Description

LRS-35 series is a 35W 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 of up to 89%, the design of the metallic mesh case enhances the heat dissipation of LRS-35 and 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 0.2W), it allows the end system to easily meet the worldwide energy requirement. LRS-35 has complete protection functions and 5G anti-vibration capability; it complies with 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-35 series serves as a high-price-to-performance power supply solution for various industrial applications.

OTHERS

| MTBF| 763.6K hrs min.     MIL-HDBK-217F (25℃)
DIMENSION| 998230mm (LWH)
PACKING| 0.23Kg ; 60pcs/14.8Kg/0.88CUFT
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 the low line to the high line at the 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 an increase of the setup time.

7.  5V when the load factor is 0~50%, the switching power is reduced by burst operation, which will cause ripple and ripple noise to go beyond the specifications.

8.  The ambient temperature derating of 5℃/1000m is needed for operating altitude greater than 2000m(6500ft).

9.  The power supply is considered a component that will be installed into the 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.”
