Linear power supply unit

This linear power supply provides excellent performance and enables a high-quality power supply for the HiFi system, thereby improving the sound reproduction quality. The fact that the P50 has 2 5 Volt USB-A outputs and a standard 5.5/2.1 mm DC socket, 15 Volt output enables a variety of uses, so it can serve several devices at the same time.

The P50 can be connected to a variety of devices, since 15V and 5V power supply voltages are very common for HiFi devices. An ideal choice for several Topping products, such as powering the DX3 Pro, D50s, A50.

The P50 power supply component is built into a precision-machined, robust, single-block, precision CNC-machined aluminum housing for better mechanical and electromagnetic protection.

The power supply is compatible with 220-240 Volts 50/60Hz, but also with 100-120V 50/60Hz network voltages, so it can be used anywhere in the world. The input voltage is selected with a 230V/115V switch.

The P50 uses a high quality toroidal transformer which ensures low magnetic loss, electromagnetic interference and very low noise to ensure the cleanest possible power supply. The 15 Volt power supply circuit works with a 10000µF, the 5 Volt circuit 8000µF buffer capacitor group, which results in a significant energy reserve to ensure a stable output current.

The P50 uses 3 ultra-low noise TPS7A4700 controllers. These chips are capable of high precision, making them perfect for HiFi use and an excellent choice for analog circuits.
