250W toroidal transformer 220V to dual 12V15V18V24V28V30V power amplifier transformer audio power supply can be customized voltage
Customers who purchase, please note the required output voltage and multiple sets of voltage outputs on the order. Or contact customer service!
Voltage specifications can be customized according to customer requirements, or multiple sets of voltage outputs can be customized.
Parameters to provide: input voltage, output voltage, power, size (diameter and height)
and other specific information. The output is in multiple groups, and each group of current, voltage or power, external
size and other requirements. The rough algorithm of power is (voltage x current = power), and more
The number of groups can also be calculated according to this. If you need multiple groups of voltages, you can determine the price with customer service. custom made
Please consult customer service for price and delivery time.
The power marked by this shop is rated power, non-peak power! Peak power, peak output refers to the instantaneous power of the transformer, not the power that can be loaded for a long time. Buyers and friends please pay attention
Distinguish the difference between rated power and peak power!
Commitment to customers: The transformers made by our factory are pure copper transformers made of oxygen-free pure copper wires
(do not do aluminum wire or copper clad aluminum, guarantee pure copper, fake one loses ten) factory direct sales, guarantee
Prove enough power.
