• Power supply 30V.
• Box for product Part #FB06

Variable Regulator Kit 0 - 30V, 3A Comes complete with heatsink, all necessary components and circuit board. In order to insure reliable, stable operation, it would be best to use a transformer capable of delivering up to 4 Amps. If your current demand is less, you could get by with a smaller transformer as long as it exceeds your current requirements. Assembly is required!

Key Features:

• This regulator circuit is high efficiency because of IC regulator UA 723.
• It is designed to prevent over power supply maximum to 3A. so it requires transformer 4A with 12 - 0 - 12 pole ,if lesser than 12V.
• Power supply 30 V.
• Box for product Part #FB06
