Huawei R4830G2 2000W 48V High Efficiency Telecom Rectifier Module. Model R4830G2.

Product Overview

The R4830G2 converts an 80-300 VAC wide-range input into an adjustable 42-58 VDC output (default 53.5 V) with a maximum power of 2000 W at 176-300 VAC input and up to 12 A input current across 45-66 Hz. Input power factor is >= 0.99 with THD <= 5%.

Peak efficiency exceeds 96%, and the module delivers full load without derating up to +55 degC while operating from -40 to +75 degC overall. Forced-air cooling keeps noise at or below 45 dB, and the design achieves an MTBF greater than 500,000 hours for long-life unattended sites.

The compact module measures 40.8 x 105 x 281 mm and weighs no more than 1.8 kg. It is certified to TUV, CE, UL and CB requirements, meets EN 55022 Class B EMC and carries 5 kA lightning protection per YD/T 5098.

Specifications

R4830G2 vs R4850G6: which Huawei rectifier class fits your site?

Huawei’s current 48 V rectifier lines split by power class: the R4830G2 delivers 2000 W, while the R4850 series (including the current R4850G6 3000 W module) serves the 3000 W class. The practical selection rule we apply on real projects: sites with a busy-hour DC load up to roughly 1200 W run efficiently on two R4830G2 modules in N+1, because each module stays in its efficient operating band. Push a 2000 W module above 80 percent load continuously and efficiency falls off its peak; that is the point where stepping up to a 3 kW class module usually wins on energy, not just on spare capacity.

Load arithmetic example: a rural 4G site at 900 W busy hour carries comfortably on 2× R4830G2 (N+1). A dual-band 5G site at 4 to 6 kW needs three to four 3 kW modules instead — five 2 kW modules would fit the same bus but costs more shelf slots and more spares diversity. For a brand-by-brand view of which modules interchange across Huawei, Vertiv, Eltek and ZTE shelves, see our 48V rectifier cross-reference chart.

Where the R4830G2 fits: typical sites and systems

The R4830G2 targets the compact end of Huawei’s 48 V ecosystem: embedded power systems in the ETP48 series family, wall-mounted integrated cabinets, and small DC shelves where a 3 kW module would spend its life half-loaded. Typical deployments we see: fixed-line access sites and OLT rooms running 300 to 800 W, microwave repeaters, outdoor integrated cabinets for small cells, and industrial metering or SCADA cabinets that need telecom-grade -48 V in a small footprint. For sites that combine radios plus edge compute, compare it with the ETP48100-B1 100 A embedded system, which pairs this class of rectifier with distribution and monitoring in one box.

One selection note from field experience: the wide 80-300 VAC input window makes this module forgiving on weak grids — it rides through brownouts that would lock a narrower-input module out of regulation. In regions with unstable utility supply (parts of Africa, South Asia, rural Latin America), that input window is often worth more than the last percentage point of peak efficiency.

Deployment checklist for the R4830G2

Three checks before ordering. First, confirm your shelf or embedded system accepts the 2000 W mechanical format and its controller generation — modules and controllers from the same generation communicate natively; mixed-generation setups need a compatibility confirmation against your cabinet model. Second, size battery charge current: at 12 A maximum input current per module, a bank of two modules supports moderate lithium charging, but large lithium strings recovering after a deep discharge may need a third module purely for recharge rate. Third, verify environmental fit: full load without derating to +55 °C covers most outdoor cabinets, but sites above that (Gulf summers in metal enclosures) need thermal management reviewed before the module count is fixed — the same ambient logic we apply to precision cooling selection.

Key Features of R4830G2 2000W 48V

R4830G2 2000W 48V belongs to the high-efficiency rectifier module family that converts AC mains into a stable 48 V DC output. Modules of this class commonly support hot-swap installation, wide AC input windows and monitoring via system controllers.

Typical Applications of R4830G2 2000W 48V

Rectifier modules of this type are widely used in telecom power systems, data center DC plants and industrial power cabinets, usually alongside batteries for backup.

Frequently Asked Questions

How do I select R4830G2 2000W 48V for my power system?

Check output voltage, module power rating, efficiency class and compatibility with your existing rectifier shelf or controller. BS Comtec can verify fitment and propose the right quantity.

Is R4830G2 2000W 48V compatible with my existing system?

Compatibility depends on the rectifier shelf, controller and communication protocol. Send your current system model to BS Comtec and we will confirm which modules fit.

How is R4830G2 2000W 48V delivered?

Modules are packed in anti-static, export-standard cartons and shipped worldwide. Delivery time depends on stock and destination — contact BS Comtec for current lead times.

What warranty applies to R4830G2 2000W 48V?

Warranty follows the manufacturer’s policy for the specific module. BS Comtec supports testing guidance, replacement requests and RMA coordination per the terms of your order.

Where is R4830G2 2000W 48V typically used?

It is typically used in telecom base stations, central offices, data center power rooms and industrial sites requiring reliable 48 V DC conversion.

What is the difference between Huawei R4830G2 and R4850G6?

Power class and mechanical format: the R4830G2 delivers 2000 W for compact embedded systems and small shelves, while the R4850G6 is the 3000 W flagship for TP48 series cabinets and 5G-class loads. Both share the wide AC input concept, hot-swap installation and the Huawei controller ecosystem. The choice is load size and shelf compatibility, not quality tier — matching the module class to your real busy-hour load keeps every module in its efficient band.

Can I mix R4830G2 modules with other power classes in one system?

Within the same shelf generation this is technically possible, but the controller manages load sharing per class and battery recharge planning becomes more complex. Our recommendation is one class per system so N+1 arithmetic stays clean; if you must mix classes, confirm the combination against your cabinet and controller generation before ordering — send us the shelf model and we will verify.
