Modular Power Supplies FAQ
Select question from the list below or return to faq categories.
-
What is the difference between a modular power supply and a configurable one?
TDK-Lambda differentiates between 'modulars' and 'configurables’. ‘Configurables’ are configured ‘on board’ with discrete components – while ‘modulars’ are configured using modules.
-
What is a modular power supply?
A Modular Power Supply is one that is assembled (configured) using a variety of pre-built building blocks (modules).
-
Is it complicated to select the right version for my application?
It is actually very simple. TDK-Lambda's Quick Product Finder will guide you through the steps
-
What is the minimum quantity I have to buy?
There is no minimum order quantity for most of our power supplies.
-
How long does it take to get all the safety approvals?
All of our modular power supplies will be supplied with all of the safety certifications. This covers all potential configurations so you can be sure that this is covered.
-
How soon can I get a unit?
Because the modular units use pre-built assemblies, lead-time can be as short as 48 hours. Most modular power supply manufacturers, including TDK-Lambda, offer a quick-turn service and also have well-established VAR (Value Added Reseller) networks.
-
Are these units expensive?
Not really. Prices have dropped substantially since 1980 when TDK-Lambda first introduced modular supplies. They can be very cost-effective in quantities from 1 to 5000 or more units/year.
-
Why should I use a modular over a modified standard or custom?
As these modular products are sold to a huge number of different customers, who are using them over a wide range of applications, they are field proven. With a custom or modified standard that risk goes up dramatically as you will be the "beta" site.
-
Can I get odd output voltages?
Yes, many output "modules" feature a wide adjustment range, often 2:1. Recently, we had a customer ask for five (5) floating 18V outputs and we were able to meet their needs with a modular power supply.
-
How many outputs can I get?
Our MU6 range offers up to 13 outputs.
