Flatpack Rectifiers: HE, SHE and SHE+ Efficiency
Efficiency is more than a technical specification. Every rectifier converts AC power into DC power. During this process, a portion of the energy is lost and dissipated as heat.The higher the efficiency:
• The lower the energy losses
• The lower the cooling requirements
• The lower the operating costs
• The smaller the environmental footprint
• The higher the overall system efficiency
Delta Eltek offers three efficiency levels within the Flatpack family: HE, SHE and SHE+
HE (High Efficiency): The proven industry standard
HE rectifiers have established themselves as a reliable and cost-effective solution for a wide range of DC power applications. Key benefits:
• Efficiency up to 96.5%
• Proven reliability
• Suitable for most standard applications
SHE (Super High Efficiency): Lower operating costs. Reduced heat generation.
SHE rectifiers build on the proven Flatpack architecture and introduce advanced semiconductor technology to further reduce conversion losses. Key benefits:
• Efficiency up to 97.8%
• Reduced energy consumption
• Lower cooling requirements
• Reduced heat dissipation
• Lower total cost of ownership
SHE is particularly attractive for customers who prioritize operational savings and sustainability without compromising reliability or system availability.
SHE+ (Super High Efficiency Plus): Maximum efficiency for critical infrastructure
For organizations where every watt matters, SHE+ represents the highest efficiency level within the Flatpack family. Key benefits:
• Industry-leading efficiency of up to 98%
• Lowest energy losses
• Maximum reduction in cooling demand
SHE+ is often selected for mission-critical installations where systems operate continuously, and long-term OPEX reduction is a key objective.
