SDG #207 The New High Precision Riden RD6006P Power Supply from Banggood

The Riden RD6006P is the higher precision sibling of the well known RD6006 programmable buck module, and the main selling point is finer resolution and tighter accuracy rather than more output power. That makes it an interesting proposition for anyone who already owns a standard RD6006 style unit and wonders whether the upgrade is worth the extra money, or for people who want bench supply style resolution without paying laboratory prices.

The review starts with the hardware itself. Pulling the module apart shows how Riden has approached the precision claim: a look over the PCB layout, the switching section and the parts chosen for the measurement and reference chain. The standout component is a Texas Instruments 2.5V voltage reference, which is the sort of part that actually determines whether a stated resolution translates into usable accuracy. Higher grade current sense and divider components matter just as much, because a display that shows extra digits is meaningless if the underlying reference and sense path drift.

Testing then puts those claims under scrutiny, checking how closely set voltage and current track measured reality across the range, and how the readback compares against a reference meter. This is the crucial part for buyers, since the P variant is sold almost entirely on metrology rather than features. Bear in mind that this is a DC to DC converter module, so it still needs a suitable input supply and enclosure, and thermal behaviour and switching noise remain part of the picture.

The closing summary weighs the extra cost against the measured improvement, which is the practical question for anyone deciding between the standard RD6006 and the RD6006P.
