MeanWell BIC-5K Series Power Supply

High-Performance Bidirectional AC/DC Power Solution for Energy & Storage Systems

In today’s energy-intensive applications such as energy storage systems (ESS), industrial bidirectional power conversion and hybrid grid applications, power supplies must do more than simply convert AC to DC. The MeanWell BIC-5K Series represents a new class of bidirectional power supply systems that combine high efficiency, digital control, and multiple protection features in a compact 1U profile. Designed to support both AC/DC and DC/AC modes with energy recycle functionality, the BIC-5K Series is tailored for smart energy, industrial automation, and advanced storage environments.

What sets the BIC-5K apart is its full digital design and exceptional performance. With 93 % conversion efficiency, ultrafast switching between AC and DC modes in under 1 ms, and support for remote communication interfaces like CANbus or Modbus-RTU (RS-485), this power module enables precise system control, flexibility, and energy optimization in demanding applications.

Why Bidirectional Power Supplies Matter

Traditional one-way power supplies are designed to convert AC mains into DC for loads. In contrast, bidirectional power supplies such as those in the BIC-5K Series enable energy to flow in both directions — making these units ideal for:

• Grid-tied energy storage systems, where surplus energy may need to be returned to the grid

• Hybrid AC/DC microgrids aiming to balance demand and supply

• Battery charging and regenerative systems in industrial applications

• Energy recycling in systems with dynamic load switching

This bidirectional capability aligns with broader trends in renewable energy and energy storage deployments, where systems increasingly require two-way energy transfer to maximize efficiency and reduce operating costs.

Core Features of the BIC-5K Series

Unlike conventional power supplies, the BIC-5K Series integrates several advanced design features that improve both performance and reliability:

• Full Digital Control: Ensures precise and repeatable AC/DC and DC/AC conversion behavior across varying load conditions.

• 93 % Conversion Efficiency: Minimizes losses and thermal loading in both conversion modes, supporting energy-efficient system design.

• Ultrafast Switching (< 1 ms): Crucial for systems requiring rapid mode transitions between charging and discharging.

• Active Current Sharing: Parallel multiple units to scale total system power while maintaining synchronization.

• Comprehensive Protections: Built-in protections for anti-islanding, AC failure, over/under voltage, over current, and over temperature help safeguard sensitive loads and components.

• Communication Interface Optional: Support for CANbus or Modbus-RTU enables seamless integration into modern energy management systems.

• Industry Certifications: Meets CB, TUV, and UL 62368-1 safety standards and is designed in compliance with IEC 62477 regulations for power electronics.

These features make BIC-5K ideal for integration into advanced architectures where reliability and intelligent control are essential.

Typical Applications

The versatility of the BIC-5K series power supply opens up a broad range of practical use cases in modern energy and industrial systems:

1. Energy Storage Systems (ESS): Use in bidirectional energy flow systems, enabling efficient charging and discharge cycles.

2. Grid and Microgrid Interfaces: Support AC/DC and DC/AC conversion in hybrid microgrids, contributing to demand balancing and peak shaving.

3. Industrial Regenerative Systems: Ideal for systems that harvest energy during braking or dynamic loads.

4. Smart Energy Management Projects: Integration with supervisory control and data acquisition (SCADA) systems via standard communication protocols.

5. Backup and UPS Systems: Seamless bidirectional power delivery in critical backup power scenarios.

With the growing focus on decentralized renewable energy and flexible energy solutions, products like the BIC-5K Series are increasingly chosen for both new installations and renovations of existing power systems.
