Description

LRS-350N2 series is a 350W single-output enclosed type power supply with 30mm of low profile design. Adopting the input of 115VAC or 230VAC (select by switch), the entire series provides an output voltage line of 12V, 24V, 36V and 48V. In addition to the high efficiency up to 89%, with the built-in long life fan LRS-350N2 can work under -25~+70°C with full load. Delivering an extremely low no load power consumption (less than 0.75W), it allows the end system to easily meet the worldwide energy requirement. LRS-350N2 has the complete protection functions and 5G anti-vibration capability; it is complied with the international safety regulations such as IEC/UL 62368-1. LRS-350N2 series serves as a high price-to-performance power supply solution for various industrial applications. Moreover, LRS-350N2 can provide 200% short-duration peak power for motor applications and electro mechanical loads requiring much higher power during start-up.

NOTE

1. Al parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C 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. Length of set up time s measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.

4. This power supply does not meet the harmonic current requirements outlined by BS EN/EN61000-3-2. Please do not use this power supply under the following conditions:
   a) the end-devices is used within the European Union, and
   b) the end-devices is connected to public mains supply with 220Vac or greater rated nominal votiage, and the power supply is:

   • installed in end-devices with average or continuous input power greater than 75W, or
   • belong to part of a lighting system
     Exception:
     Power supplies used within the following end-devices do not need to full BS EN/EN61000-3-2
     a) professional equipment with a total rated input power greater than 1000W;
     b) symmetrically controlled heating elements with a rated power less than or equal to 200W

5. RCM is on voluntary basis and meets relevant IEC or ASINZS standards complying with ASNZS 4417.1
