Industrial & Telecommunications Applications

Telecommunications Base Stations: Provide reliable DC power for cellular base stations, microwave relay stations, and fiber optic network equipment. The 220VDC output supports standard telecom battery banks and critical communication infrastructure requiring uninterruptible power supply (UPS) backup. High power factor (>0.94) reduces utility costs and minimizes harmonic distortion on the AC grid.

Utility Substation Control Systems: Power SCADA equipment, protective relays, and remote terminal units (RTUs) in electrical substations. The wide input voltage range (323-475VAC) accommodates grid voltage fluctuations common in utility environments, while the rugged construction withstands the harsh electromagnetic environment near high-voltage switchgear and transformers.

Industrial DC Distribution Panels: Serve as charging modules in DC power distribution systems for manufacturing facilities, chemical plants, and oil & gas installations. The RS485 communication interface enables integration with building management systems (BMS) and supervisory control networks for centralized power monitoring and predictive maintenance.

Railway Signaling & Control: Supply DC power for railway signaling systems, track circuits, and interlocking equipment. The module's wide operating temperature range (-25°C to +55°C) accommodates outdoor equipment shelters and trackside installations subject to extreme weather conditions.

Data Center Infrastructure: Support legacy 220VDC power distribution architectures in telecommunications data centers and carrier hotels. The high-frequency switching design minimizes heat generation and acoustic noise (<55dB), critical for installations in occupied equipment rooms and colocation facilities.

Advanced Power Conversion Architecture

Sophisticated design for maximum efficiency and reliability:

Three-Phase Passive PFC: The input stage employs a three-phase passive power factor correction circuit that rectifies and filters AC input while maintaining power factor >0.94. This design eliminates the need for active PFC components, improving reliability and reducing electromagnetic interference. Compliance with GB/T 17794.2.2-2003 and DL/T781-2001 ensures compatibility with utility grid requirements.

High-Frequency DC/DC Converter: The output stage utilizes pulse-width modulation (PWM) control to deliver stable, regulated DC voltage across the full load range. High-frequency switching (typically 50-100kHz) enables compact transformer design and fast transient response to load changes, critical for maintaining voltage stability during equipment startup and fault conditions.

Intelligent Fan Control: Temperature and load-dependent fan speed control optimizes cooling efficiency while minimizing acoustic noise and extending fan service life. The fan operates at three speeds: stopped (light load/low temperature), half-speed (moderate load), and full-speed (heavy load/high temperature), reducing energy consumption and noise pollution in occupied spaces.

Diagnostic & Monitoring Features

Comprehensive status indication and remote management capabilities:

• LED Status Indicators: RUN (green) for normal operation, ALM (yellow) for warnings, Fault (red) for critical failures
• Front Panel Display: 3-digit LED shows output voltage and current with A/V button to toggle display modes
• Fault Code Display: Diagnostic fault codes displayed on LED for rapid troubleshooting and maintenance
• RS485 Communication: Real-time monitoring of voltage, current, temperature, and alarm status via Modbus RTU or proprietary protocol
• Remote Control: Adjust output voltage setpoint, enable/disable module, and reset alarms through communication interface
