The THYROTRONIC Rectifier Series: The Heart of the System

At the core of every BEINING DC power system lies the THYROTRONIC rectifier series—a product line specifically engineered for battery-supported DC power supplies. These rectifiers are designed to excel in harsh environmental conditions where reliability cannot be compromised.

Key Engineering Features

Built for Harsh Environments
Constructed from a minimal number of carefully selected, high-reliability components, THYROTRONIC rectifiers offer exceptional mechanical and electronic resilience. They are specifically designed to withstand demanding industrial conditions, making them ideal for power plants, substations, and industrial facilities.

Advanced Power Conversion Technology

Fully controlled thyristor three-phase bridge with 6-pulse (standard) or 12-pulse (optional) configuration
State-of-the-art DSP (Digital Signal Processing) technology for precise control
Galvanic isolation for enhanced safety
Input voltage range: 120V to 690V
Output voltage range: 18V to 312V

Universal Battery Compatibility
THYROTRONIC rectifiers feature an electronically controlled output characteristic (IU characteristic according to DIN 41773), making them suitable for all battery technologies—including lead-acid batteries, NiCd batteries, and modern lithium-based solutions.

Intelligent Charging Management

BEINING DC power systems incorporate sophisticated charging algorithms designed to maximize battery life and system availability.

IU Charging Characteristic

The rectifier automatically adjusts its charging profile based on battery condition:

When batteries are deeply discharged, the system operates in the I-branch, delivering constant current charging
Upon reaching the set voltage threshold, it transitions to the U-branch for constant voltage charging
Automatic boost charging activates when needed, switching back to float charging after programmed intervals

Temperature-Controlled Charging

The charging characteristic automatically adapts to ambient temperature conditions, ensuring optimal charging regardless of environmental variations—a critical feature for outdoor installations and unconditioned spaces.

Comprehensive Monitoring and Control

Display and Control Unit

The system features a user-friendly interface integrated into the front door of the rectifier housing. Operators can:

Set customizable limit values for various measurement channels
Trigger error or warning messages when thresholds are exceeded
Visualize system status and acknowledge alarms

For enhanced usability, BEINING offers an optional 10-inch touch display, delivering intuitive operation and clear visualization of all system parameters.

Advanced Monitoring Capabilities

The system continuously monitors:

Network conditions — grid stability and power quality
Battery and DC voltage — overvoltage and undervoltage detection
Temperature — critical for battery health and system safety
Ground faults — insulation monitoring for enhanced safety

Communication Protocols

BEINING systems support multiple industrial communication standards, including MODBUS and IEC 61850, enabling seamless integration with SCADA systems and building management platforms.

Built-In Diagnostic Functions

Automatic Battery Circuit Test

The system can be programmed to perform periodic battery circuit tests. During testing, the rectifier output voltage briefly drops to a preset level, causing a minimal discharge. If the battery voltage remains above the threshold, the circuit is confirmed healthy. Should it fall below the limit, a "battery circuit fault" alarm is triggered.

Automatic Battery Capacity Test

For comprehensive health assessment, the system can perform automated capacity testing:

Constant current discharge while recording voltage and current curves
Comparison with manufacturer data sheet values
Calculation of remaining battery capacity and remaining runtime under current load
Automatic return to charging mode upon test completion

Remaining Battery Life Display

Operators can monitor estimated battery lifespan directly from the system interface—a valuable tool for preventive maintenance planning.

Operational Flexibility

Parallel Operation with Load Sharing

BEINING rectifiers support parallel operation with multiple units:

Active load sharing for symmetrical distribution across all connected rectifiers
Passive load sharing suitable for simpler configurations
N+1 redundancy capability to ensure system availability even if one unit fails

Line Resistance Compensation

For installations with long battery connection cables, the system can compensate for voltage drops by entering cable length and cross-section parameters—ensuring the battery receives the correct charging voltage regardless of distance.

Adjustable Automatic Charging

The automatic boost charging function is fully programmable and can be enabled or disabled as application requirements dictate. Manual override options are also available for operator convenience.
