This is why the transformer may sometimes energize without a problem and other times it will blow the fuse or trip the circuit breaker.

Because we are a major distributor for some products, we price very aggressively by sacrificing profit margin whenever we sell in bulk. The philosophy to offer quality products with little mark up has created unmatched customer loyalty for some successful membership based stores. Unlike those wholesale to public membership clubs, we do not charge any membership fee. Some merchants offer FREE shipping, but when you buy quantity 10, you pay 10 times total. Essentially, you are paying 10 times on shipping. We don't think that is fair to you. Why? Most of the time, shipping a 10 lb parcel does not cost 10 times of a 1 lb parcel.

Here is an example:

Don't be shy. If you discover any competitor outselling us in a particular product, whenever you purchase in large quantity, please bring it to our attention. Most of the time, we will match or beat their price, and give you a credit. If we lose to a competitor, it is our shame. We then know we need to work harder in sourcing to create values for you.

* Price comparison must be based on comparable brands or models and in bulk quantity purchase.

Product Description

Manufacturer Part Number: P-T1182-9

Dual 117/234 VAC primary, 50/60 Hz. operation. 18 V series, 9 V parallel secondary.

Toroidal transformers are

low profile
lightweight
cool running / high efficiency
have low stray magnetic flux leakage (low EMI) due to core shape

Features:

Supplied with two neoprene rubber insulating pads, one metal centering washer and all mounting hardware
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

Note: Units are designed to have all windings engaged (either series or parallel connected) or connected as an autotransformer.

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.
