OPPO Upgrade KIT Project

To complete this project, you need to have superb electronics knowledge and a certain amount of DIY ability.Due to time zone and language communication restrictions, we can only provide limited technical support, and you need to solve probl by yours. We do not provide information other than the product introduction page.

MOFI-MOD OPPO UDP-203 Fully Discrete Linear Power Supply Upgrade Kit （Standard Edition）Project

Dial circuit power supply:All-discrete topologySeries regulator design.No IC (integrated circuits) are used.Low noise, high PSRRA low-pa filter (with a corner frequency of 1.6Hz) prevents zener noise from g introduced into the error amplifier.The error amplifier is a discrete implementation of an opamp with a high open-loop gain of 102.5dB.A long-tailed pair differential amplifier with current mirror and constant current source forms the first stage of the error amplifier. The second stage is the voltage amplification stage (VAS), also with constant current source load. The 3rd stage is comprised of the power MOSFET output devices configured as a source follower.High-current MOSFET pa nsistors.The high current rating provides a very high safety headroom against overcurrent damage.The negative temperature coefficient of MOSFETs prevents dam thermal-runaway conditions that may plague conventional BJT devices.multi- function power supply：

Use ST LM7815/LM7915Other：Use 50VA nsformer, can provide powerful energy supply.Use audio dedicated s.Using 4MM aluminum plate, can provide firm installation and sufficient heat diipation.Use gold-plated socket/componentsDo not short the output terminal to discharge , otherwise it will damage the power board.

Product configuration

After the upgrade module, we have tested the key point voltage, and employ the electronic load meter and the oscilloscope for double testing.OPPO UDP-203 Standard Edition Linear Power Supply Module 1PCSDoes not provide any wiresOur shop provides hiend cables for you to buyTIPS:The module supports OPPO UDP-203 multi- output.
