TONHE Fan Cooling Rectifier Module, 110V DC Charging Power Supply Module

The TONHE Fan Cooling Rectifier Module is a high-performance 110V DC charging power supply module engineered for mission-critical industrial and power infrastructure applications. Built on advanced resonant switching technology, this module converts standard AC input into stable, regulated 110VDC output with exceptional efficiency (≥91%) and ultra-low ripple.
Designed with forced-air cooling, the module maintains optimal operating temperatures even under continuous full-load conditions, ensuring reliable 24/7 performance in demanding environments. Its compact form factor and lightweight construction make it an ideal space-saving solution for integrated DC power systems, battery charging systems, and industrial control cabinets.
As a core component of DC uninterruptible power systems, the TONHE 110V rectifier module provides clean, filtered DC power for battery banks and critical loads simultaneously — protecting sensitive equipment from voltage fluctuations and power interruptions.

1. High Efficiency & Energy Savings
   With ≥91% conversion efficiency, the TONHE fan cooling rectifier module minimizes energy loss and reduces operational costs. Advanced resonant switching technology lowers heat generation, extending component lifespan and reducing cooling requirements.
2. Forced-Air Cooling for Continuous Operation
   The integrated intelligent fan cooling system maintains internal heatsink temperature rise below 50°C, enabling the module to deliver full rated power continuously without derating. The fan operates at ≤55dB noise level, suitable for indoor industrial environments.
3. Comprehensive Protection Mechanisms
   The module features a full suite of protective functions to safeguard both the unit and connected equipment:
   Output Over-Voltage Protection: Auto-shutdown at 150±5VDC
   Over-Current Protection: Current limiting at 105% rated output
   Short-Circuit Protection: Hiccup-mode recovery after fault clearance
   Over-Temperature Protection: Thermal derating and shutdown
4. Compact & Lightweight Design
   Measuring just 215 × 135.2 × 51mm and weighing only 0.7kg, this module delivers high power density in a small footprint — perfect for space-constrained installations and modular rack systems.
5. Parallel Operation Capability
   Multiple modules can be paralleled for scalable power systems with ±5% current sharing imbalance, allowing flexible capacity expansion from small standalone setups to large distributed DC power architectures.
6. Wide Input Voltage Range
   Accepts 198–253VAC input (typical 220VAC), accommodating grid voltage fluctuations common in industrial and remote locations without additional regulation.

Substation & Power Grid DC Systems
The TONHE 110V fan cooling rectifier module serves as the core charging unit in substation DC operation power systems, providing reliable power for circuit breakers, relay protection devices, and control circuits. With over 290 successful projects for 220kV–500kV substations, TONHE modules are trusted by power utilities across China and export markets.

1. Q1: What is the difference between fan cooling and natural cooling rectifier modules?
   Fan cooling modules use an integrated fan for forced-air heat dissipation, allowing higher power density and continuous full-load operation in a smaller form factor. Natural cooling (fanless) modules are silent and maintenance-free but typically larger and lower power density. Fan cooling is preferred for space-constrained installations and high-ambient-temperature environments.
2. Q2: Can multiple TONHE 110V rectifier modules be connected in parallel?
   Yes. Multiple modules support parallel operation with ±5% current sharing imbalance, enabling scalable power systems and N+1 redundancy. We recommend using modules of the same model and firmware version, and configuring them via the system monitoring unit for optimal load sharing.
3. Q3: What certifications do TONHE rectifier modules hold?
   All TONHE 110V DC rectifier modules are CE certified and manufactured under ISO9001 quality management systems. Additional certifications (UL, RoHS, etc.) can be arranged for specific export markets on request.
4. Q4: How do I adjust the output voltage for different battery charging profiles?
   The output voltage is adjustable within 99–130VDC via the module's front-panel controls or through the RS485 communication interface (on compatible models). This allows setting float charge, boost charge, and equalization voltage levels for various 110V battery systems. Consult the user manual for step-by-step configuration.
5. Q5: What is the typical lifespan of the cooling fan, and is it replaceable?
   The cooling fan is rated for 50,000+ hours of continuous operation under normal conditions. The fan is a field-replaceable component; spare fan kits are available from TONHE. For environments with high dust or humidity, we recommend periodic fan inspection and the natural-cooling series for maintenance-free operation.
