Power Supplies

By Lab Manager Magazine

Since standard laboratory equipment contains its own individually-designed power supplies that plug into standard electrical outlets, many labs rarely use external power supplies—mostly for specialty applications, instrument testing, and design. OEM power supplies operate steadily and predictably at one output inside equipment, instruments, and computers. By contrast, low- and medium-voltage programmable supplies are designed for applications—particularly in testing, measurement, and instrument design— where users might require 12V one day and 5V the next.

Top 5 Signs that You Should Service or Replace Your Power Supply

Top 6 Questions You Should Ask When Specifying Power Management Solutions

article image What options are available and how will they affect the lab?
article image Will you need to do a complete overhaul each time you add a piece of equipment or are solutions flexible enough to allow for additional equipment? 
article image How difficult is it to move or relocate plugs and receptacles if you need to adjust your layout? 
article image Does the company’s product offer any level of sustainability? 
article image What kind of product life can you expect from the company’s system? Is it durable enough to handle years of use or will it continually show wear? Can you count on the company’s team to provide service throughout the product’s life? 
article image What kind of cost should you expect from the company’s system? Materials? Installation? On-going maintenance? Service? Warranty? Total cost of ownership?
