Value for money transformers - Zorro



Proudly presenting... 

Value for money power transformers - Zorro Transformers

In this turbulent times, where times are bad, jobs are scarce, pay increment is puny, bonus is shaky, funds for leisure or pleasure will be eliminated or reduced significantly. We totally understand, and therefore, we introduce this super value for money transformers for the sake of all the DIYers out there.

These will be considered as our Level 0 products. They are better than your run of the mill, of the shelf transformers with those shiny low grade cores. Of course, they still cannot compete with our Level 1 and above transformers. Still, they are made with very decent materials and can be considered as audio grade transformers.

Features

- DuPont high temp bobbin
- 0.75mm copper foil electrostatic shield / ground
- Single or dual primaries allowed
- Secondaries - 4 sets only, 5 sets (depends on complexity) for higher power version 
- Higher power / higher voltage - please email us  
- Add at least 15-20% of VA reserve to cater for losses and lower temp operation 

Transformer Ordering Notes, due to power factor considerations:

  • For high voltage B+
    • Apply at least 1.5x (150%) of intended load
    • 2x is recommended for high fever audiophile use
    • Say 200mA DC is required, assume 300mA minimum when multiplying with the AC voltage for VA calculation.
  • For low voltage DC filament supply
    • Apply at least 2x (200%) of intended load
    • 3x is recommended for high fever audiophile use
    • Say 3A DC is required, assume 6A minimum when multiplying with the AC voltage for VA calculation.

Zorro Transformers Purchasing Tips:

  • Purchase more units to lower down the shipping charges
  • Economical express shipping for Singapore, Malaysia, Hong Kong and China
  • EMS for all other countries - fast, safe and efficient, slightly pricey but worth it
  • Items will be shipped from Shenzhen, China warehouse
  • Payment - pay for transformer costs first, and then pay actual shipping when orders are ready to ship.







 

History 

In order to lower the cost of Zorro transformers to such level, we have to move the Zorro transformer manufacturing to China, subcontract it to a big transformer factory to mass produce it for us in batches. In order to maintain the quality, we do not simply use any factory but one with the technical capability and quality.

  • Experienced contract manufacturer transformers used in home, telecommunications, mechanical, industrial electronics and electrical appliances. 
  • Manufactured by technicians with over >10 years of experience
  • Manufactured using automatic winding machine, with high torque automatic alignment machine and automatic lamination insertion machine
  • Equipped with various electrical measurement equipment to ensure product meeting specifications and quality
  • Equipped with vacuum impregnation machine and automatic controlled temperature oven for baking transformers
  • Stocked various high temp bobbin and various casing for EI41 to EI133 sizes, with H50, H14, Z11 and various other transformers cores. 
  • Guaranteed pure copper magnetic wires are used. All comes with 1 year warranty.
Enjoy!
