Any interest in High-power ETD54 transformers? (1:25 step-up) — FREE for hobbyists/makers! (Just cover shipping)
Hey everyone,
I have a tray of unused MagTop MTETD54-4TS high-frequency transformers sitting around and would love to get them into the hands of hobbyists, builders, or researchers who can actually put them to work!
Quick Specs
Core: ETD54 (PC40 ferrite) — capable of high power throughput.
Turns Ratio: 4 : 100 (1:25 step-up).
Primary Winding: 4 turns made of 0.35 \ 30mm copper foil (rated for very high continuous DC input current).
Secondary Winding: 100 turns, 2.5kV AC isolation primary-to-secondary rating.
Inductance: 7.0uH@ 10kHz.
Weight: ~300g / 0.65lbs each.

What These Are Great For:
High-power 12V/24V to high-voltage DC inverters (300V+ bus generation)
High-current ZVS driver setups / Plasma arc generators
Capacitor chargers for coilguns, railguns, or pulse discharge experiments
Details & Logistics
Location: Shipping from California, USA.
Cost: FREE! You just cover the actual shipping cost.
Weight/Shipping Calc: Each unit weighs roughly 300g - 0.65lbs, so single or small-qty shipments should easily fit into USPS Ground Advantage or small Flat Rate boxes.
