Varnix Technology Co., Ltd. has specialized in industrial-grade power conversion equipment since 2003. Our switch mode rectifier (SMR) systems and 19-inch rack-mounted embedded power systems convert AC utility power (110VAC/220VAC wide-range) into stabilized, low-ripple 24VDC or 48VDC power for telecom base stations, network servers, and critical DC plants.
Engineered for high uptime, every rectifier module features active power factor correction (PFC > 0.99), modular N+1 redundancy, smart battery management, and digital monitoring via RS485/SNMP.
Standard models available with flexible order quantities (1 to 5 units MOQ), short lead times, and comprehensive project customization.
At Varnix Technology Co., Ltd., every single rectifier unit and power sub-rack is assembled and tested in our SGS-audited 1,229 m² facility in Guangdong, China. From raw material inspection through full-load burn-in, we guarantee compliance with global telecommunication standards.
Compare standard configurations across 1U, 2U and 3U embedded platforms. Custom input voltages (such as 110VAC or 3-phase 380VAC) are built upon request.

Active Power Factor Correction circuitry limits grid distortion (THD < 5%), protecting upstream diesel generators and adjacent transmission gear.
Replace or add rectifier sub-modules while the system stays fully energized without disrupting live telecommunications traffic.
Integrated safeguards include AC input over/under voltage shutdown, DC output surge suppressors, thermal cutoff, and continuous short-circuit protection.
Contact our senior power engineers with your rack dimensions, current requirements, and input AC ranges. We provide tailored schematic reviews and rapid B2B OEM quotations.
Everything procurement officers and project managers need to know about our rectifier product line.
An embedded rectifier system is purpose-built for telecommunications and critical networks. It integrates AC power distribution, DC load breakers, modular rectifier units, and a dedicated battery charging and monitoring controller with Low Voltage Disconnect (LVD). A basic industrial power supply typically provides only raw DC voltage conversion without integrated battery management or telecom alarm contacts.
Yes. As a verified manufacturer since 2003, Varnix Technology Co., Ltd. designs and manufactures both standard 220VAC modules and wide-input 90V-280VAC / 110VAC single-phase or 380VAC three-phase systems for international grid compatibility across the Americas, Europe, Africa, and Southeast Asia.
Every single power unit manufactured at Varnix passes a strict 17-point production protocol, including 100% oscilloscope waveform verification, output voltage precision calibration with digital multimeters, and high-temperature full-load aging tests (burn-in) before packaging.
Catalog rectifier modules and sub-racks have an MOQ of just 1 to 5 units, making prototype validation easy for system integrators. Standard production batches are completed within 10 to 20 working days, backed by sea, air, and express logistics support.
All Varnix rectifier systems include factory warranty coverage specified directly in commercial contracts. Our engineering team provides 24/7 technical support, schematic documentation, and spare module availability.
