Building a Bench Power Supply with the RD6006

I decided to finally upgrade the old home-made switching power supply I've been using for the last 20 years (at some point it becomes more of a fire hazard then a power supply).  Luckily components are a little more readily available these days, and I chose the Riden RD6006 controller.  You can find the components more reasonably priced here (if you can wait a month for shipping):

RD Riden Factory Store

or pickup the components on Amazon (a fairly steep markup, but it will be at your house tomorrow):

60V Power Supply

Case

CR1220 Battery

PC Power Cord

After unboxing and testing the power supply with a test cable, the power supply was ready to assemble:

First install the switch, power terminal, and case fan:


Mount the power supply:


Add the case feet (so the supply screws don't scratch up your desktop):

Wiring took a little bit to figure out; the marking is camouflaged fairly well, but if you look closely you can see an E (for earth ground) and N for neutral (leaving the last terminal being hot):

The jumper cables from the kit were sized correctly:


Next install the case fan temperature controller:


And wire directly to the supply:


The power terminal was pulled from the controller and wires added from the case kit:


Power cable connected to the controller (making sure to honor polarity on the PCB):


Add a CR1220 battery as the mount is beneath the WIFI module:



Install the WIFI module:


Add the controller temperature probe:


Before closing up the case, power it up and make sure all is well:


A project is never done until the wire wraps go on...



Fully assemble the case:


Note that I had a bit of trouble getting all the parts together - the controller JUST fits within the case, and the case is not 100% square, so there was one case screw I just could not get aligned.  All that being said, I'm fairly pleased with the result.

The manual can be found here from the vendor:
