Hammond Transformers Model 1182K240 (1182 Series)
Toroid Power Transformer - 300 VA, 240V C.T. @ 1.25 A
The benefits of Toroidal transformers are their lightweight, low profile, cool running and high efficiency. Due to their core shape there is low stray magnetic flux leakage (low EMI). These units are designed to have all windings engaged (either series or parallel connected) or connected as an autotransformer.
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 Download Section for Connection Sheet.
- 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
- This series replaces Hammond’s 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 efficiency Toroidal transformers.
