12 April 2015 Question by: Ian Bell
Q. Do these transformers come with a fixing kit?
A. Hi Ian. Thank you for your question. The fixing kit is included.


24 July 2014 Question by: Andrew Goloskof | Product code: 88-3801
Q. Item 88-3801 VTX-146-060-215 does not seem to be included in the PDF file from manufacturer. Have you the dimensions pleaee?
A. Hi Andrew. Thank you for your question. All the 60VA versions are the same size 34 x 85mm (height x diameter) as stated in the data sheet.


11 January 2013 Question by: Simon | Product code: 88-3844
Q. Does this have any form of EM shielding?
A. Hi Simon. Thank you for your question. These do not have any form of EM shielding.


03 January 2013 Question by: Tim Smith | Product code: 88-3810
Q. Hi there Please can you advise the dimensions of the toroidal transformer model VTX 146 100 212. I.E. outer and inner diameter and thickness. Thanks
A. Hi Tim. Thank you for your question. This product's dimensions are as follows: 91mm outer diameter, 35mm inner diameter and 45mm thick.


12 December 2012 Question by: andrew
Q. what is the transformer regulation?
A. Hi Andrew. Thank you for your question. These are unregulated transformers.


26 November 2012 Question by: tech | Product code: 88-3851
Q. Hello, Could you please tell me what the resistance values are of the primary windings on this transformer, 115v and 230v. I suspect my transformer has fried primaries as the values are very low and the resitance values are almost the same across 110v 220v and 240v. Thanks.
A. Hi Tech. Thank you for your question. Normally you would expect to see something like 1800 ohms between the windings. You simply need to check if the coils are open circuit as this will indicate the wire is damaged


10 June 2012 Question by: Ivan | Product code: 88-3833
Q. How to connect the transformer in the right way? 230 Vac on input side and 18-0-18 Vac on the output side, serie connection Yes, but in the wrong serie you vill blow the thermofuses or get a lot of hum. So how do I do it wright? Best Regards Ivan
A. Hi Ivan, thanks for your question. The wiring diagram is listed in the data sheet to be able to wire this up correctly: https://www.rapidonline.com/pdf/88-3781.pdf


05 December 2011 Question by: Derek Mackenzie | Product code: 88-3826
Q. Presumably for 230V input - I connect grey to violet, blue to neutral, brown to live For 24V output - I connect Yellow to Black, orange is 0V, Red 24V This should then give me 9.38A at 24V
A. Hi Derek Thanks for your question. Our technical department have advised that this is indeed correct.


04 October 2011 Question by: | Product code: 88-3820
Q. Do these come with mounting bolt, dish and washers?
A. Thanks for the enquiry Dean The mounting bolt and the washers are suppilied with these units.


29 August 2011 Question by: watermaid | Product code: 88-3820
Q. Does this range have solated primary and secondary windings? i.e isolating transformer
A. This unit does have primary and secondary winding - but is not considered as an isolating transformer. That is a specialised style
