1182S30

The Toroid Power Transformers 1182 Series features 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 two rubber insulating pads, one metal centering washer, and all mounting hardware (except the 1,500 VA size) - 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, requiring precautions such as slow-blow fuses or time-delayed circuit breakers for the supply line Toroid Power Transformers 1182 Series replaces the older 182 Toroid Series . In summary, the Toroid Power Transformers 1182 Series offers various features such as low profile design, high efficiency, dual primary operation, and safety certifications. Additionally, precautions need to be taken due to the high magnetizing current when initially energized.

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

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 a cycle. Depending on where you are in the AC cycle when the transformer is energized, it can either energize without a problem or blow the fuse/trip the circuit breaker. Therefore, precautions such as using a slow-blow fuse or time-delayed circuit breaker are recommended to prevent overloading the supply circuit.
