The Mean Well LRS-100-24 is a single output enclosed switching AC-to-DC power supply that provides 24V @ 4.5A.
- Mean Well LRS-100-24 Power Supply
KEY FEATURES OF MEAN WELL LRS-100-24 POWER SUPPLY:
- Fully enclosed, convection cooled
- Single 24V output adjustable between 21.6 to 28.8V
- 4.5A current / 108W total power with good regulation
- Screw terminal block connections
- High quality, UL approve
The LRS-100-24 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.
The power supply is preset for a nominal 24V output.
A small voltage adjustment potentiometer +V ADJ near the power LED can be used to adjust the output voltage over the range of 21.6V to 28.8V if desired. This can be useful when compensating for a voltage drop when using long power leads.
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.
- L = AC Line (hot)
- N = AC Neutral
- Gnd Symbol = AC / Chassis Ground
- -V = Ground (x2)
- +V = 24V output (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.
