One day, after seeing Dave and Todd videos blog about isolation transformer, I started the construction of DIY isolation transformer. Designing wide band rf transformers. Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in sensitive devices, or to. you can put the secondary on both sides of the primary to reduce the leakage inductance a bit. We manufacture transformers, inverters, power supplies, single to three phase converters, variacs and custom designed transformers. Class II transformers have a maximum VA (Volt-Ampere) rating of less than 100 and a maximum secondary output of 30 VAC.
