UDP-203 Digital Silver-plated Linear Power Supply For OPPO Player PSU Modified

Description: Introduction: This is a specifically for the model for OPPO player UDP-203 4K UHD HDR development of linear power board modified/upgrade module. It can directly replace original OPPO player UDP-203 4K UHD HDR Power supply board. Before buying it, Please check to check your power supply model. A low-pass filter (with a corner frequency of 1.6Hz) prevents zener noise from being 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 pass transistors, The high current rating provides a very high safety headroom against overcurrent damage. The negative temperature coefficient of MOSFETs prevents damaging thermal-runaway conditions that may plague conventional BJT devices. ◆ Digital circuit power supply. ◆ All-discrete topology. ◆ Series regulator design. ◆ No IC (integrated circuits) are used. ◆ Low noise, high PSRR. ◆ Use 50VA Customized secondary Silver-plated Toroidal transformer, can provide powerful energy supply. ◆ Use audio HIFI dedicated capacitors. ◆ Using 4mm aluminum plate, can provide firm installation and sufficient heat dissipation. Input voltage: AC 115V or 230V (optional) Tips: ● Do not short the output terminal to discharge capacitor, otherwise it will damage the power board. ● This version is digital version. After using this version, the analog decoding part built in OPPO player UDP-203 4K UHD HDROPPO player UDP-203 4K UHD HDR will not be able to use. Please pay attention to whether the AV amplifier has multi-channel decoding function. Packaging includes: UDP-203 HIFI Digital Silver-plated version Linear power supply X1 NOTE: We do not provide any cables. If you need to upgrade the cables, please go to my store to purchase.
