Regulated Power Supply 12 Volt 1.25 Amp
PWR12$24.00
Clean Power is Essential
Good clean power essential for the operation of the board. For the switching of the relays and more importantly powering the firmware that processes the commands. Without it, the board can become unreliable.

PWR12 Power Supply
Applying
Good clean power to the board in essential for the operation of the board. Not only for the switching of
the relays but the firmware that processes the commands. Without good steady clean power from a regulated power
supply the board simply will not function correctly. More that one troubleshooting question has turned out to be
from someone who says they are using a power supply that they had "just laying around" and it was not
sufficient enough to provide the power needed to operate the board. We also carry an international power supply
with interchangeable adapters for international customers.
Triad Quality & Reliability
The WSs surface mount construction with automated assembly delivers higher quality and reliability. The result is a dependable power supply offering longer life at a lower cost of ownership. The WS series also offers class B EMI certification with excellent power isolation, filtering out noise and providing common mode signal rejection.Power Requirements
All boards on the site require 12 VDC power. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm R/A barrel connector.RoHS Compliant
This
power supply is led free and RoHS Compliant. If your requirements are for RoHS compliant parts this power supply is manufactured with RoHS compliant
led free parts and solder.
Sharing Power Supplies w/Inductive Loads
This power supply should not be shared with the board and inductive loads. For instance, you should never use a single power supply to power a board and a 12V DC Motor. Doing so will introduce extremely high-voltage spikes that will damage the logic and power regulation portions of the board, in many cases it will not be repairable and void the warranty. Induction spikes that do not damage the board can interfere with the logic on the board so the firmware cannot process the commands requiring power cycling the board to restore functions.Environmental Specifications
