■ Description
LRS-75 series is a 75W single-output enclosed type power supply with 30mm of
low 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 -30°C through 70°C 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.

PACKING|  0.25Kg ; 45pcs/ 12.25Kg/ 0.77CUFT
NOTE|  1. All parameters NOT specially mentioned are measured at 230VAC
input, rated load and 25℃ of ambient temperature.
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted
pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
3. Tolerance : includes set up tolerance, line regulation and load
regulation.
4. Line regulation is measured from low line to high line at rated load.
5. Load regulation is measured from 0% to 100% rated load.
6. Length of set up time is measured at cold first start. Turning ON/OFF the
power supply very quickly may lead to increase of the set up time.
7. The ambient temperature derating of 5℃/1000m is needed for operating
altitude greater than 2000m(6500ft).
8. The power supply is considered a component which will be installed into a
final equipment. All the EMC tests are been executed by mounting the unit on a
360mm*360mm 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.”
