AC Step Down Transformers
Standard AC step down isolation transformers to convert Mains Voltages to the lower voltages required by linear amplifiers are available. Varedan supplies both single phase and three phase transformers. Single phase transformers are available at 1 and 2 KVA. Three phase transformers are available at 3, 6 and 9 KVA.
