PW-05 50W Precision Power Supply Linear Regulated Power Supply w/ Green Transformer & 15V 1A Output

PW-05 50W Precision Power Supply Linear Regulated Power Supply w/ Green Transformer & 15V 1A Output

Description:
This newly launched version is an upgraded model. Its USB port provides a fixed 5V output, enhanced with ceramic capacitors for filtering and decoupling.

This power supply utilizes 6 parallel LT3045 voltage regulators and a fully shielded 50W transformer. Compared to ordinary switching power supplies, it delivers significant improvements—blacker background and more transparent sound. It is suitable for power upgrades in Raspberry Pi, DACs, digital interfaces, hard drive enclosures, and media players.

Features:
* The USB port provides a fixed 5V output and is equipped with ceramic capacitors for filtering and decoupling.
* The rectifier uses imported Schottky diodes, and the filter capacitors are high-frequency, high-temperature-resistant capacitors for Panasonic, with a total capacity of 23,100μF.
* The LT3045 is equipped with a heat sink to ensure excellent load performance and prevent overheating.
* A built-in switch allows conversion between 110V and 220V input voltages.

Specifications:
* Input Voltage: 110V/220V
* Output Voltage: 15V
* Static Power Consumption: 0.5W
* Filter Capacitor Capacity: 23100μF, high-frequency low-ESR (high-temperature resistant)
* Transformer: 50W sealed toroidal transformer
* Output Current: DC 1A and USB 1A
* Output Interface Type: USB port + DC 5.5/2.1
* Overheat Protection: With
* Over-current Protection: With
* Output ripple: 20μV (LT3045 version)
* Output Voltage Fine Adjustment: With
* Dimensions: 173 × 140 × 55 mm

Attention:
* Due to the use of imported components in some parts of the machine, supply shortages may occur frequently under the influence of international conditions. Therefore, material or design changes may be made without prior notice.
* The LT3045 uses six chips in parallel for voltage regulation. Under a 2A load, the ripple was measured at 15μV (as of July 2024, measured using an APX555B analyzer).
* The length of the DC power cable and the grounding point of the instrument can have a significant impact on ripple test parameters.
* The USB port and the DC port have different voltage outputs. The USB port outputs a fixed 5V and is not adjustable, while the DC port provides adjustable output voltage.
* Due to the accuracy limitation of the voltmeter, the displayed voltage may fluctuate. This is a normal phenomenon and does not affect functionality. (For example, when the actual voltage fluctuates by 0.01V, the voltmeter may show a change of 0.04V because its display accuracy is 0.04V.)
* When the connected device draws high current, it is recommended to slightly increase the output voltage of the power supply to compensate for voltage drop in the power cable.
