Question by Bob Fisher | Product code: 88-3795
30 July 2015

Q88-3795 Hi, my question is in two parts. a) Are all four windings protected from o/load by an internal trip device? b) Is that internal trip self re-setting or not? Thanks Bob
AHi Bob, thank you for your question. This has an internal thermal fuse that is non resettable. This blows if the core temperature reaches a temperature that would cause a fire. Any other protection such as fuses will need to be added to your design.

QDo these transformers come with a fixing kit?
AHi Ian. Thank you for your question. The fixing kit is included.

QItem 88-3801 VTX-146-060-215 does not seem to be included in the PDF file from manufacturer. Have you the dimensions pleaee?
AHi 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.

QHi 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
AHi Tim. Thank you for your question. This product's dimensions are as follows: 91mm outer diameter, 35mm inner diameter and 45mm thick.

Qwhat is the transformer regulation?
AHi Andrew. Thank you for your question. These are unregulated transformers.

Question by tech | Product code: 88-3851
26 November 2012

QHello, 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.
AHi 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

Question by Ivan | Product code: 88-3833
11 June 2012

QHow 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
AHi 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

Question by Derek Mackenzie | Product code: 88-3826
06 December 2011

QPresumably 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
AHi Derek Thanks for your question. Our technical department have advised that this is indeed correct.

Question by | Product code: 88-3820
07 October 2011

QDo these come with mounting bolt, dish and washers?
AThanks for the enquiry Dean The mounting bolt and the washers are suppilied with these units.

Question by watermaid | Product code: 88-3820
30 August 2011

QDoes this range have solated primary and secondary windings? i.e isolating transformer
AThis unit does have primary and secondary winding - but is not considered as an isolating transformer. That is a specialised style

The transformer is heavily built and therefore a weighty item, always a good sign of quality with a transformer. When compared with other companies, this was excellent value for money. I have not as yet tested the transformer as it is part of an ongoing hi-fi amplifier project but I have every confidence it will prove to work very well.

These transformers are excellent value for money. I bought one to fix an audio amplifier - 160VA 2x25V - and it worked great. The output voltage was quite stable, if a little higher than specified (around 27-28 volts measured with my true RMS meter). It came with a mounting kit including a nut and bolt (about 5mm diameter with 10mm hexagonal head), two pieces of foam to sandwich the tranny, presumably to damp vibrations, a metal plate to go on top, two normal washers and a springy washer. It came with no instructions but I guessed that you were supposed to put the bolt with a washer through the case, then a piece of foam, then the transformer, another piece of foam, the metal ring, the springy washer and then the nut. That leaves one washer unused, so Ive probably done something wrong but it seems to hold.
