New Cartveyor replaces old Shopping Cart Conveyor - PFlow









http://www.cartveyor.com



Cartveyor™ Shopping Cart Conveyor is easy to use and can run parallel with a passenger escalator or as a stand alone unit. Also referred to as trolley conveyors or buggy conveyors in different countries, these shopping cart conveyors are extremely advantageous in multi-level retail stores. Cartveyor incorporates many safety features, requires minimal maintenance and is designed for years of trouble-free performance. Cartveyor is made by Pflow Industries, Inc. – a U.S. based leading supplier of vertical conveying equipment for more that 30 years.

IGBT IPM Intelligent Power Module Diode and Junction Test Procedure using a DMM.

Single Pack IPM IGBT Powerex PM600HSA120 & similar Intellimod IGBT Bricks:
Meter on Diode Test Mode
BLK to C, Red to E = 0.5v +/-, swap = OL
Meter on Resistance Mode (Ohms)
E to Pin 4 = 0 Ohms

Dual Pack IPM IGBT Powerex PM300DSA120, PM200DSA120 & similar Intellimod IGBT Bricks:
Meter on Diode Test Mode
BLK to C1, Red to E1 = 0.5v +/-, swap = OL
BLK to C2, Red to E2 = 0.5v +/-, swap = OL
Meter on Resistance Mode (Ohms)
E1 to Pin 4 “P” = 0 Ohms, E2 to Pin 4 “N” = 0 Ohms

6 Pack IPM IGBT Powerex PM150CVA120 & similar Intellimod IGBT Bricks:
Meter on Diode Test Mode
BLK to P, Red to W = 0.5v +/-
BLK to P, Red to V = 0.5v +/-
BLK to P, Red to U = 0.5v +/-
Swap Leads = OL
BLK to W, Red to N = 0.5v +/-
BLK to V, Red to N = 0.5v +/-
BLK to U, Red to N = 0.5v +/-
Swap Leads = OL
Meter on Resistance Mode (Ohms)
W to Pin 2 = 0 Ohms
V to Pin 6 = 0 Ohms
U to Pin 10 = 0 Ohms
N to Pin 15 = 0 Ohms

*Note: Testing the Diode portion of a 6 Pack IGBT is the same as testing a 3 phase rectifier.

If using Resistance Mode (Ohms) to test the Freewheel Diodes you should read over 100k (100,000) Ohms one way and read Open OL when you swap meter leads.



Any shorts or opens on diodes or opens on gates indicates a defective IGBT.

Building a Magnetic Laptop Shelf - Simple Inexpensive DIY (V1R1)









Building a Magnetic Laptop Shelf - Simple Inexpensive DIY (V1R1) 

Building a simple inexpensive portable DIY magnetic laptop computer shelf.
This prototype magnetic shelf was designed to be light and compact for easy transport for field use.
This is one of three designs I plan to build. This was the simplest, fastest and least expensive to build but my least favorite design.
Don’t hold your breath on the other two models, I started to build one of these back in June of 2000. I procrastinate!

The holes were cut only to lighten the weight.
The laptop with cables just barely fit on the shelf and 1” deeper and wider would be better.
Note holes on right side for screwdrivers etc. 

DIY Laptop Shelf Materials List:
Paracord,
Cutting Boards,
Hard Drive Magnets,
Piano Hinge,
Silicon Glue,

*Cup magnets would be a better alternative than hard drive magnets and easier to mount but I have an excess of hard drive magnets and this is just the first prototype.  The final version will have cup magnets.

Tools List:
Drill,
Drill Bits,
Hole Saw,
Dremel Circular Saw with plastic cutting blade.

Only tools necessary are the drill and drill bits. The rest are optional to lighten the weight.
