BRZHIFI SPD-25PRO 25W Linear Power Supply Regulated Power Supply w/ 2" Screen (110V DC12V 2A Output)

BRZHIFI SPD-25PRO 25W Linear Power Supply Regulated Power Supply w/ 2" Screen (110V DC12V 2A Output)

Description:
SPD-25PRO is developed to meet the needs of high-definition audio and video equipment. The low noise linear power supply has low ripple, high speed, and low internal resistance. Its circuit architecture is a UV-level noise DC voltage regulator circuit with precision voltage reference, high-speed op amp and high-power transistors; at the same time, the circuit adds CLC high-current Hifi filter inductor, and the EMI isolation level further improves the quality of the DC power supply! On the other hand, we provide customers with visual current, voltage, and power real-time indication, allowing customers to monitor and fine-tune the output DC voltage in real time. It features a 2-inch high-definition TFT display. This is a visual interface that other companies do not have at present.

Features:
* Low noise linear regulated power supply
* uV-level noise output is as quiet as the deep sea
* Voltage, current, power, and full monitoring interface
* Low noise, high speed, low internal resistance, and output overload protection
* Maximize the potential of your devices: The linear power supply can filter out grid interference, providing clean power that results in a very dark and pure sound foundation. The sound is not thin; instead, it possesses a healthy, full-bodied thickness and a solid feel. Moreover, it ensures more stable power supply and signal transmission for your devices.
* Comprehensive enhancement in sound and picture quality
* More stable data connection with reduced interference
* The key to quality lies in the meticulous selection of components: core materials are sourced from major manufacturers and imported parts. The SPD-25PR0 utilizes a Yaohua sealed transformer from China. The output transistor core supports a maximum current of 10A, and the operational amplifier employs the high-end American OPA1611, with a constant current diode set as the reference. It also features a high-speed filtering Japanese power array and a Sanken rectifier bridge stack from Japan. In terms of sound, performance, and reliability, this power supply stands out among similar power linear power supplies on the market for its exceptional performance and cost-effectiveness. The entire unit is equipped with short-circuit protection, making it safer and more reliable.

More Advantages:
* Large-current rectifier bridge + array filter capacitors
* Two-way CLC filtering for output
* New design and parameter visualization
* Ring-shaped sealed transformer: It has the advantages of small vibration, low magnetic leakage, low power consumption, high efficiency, and good output characteristics.
* Precision reference + high-speed operational amplifier
* 4A EMI filter
* Original high-power transistors

Premium Components:
* High-Current Rectification + Array Filter Capacitors: Original filter capacitors for Rubycon are used. These capacitors feature low impedance, high ripple and long lifespan, making them particularly suitable for electronic circuits that demand high performance and stability.
* 4A EMI Filter: The EMI filter suppresses high-frequency interference. It can mitigate grid noise, high-order harmonics, and noise generated by switching power supplies, motors, and other sources. It improves the purity of audio quality and reduces noise caused by AC power interference.
* Dual CLC Filtering: Used to eliminate high-frequency noise and fluctuations in the circuit, thereby enhancing circuit stability and precision.
* Precision Reference + High-Speed Operational Amplifier: The operational amplifier employs the high-end American OPA1611, with ultra-low distortion (0.000015%). The reference is equipped with a constant current diode, ensuring very low noise.
* Original High-Power Transistor: The output uses a high-power transistor, 2SC5198. With a maximum current of 10A and 100W power, its sufficiently low internal resistance allows it to handle high-current output with ease.
* New Design with Parameter Visualization: A 2-inch TFT HD display provides real-time visualization of current, voltage, and power. It also includes a temperature sensor to monitor internal temperature.
* Luxurious Material Selection: The circuit architecture is inspired by the JUNG SUPER low-noise precision regulator (JSR). With excellent wiring and high-quality linear components, the output precision is extremely high, with low ripple. The actual listening experience surpasses that of most Class A power supplies.
