Data Center Cooling Systems Rectifier Module

Product Introduction
• Designed specifically for power supply of data center cooling systems
• Converts 3-phase AC input into stable 48V DC output for cooling pumps, fans and thermal control units
• Adopts digital LLC soft-switching topology for high efficiency and low heat generation
• Supports hot-swap and N+X redundant parallel operation for uninterrupted cooling power
• Built-in intelligent temperature control cooling, compatible with air cooling, rack water cooling and immersion cooling
• Equipped with multi-protection functions and digital communication for remote monitoring
• 24/7 continuous stable operation, helps reduce the overall PUE of data center

Product Parameters

Product Advantages
1.High efficiency & low heat loss for cooling system saving
LLC soft switching design keeps high efficiency in wide load range; less heat dissipation reduces extra cooling load of data center, effectively lowers PUE and electricity cost of cooling equipment.
2.Smart thermal linkage design
Fan speed dynamically follows module temperature; optional liquid cooling version available, perfect match with data center liquid cooling system, low noise and long service life.
3.Hot swap & redundant expansion
Support hot plug without power cut-off; multiple modules parallel for N+1 redundancy. Fault module replacement will not shut down cooling pumps and fan groups.
4.Full digital monitoring
Real-time upload voltage, current, temperature, alarm status; compatible with data center BMS / DC power monitoring platform, remote alarm and automatic shutdown.
5.Wide grid adaptability & complete protection
Wide AC input range, anti-surge, anti-grid fluctuation. Multiple layers of electrical protection avoid damage to cooling power loop.

Factory Advantages
1.Professional power conversion factory focused on data center and telecom rectifier modules for many years, independent R&D of hardware, firmware and thermal scheme.
2.Complete production & test line: aging test, high-low temperature test, surge test, full-load continuous running test before delivery.
3.Flexible customization: adjust power, cooling structure, communication protocol and output logic according to customer cooling system scheme; support OEM & ODM.
4.Stable delivery cycle, sufficient spare parts inventory, global after-sales technical support and 5-year warranty service.
5.Massive on-site cases: served air cooling, rack water cooling and immersion cooling projects for domestic and overseas IDC, edge computing and AI computing rooms.

Application Scenarios
1.Data center rack water cooling pump power supply
2.Immersion cooling auxiliary control & circulation pump power
3.Large air-cooled data center fan array power system
4.Edge computing room cooling control power
5.High-density AI server room thermal management power supply

FAQ
Q1: Can this rectifier work with liquid cooling cooling systems?
A: Yes. We have air-cooled standard version and dedicated water-cooled rectifier version. The water-cooled model has no built-in fan, low heat, suitable for immersion and rack liquid cooling cabinets.
Q2: Does it support N+1 redundant parallel for cooling power?
A: Supported. Modules can be paralleled with automatic load sharing. Single module failure will not affect the continuous operation of cooling pumps and fans. Hot swap is available for maintenance.
Q3: What communication interfaces are supported for data center monitoring?
A: Standard RS485, optional CAN and SNMP. It can connect to DC power monitoring host, BMS and data center upper platform to realize remote alarm and data collection.
Q4: What is the warranty period and after-sales support?
A: 5-year warranty. We provide operation manual, Modbus communication protocol document, and overseas remote technical guidance; spare parts can be sent separately for fast replacement.
