Description
LRS-75 series is a 75W single-output enclosed type power supply with 30mm of
love profile design. Adopting the full range 85-264VAC input, the entire
series provides an output voltage line of 5V, 12V, 15V, 24V, 36V and 48V.
In addition to the high efficiency up to 91.5%, the design of metallic mesh
case enhances the heat dissipation of LRS-75 that the whole series operates
from -30C through 70C under air convection without a fan. Delivering an
extremely low no load power consumption (less than 0.3W), it allows the end
system to easily meet the worldwide energy requirement. LRS-75 has the
complete protection functions and 5G anti- vibration capability; it is
complied with the international safety regulations such as TUV BS
EN/EN62368-1, BS EN/EN60335-1,BS EN/EN61558-1/-2-16, UL62368-1 and GB4943.
LRS-75 series serves as a high price-to-performance power supply solution for
various industrial applications.

SPECIFICATION
NOTE
- All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25C of ambient temperature.
- Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
- Tolerance: includes set up tolerance, line regulation and load regulation.
- Line regulation is measured from low line to high line at rated load.
- Load regulation is measured from 0% to 100% rated load.
- Length of set up time is measured at cold first start. Turning ONOFF the power supply very quickly may lead to increase of the set up time.
- The ambient temperature derating of 5C/1000m is needed for operating altitude greater than 2000m(6500ft).
- The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by
NOTE mounting the unit on a 360mm 360Omm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies. (as available on http://www.meanwell.com)
