| 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 3.3V, 5V, 12V, 15V, 24V, 36V and 48V.

In addition to the high efficiency up to 90%, the design of metallic mesh case enhances the heat dissipation of LRS-35 that the whole series operates from -30 ℃ through 70 ℃ under air convection wihtout a fan. Delivering an extremely low on load power consumption (less than 0.2W), it allows the end system to easily meet the worldwide energy requirement. LRS-35 has the complete protection functions and 5G anti-vibration capability; it is complied with the international safety regulation such as TUV EN60950-1, EN60335-1, EN61558-1/-2-16, UL60850-1 and GB4943. LRS-35 series serves as a high price-to-performance power supply solution for various industrial applications.

Notes on choosing a switching power supply?

Ans:

1. To increase the     reliability of the S.P.S., we suggest users choose a unit that has a rating of 30% more power than actual need. For example, if the system needs a 100W source, we suggest that users choose a S.P.S. with 130W of output power or more. By doing this, you can effectively boost the reliability of the S.P.S. in your system.
2. We also need to consider about ambient temperature of the S.P.S. and whether there is additional device for dissipating the heat. If the S.P.S. is working in a high temperature environment, we need to make some derating to the output power. The derating curve of "ambient temperature" versus "output power" can be found on our spec sheets.
3. Choosing functions based on your application:
   1. Protection function: Over Voltage Protection (OVP), Over Temperature Protection (OVP), Over Load Protection (OLP), and etc.
   2. Application function: Signaling Function (Power Good, Power Fail), Remote Control, Remote Sensing, and etc.
   3. Special function: Power Factor Correction (PFC), Uninterruptible Power Supply (UPS) function.
4. Make sure that the model qualifies for the safety standards and EMC regulations you need.

Why the input voltage marked on the spec. sheet is 88~264 VAC while the label on the power        supply says that it is 100~240VAC?

Ans:

1. During safety verification process, the agency will use a stricter standard -- ?0%(IEC60950 uses +6%, -10%) of the input voltage range labeled on the power supply to conduct the test. So, operating at the wider input voltage range as specified on the spec. sheet should be fine. The narrower range of input voltage labeled on the power supply is to fulfill the test standard of safety regulation and make sure that users insert input voltage correctly.
