HARBUCH ELECTRONICS - Toroidal Power Transformer
Made in Australia (Sydney)
I suspect Harbuch is going through a period of "transition" as their website appears to be only partially active and I read somewhere that the original owner (Rod) was retiring
Model: ANTRIM J2415
625VA Total power output capable
Label on one side of the core reads:
HARBUCH ELECTRONICS PTY LTD
Safety Approvals
AS3108-1994 CS/776/Q
EN60742 919691
HARBUCH ELECTRONIC PTY LTD
ANTRIM J2415 625VA
PRI-240 ORG-ORG
SEC1 22V/14.2A RED-YLW
SEC2 22/14.2A BLU-GRY
(Old Australian Made "Boomerang" graphic sticker to the right side)
QUAD (Fully isolated) secondaries:
22V @ 150VA (around 7A full load) EACH Secondary winding
NOT "POTTED" the centre of the donut has no filler AND ...
NO mounting hardware supplied (rubber or plastic discs, metal disc and central bolt)
This transformer was intended for production (power supplies) and the mounting hardware were stored separately from the transformer. I have found SOME mounting hardware but none that directly suit this transformer. As I find more components, I update the availability of the hardware and you could click HERE to see what I have at the moment.
PHYSICAL DIMENSIONS:
145mm diameter
40mm ID donut hole (NO filling)
70mm height
All primary & secondary flying leads 200mm length
All leads are solid core, pvc insulation.
WEIGHT:
5.5Kg !!! It's a heavy beast!
COSMETIC CONDITION:
BRAND NEW
Old Stock
TESTING:
To confirm the transformer is functioning properly, I have made some simple "open circuit/no load" tests ON EACH secondary winding
ALL Secondaries measure 22.9V AC output (4)
EACH IS ISOLATED FROM ANY OTHER WINDING
This provides great flexibility in achieving the desired output voltage e.g connecting ALL windings in series will result in 88V AC ouput (at 7A maximum) or connecting two pairs of windings in series will give you a 44V + 44V AC output or if current is your "thing", connecting all four secondaries in parallel (and of course in phase) will provide 22V AC @ around 25 - 28 Amp capability
Of course any interconnecting of the windings such as the examples above MUST be made in phase!
PRICING: I am a bit "out of touch" with current market prices but I know we paid around my asking price for this type of transformer years ago (wholesale). I see the current prices from reputable distributors is somewhere between A$175 ~ A$300 so my price still represents a significant saving for such an excellent quality, Australian designed and manufactured transformer.
