Default Re: Does anyone have a ZD-939L that they do not use any more


I have used this unit and like the setup except for one thing

When you turn the power off to the controller it runs the pump for about 3 minuets for the heater to cool down which is fine

But it has the same problem as the another unit made by the same company and that is that the lowest temperature is 320*F which is a little bit of a problem when I just want to dry a board after using flux remover

So I am going to put a small switch on the optic sensor to manually control the temperature when I need to this
9 PC LCD Monitor
6 LCD Flat Screen TV
30 Desk Top Switching Power Supply
10 Desk Top Power Supply
10 Battery Charger Switching Power Supply for Power Tool
6 18v Lithium Battery Power Boards for Tool Battery Packs
1 XBox 360 Switching Power Supply and M Board
25 Servo Drives 220/460 3 Phase
6 De-soldering Station Switching Power Supply 1 Power Supply
1 Dell Mother Board
15 Computer Power Supply
1 HP Printer Supply & Control Board * lighting finished it *

These two repairs where found with a ESR meter...> Temp at 50*F then at 90*F the ESR reading more than 10%

1 Over Head Crane Current Sensing Board
2 Hem Saw Computer Stack Board

All of these had CAPs POOF
All of the mosfet that are taken out by bad caps
