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 antivibration 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 GB 4943.1.
LRS-75 series serves as a high price-to-performance power supply solution for
various industrial applications.

NOTE|
-
All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25’C 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 vp 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 Ot,t,OFF the power supply very quickly may lead to increase of the set up time.
-
The ambient temperature derating of 5’C/1000m Is needed for operating alt ltude 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 mounting the unit on a 360mm’360mm metal plate with 1 mm 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.”
