Single output switching AC-to-DC power supply provides 5V @ 18A.

DESCRIPTION

The Mean Well LRS-100-5 is a single output enclosed switching AC-to-DC power supply that provides 5V @ 18A.

PACKAGE INCLUDES:

• Mean Well LRS-100-5 Power Supply

KEY FEATURES OF MEAN WELL LRS-100-5 POWER SUPPLY:

• Fully enclosed, convection cooled
• Single 5V output adjustable between 4.5 to 5.5V
• 18A current / 90W total power with good regulation
• Screw terminal block connections
• High quality, UL approve

The LRS-100-5 power supply is fully enclosed in a metal enclosure and is convection cooled, so there is no fan to attract dust, make noise or fail. There is a green LED power indicator when AC power is applied.

Voltage Adjustment

The power supply is preset for a nominal 5V output.

A small voltage adjustment potentiometer +V ADJ near the power LED can be used to adjust the output voltage over the range of 4.5V to 5.5V if desired.  This can be useful when compensating for a voltage drop when using long power leads.

Module Connections

Connections are made using 8mm wide screw terminals.  The positive and negative connections come out to 2 terminals each which is handy for connecting up multiple loads.

You may want to pick up one of our AC to spade terminal power cables below to go with this supply for easy hookup.

Terminal Strip

• L = AC Line (hot)
• N = AC Neutral
• Gnd Symbol = AC / Chassis Ground
• +V = 5V output (x2)
• -V = Ground (x2)

There are 2 mounting holes accessible from the top of the unit for permanently mounting the unit if desired.  There are also 2 M3 PEMs on the bottom and 3 on one of the sides which can be used for mounting as well.

OUR EVALUATION RESULTS:

Mean Well power supplies are good quality robust units offered at a fair price.  They are probably the best price / performance value power supplies available and they are fully UL and CE safety certified.

The ventilated enclosure allows for good convection cooling and provide a little more safety margin than when using open frame supplies.  When we have tested these to full rated power, the supplies are running very comfortably.
