RAC03-K/GB Series: RECOM’S 3W AC-DC Energy Efficient Modules

2 months ago by Luke James

With new IoT applications on the horizon in 2020 and beyond, RECOM has created a new high-quality, no-load power consumption, and cost-effective series of interconnected application modules having a minimal 1 x 1 inches footprint size which offers optimal standby mode.

Considering technological advancements for smart applications which have become a part of several electronic products, RECOM has designed an optimized solution for converting VAC to VDC in form of a module having nominal footprint size of 1 x 1 inches.

One of Austria’s most renowned tech companies, RECOM manufactures power supply solutions rated from 0.25W to 960W with a global network of clients. The company has been in operation for over 45 years and serves a global clientele base.

RECOM’s latest RAC3 is a precise global solution for routine supplies that achieves an 80% energy efficiency from full load to standby mode, ensuring maximum energy savings for all load conditions. 

 

Applications

The product is available as two families - the K-Series and the GB-Series. The product is suitable for industrial applications, since the company states that it can work under temperatures from -40°C to +85°C smoothly. It can also convert various AC voltages ranging from 85VAC, 264VAC, 305 VAC and 528VAC to 3.3VDC to 48VDC. The RAC03-GB has built-in Class B/FCC Part 15 EMC filters which are certified to IEC/EN/UL60950-1, IEC/EN/UL62368 and EN61558 safety standards. 

 

Technical Features of RAC3

Apart from the smooth and sleek design of RAC3, it includes:

  • Enclosed module type

  • Maximum current output: 900mA

  • Universal input

  • Through-hole mounting 

  • 4-Dip module

  • Footprint: 1.12" L x 0.93" W x 0.70" H (28.5mm x 23.5mm x 17.9mm)

 

Benefits of RAC3

  • High power density

  • Optimal standby load

  • No-load power consumption

  • Efficiency 69% (avg)
