible leads - 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 leading to high magnetizing current when initially energized - Recommendations for using slow-blow fuse, time-delayed circuit breaker, or soft start circuitry for supply line when using these transformers Toroid Power Transformers 1182 Series replaces the older 182 Toroid Series .

To address the issue of inrush current when using Toroidal transformers, it is recommended to consider using a slow-blow fuse, time-delayed circuit breaker, or other forms of soft start circuitry for the supply line. This is 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 limited by the low DC resistance of the primary winding and is rarely longer than half of a cycle. Depending on where you are in the AC cycle when the transformer is energized, there is a chance of overloading the supply circuit, which may result in blowing the fuse or tripping the circuit breaker. Therefore, implementing measures such as a slow-blow fuse or time-delayed circuit breaker can help mitigate the effects of inrush current on the supply circuit.
