The Mean Well LRS-200-12 is a single output enclosed switching AC-to-DC power supply that provides 12V @ 17A.
- Mean Well LRS-200-12 Power Supply
KEY FEATURES OF MEAN WELL LRS-200-12 POWER SUPPLY:
- Fully enclosed, convection cooled
- Single 12V output adjustable between 10.8 to 13.2V
- 17A current / 204W total power with good regulation
- Screw terminal block connections
- AC Input Voltage Selector switch
- High quality, UL approve
The LRS-200-12 power supply is fully enclosed in an 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.
Note before first using the power supply:
There is a red AC Input Selector Switch on the side of the module for selecting the input AC voltage (115 / 230V) that the module will be powered from. Verify that this is set to your voltage before power is applied. We preset this to 115V which is what most customers will use.
The power supply is preset for a nominal 12V output.
A small voltage adjustment potentiometer +V ADJ near the power LED can be used to adjust the output voltage over the range of 10.2V to 13.8V if desired. This can be useful when simulating a lead-acid battery voltage or 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 3 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.
- +V = 12V output (x3)
- -V = Ground (x3)
- Gnd Symbol = AC / Chassis Ground
- N = AC Neutral
- L = AC Line (hot)
There are four M4 PEMs on the bottom and 2 on each side which can be used for mounting.
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.
- This power supply has an AC input voltage selection switch. Be sure to select the correct voltage, either 115V or 230V, for your application or damage may result.
