48V DC Power Plant | Telecom DC Power Supply System for Communication Base Station

• Fanless Self-cooling & Low Noise

No built-in fan, zero running noise, no dust accumulation, greatly reduce maintenance frequency, suitable for quiet indoor machine room and unattended sites.

• High Efficiency & Energy Saving

High-frequency soft-switching technology, conversion efficiency ≥92%, reduce power consumption and electricity cost for mass base station deployment.

• Hot Swap + N+1 Redundancy

Modules can be plugged and replaced live without power cut. N+1 redundant design ensures the whole system keeps running when single module fails, guaranteeing telecom service continuity.

• Intelligent Remote Monitoring

RS485 Modbus interface, real-time monitoring of voltage, current, temperature, alarm status; support battery temperature compensation charging, prolong battery service life.

• Complete Multi-level Protection

Full protection against overvoltage, overcurrent, overload, overtemperature, input abnormal and reverse polarity. Fast lockout & self-recovery mechanism to protect load and battery.

• Excellent Parallel Current Sharing Performance

Multi-module parallel current sharing deviation ≤±3%, stable expansion for different site capacity requirements, flexible capacity upgrade.

• Wide Working Temperature Range

Industrial grade design, stable operation under harsh temperature environment, adapt to tropical, subtropical and highland telecom sites.

• Factory Direct Supply

1.Our TH series 48V telecom rectifier modules have been exported to multiple countries and regions for telecom infrastructure projects:

2.Central Asia: Uzbekistan, Kazakhstan — 5G rural base station and transmission station DC power retrofit projects

3.East Africa: Kenya, Tanzania — operator BTS power system tender, matched with lithium battery backup

4.Eastern Europe: Belarus — indoor telecom room integrated DC power plant project, N+1 redundant configuration

5.Southeast Asia: Myanmar, Cambodia — small cell and microwave relay station power supply

6.South Pacific: Fiji, Papua New Guinea — off-grid hybrid solar + grid telecom power solution

7.Our customers include local telecom operators, system integrators, power distributors and engineering contractors. The modules run stably in high temperature, high humidity and unstable grid areas, and gain consistent feedback on low failure rate and easy maintenance.

Q1: What is the difference between TH48T50ZZ-220 and fan-cooled rectifier modules?

A1: This model is fanless self-cooling. The biggest advantage is no fan failure, less dust, lower maintenance, quieter. It is more suitable for indoor machine rooms and unattended sites. Fan-cooled models are chosen for high heat density and narrow cabinet space.

Q2: Can multiple TH48T50ZZ-220 modules work in parallel?

A2: Yes. Support multi-module parallel and automatic current sharing, current sharing deviation ≤±3%. Support N+1 redundancy design.

Q3: What communication protocol does it use? Can I connect to my existing monitoring system?

A3: Standard RS485 Modbus-RTU. We provide complete protocol manual. You can integrate it into your own SCADA, monitoring unit or BMS system.

Q4: Can this module charge lithium battery?

A4: Yes. The output voltage is adjustable 40~58VDC. You can set charging voltage and floating voltage according to lithium battery or lead-acid battery specification. We suggest using with a dedicated monitoring unit for battery management.

Q5: What certifications can you provide for import customs clearance?

A5: CE, RoHS, EMC test report, factory inspection report. We can apply for Form E, CO and other preferential certificates as required.

Q6: What is your MOQ?

A6: 1 pcs for sample testing; bulk order price for quantity ≥10 pcs. Mixed order with other TH series rectifiers is acceptable.

Q7: How about after-sales if the module fails after arrival?

A7: Within warranty period, we judge the failure cause. For quality issues, we arrange replacement or repair. Buyer only needs to provide fault log and photos/video.
