DH-801 Electronic load

<< < (2/2)

5U4GB:
By coincidence my new high-tech electronic load also just arrived.  Based on this post about a (relatively) cheap electronic load that injected a large amount of noise back into the power line which made power supply noise measurements difficult, I thought I'd go for the latest high-tech linear ohms-law-based purely resistive load, complete with current limiting (I glued a plastic tab over the track so you can never take the resistance below a few ohms), full programmability (via the person turning the dial), and good precision (once I mark the various resistance values on it):

Gertjan:
Hi flash2b,

Congrats! :)  Very small indeed.

Is your DH-801 remote controllable? On the website of the manufacturer are only vague hints to RS-232...
So, connectors on the back panel? Supplied software?

regards, Gertjan.

flash2b:
The one I bought is without the RS232, since KeLian Electrical Instruments Store only had that one. In the manual there is nothing mentioned about SCPI, only a mentioned that RS232 is optional. My hope is that the unit can be easily fitted with a TTL to USB serial converter but that I will see after opening it.  8)

Hm using with a non-hacked DP900

Did you manage to look inside it? I'm really wondering if it has more than a TO220 transistor dissipating the heat.
