What Is a Power Supply
Overview
- Power supplies are essential links in supplying energy to control systems. They are the heart of every
control cabinet.
- Modern industrial automation applications require safe, efficient, packaged AC/DC power supplies to
support DC voltage and current to the control systems used in factory automation and process control.
- Power supplies are complimentary products to Weidmuller’s line-up of both active and passive products.
Protecting 24VDC Circuits
 Circuit Breakers
 Fuses
 Electronic Circuit Protection
 Nothing
Circuit Breaker
201 series thermo-magnetic circuit
breaker trip curve….
 May take 5-10 times the rated load
to shut down or trip.
 Allows power supply to sag and stop
supplying power to every circuit.
 Typically Over-Sized (80-125V).
 Susceptible to Nuisance tripping
due to in-rush currents.
Fuses
 Drastically affected by ambient temperature
- Hot Temperatures – lower current needed to open.
- Cold Temperatures – higher current needed to open.
 No ability to reset
 Typically requires 5X the current to open
- Switch mode power supplies cannot provide sufficient current.
- Voltage level will drop off before the fuse opens.

switch mode power supply
Electronic Circuit Protection
 Will open current path before voltage sag
 Isolation of circuit failures
 Control Cabinet not affected by one failure
 Status and Signal output is available
 Visual Indication of failures
 Ability for remote reset
 Orientation doesn’t matter

The Competition
Competition (ESX10-T Series)
 Siemens Sitop Select (Fuse)
-
Risk of incorrect current rating adjustment
Shuts down when voltage drops below 18V
Mechanical reset necessary after shut down
Have to reset all four channels at once
Complex handling and can loose fuses
Not easy to identify problems
Risk of destruction if fuse is re-inserted
without failure remedy.
- Only Available as a 4-way module
Competition (ESX10-T Series)
 Murrelektronik MICO 4.x (Fuse)
-
No physical Isolation with disconnection
No real current limitation
Difficult to wire on DIN rail
Remote reset is possible and wired separate
Functions only compatible with MURR Systems
Only a 3-way unit with ratings up to 10A
Extended voltage interruptions lead to shut down
Adjustable current ratings leads to disconnect
Trip behavior depends on cables used
Key Questions
 How do you currently power active devices and electronics in your automation control
panels?
 Do you use switch mode 24VDC power supplies for equipment in your panels and
machines?
 Are you protecting your critical loads, such as PLCs and Ethernet switches, from,
power supply failures? If so, how?
 Are you satisfied with the time it takes to identify and troubleshoot power-related
failures in your controls panels?
 Are you satisfied with the reliability of your DC power sources?
