Single Output DC Power Supplies by BK Precision available from Lashen Electronics

TIA568 Wiring Standards

How to decide which wiring pattern to use:

1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.

If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

Model 1744A 0-35 VDC, 0-10A, DC Power Supply

B&K Model 1744A 0-35 VDC, 0-10A, DC Power Supply

Model 1744A Manual

B+K Precision's model 1744 is a 0 to 35V, 0 to 10A DC Power Supply. This power supply has all of the great features you would expect B+K Precision power supplies to have, and some new features not normally seen on power supplies in this price range, these features include an output On/Off button and an output shorting button. The On/Off button allows the user to turn off power to the output terminals without powering down the power supply. The output-shorting button allows the user to short the output terminals to set the current limit.
