TOPPING P50 Linear Power Supply Black

The P50 is a linear power supply from TOPPING designed to deliver clean, high-quality power to your HiFi system, helping to improve sound reproduction. It offers two 5-volt USB-A outputs and one 15-volt output on a standard 5.5/2.1 mm DC jack, so several devices can be powered at the same time. Both 15 V and 5 V are very common requirements in HiFi equipment, which makes the P50 suitable for a range of components, including Topping's DX3 Pro, D50s and A50.

The unit is housed in a robust aluminium enclosure machined by precision CNC from a single metal block, providing mechanical and electromagnetic shielding. Inside, a toroidal transformer keeps magnetic losses, electromagnetic interference and noise very low. Puffer capacitors of 10,000 µF for the 15 V circuit and 8,000 µF for the 5 V circuit add energy reserves for a stable output current, and three ultra-low-noise TPS7A4700 regulators are used for high precision in analogue circuits.

The power supply accepts 220–240 V and 100–120 V at 50/60 Hz, and the input voltage is selected with a 230 V/115 V switch.
