Toroid Power Transformers
1182 Series
Features
Torodial transformer benefits:
low profile
lightweight
cool running / high efficiency
due to the core shape - low stray magnetic flux leakage (low EMI)
Dual 117/234 VAC primary, 50/60 Hz. operation.
Note: Units are designed to have all windings engaged (either series or parallel
connected) or connected as an autotransformer. Connection sheet included with
transformer.
See Product Resources for Download.
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
This series replaces our older
182 Toroid Series.
Note about Inrush Current:
Due to the superior magnetic properties of Toroidal transformers they will be susceptible
to high magnetizing current when initially energized, only limited by the low DC resistance
of the primary winding. Depending on where you are in the AC cycle when the
transformer is energized dictates the chances of overloading the supply circuit. This is
why the transformer may sometimes energize without a problem and other times it will
blow the fuse or trip the circuit breaker. The duration of this overload is rarely longer than
a half of a cycle. Therefore, you should consider using a slow-blow fuse, time delayed
circuit breaker or other form of soft start circuitry for the supply line when using these high
efficient Toroidal transformers.
