Check the listing for details. 1pc EMI 25W Adjustable Voltage Regulator Talema Linear Power Supply Dualer LM317. Color: --, Condition: New. Listed at 52.25 USD. 1pc Dual LM317 25W Voltage Regulator Board Mountable Talema Linear Power Supply EMI Dual LM317 15W Two Transformer Outputs Adjustable Voltage Regulator PCB Mountable Talema Linear Power EMI Blue Customized Yew Wah Sealed Ring Cow! input voltage 220. output voltage adjustable! Output voltage adjustable! You can note the output voltage you need! Dual 2.5V - dual 18V, especially added to the EMI anti-interference filtering function, so that precision instruments lower interference, if the audio system, the music texture is stronger. Material is also a luxury version, capacitors using ELNA audio special capacitors, German red WIMA, and with high-speed diodes instead of cheap rectifier bridge stack, integrated design ideas! All imported audiophile capacitors and voltage regulator, integrated design, so that the power supply part is completely independent, better anti-interference ability, suitable for preamplifier and other lines. Parameters: PCB size: 146X62MM Input voltage: AC 210-240V (standard 220V) Output voltage: positive 2.5V to positive 24V stepless adjustable The transformer we send by default is adjustable between 12-18V, maximum 18V. If you need other voltage, such as 24V (please note that the voltage difference will be very large), please leave a message on the order, thank you! Regulator core: imported ON LM317 Double-sided immersed gold PCB, ground line optimization design, to ensure the ripple and eliminate interference loop.
