Product Overview
The Huawei ETP4830-A1 is a compact 1U embedded power system for access networks, transmission equipment and enterprise communication rooms. With two 1U 15 A high-efficiency rectifier modules it provides a 30 A rated output (2 kW maximum) in the smallest possible footprint, embedding directly into 19-inch or 21-inch racks and cabinets.
The wide 85-300 VAC input range tolerates unstable grids common in remote sites, while the output is adjustable from 42 to 58 VDC with a 53.5 VDC default for -48 V equipment. Both rectifiers and the SMU01A/B/C monitoring unit are hot-swappable, supporting tool-free maintenance without interrupting the load bus.
Natural cooling keeps the system silent and maintenance-free, and front inlet/outlet cabling with front maintenance simplifies installation in shallow cabinets. Intelligent battery management, rectifier dormancy and environmental monitoring via dry contact, serial or Ethernet interfaces complete a feature set aimed at unattended sites where every watt and every RU counts.

Deployment Scenarios and Sizing Notes for the ETP4830-A1
Across Europe, South America, the Middle East, Africa and Russia, the ETP4830-A1 is typically deployed where a full power cabinet is more than the site needs but a plain rectifier brick is not enough:
- OLT / ONU access nodes and CPE cabinets — one 1U frame feeds the -48 VDC transport and access shelf directly, and the second rectifier slot provides N+1 without consuming extra rack units.
- Microwave and transmission relay sites — the 85–300 VAC wide input tolerates weak generator supply, while intelligent battery management protects the backup string through long outages.
- Enterprise and edge equipment rooms — front cabling, front maintenance and natural cooling suit shallow wall-mount cabinets and unattended rooms.
Sizing guidance: with two R4815G1 15 A rectifiers the frame delivers 30 A at the 53.5 VDC default setting (≈1.6 kW continuous, 2 kW peak) — size the DC breaker and battery fuse around the connected load, and keep one slot as the N+1 reserve where uptime targets are strict. If the load budget exceeds 30 A, the like-for-like migration path is the Huawei ETP48200 embedded family, which reuses the same -48 VDC distribution logic in a higher-current frame.

Frequently Asked Questions
How do I size ETP4830-A1 Embedded 48V for my site?
Start from your steady-state and peak DC load, redundancy requirements (N+1 or 2N), battery backup time and expansion plans. BS Comtec can model these figures and propose a suitable configuration.
Can ETP4830-A1 Embedded 48V work with my existing rectifiers or batteries?
It depends on voltage range, communication protocols and mechanical compatibility. Provide your current system details and BS Comtec will review interfaces and recommend a compatible combination.
How is ETP4830-A1 Embedded 48V shipped and delivered?
Systems and modules are packed for international freight, and lead times vary by model and destination. Contact BS Comtec for current availability, shipping options and delivery schedules.
What warranty and support come with ETP4830-A1 Embedded 48V?
Warranty follows the manufacturer’s policy for the ordered configuration. BS Comtec assists with commissioning guidance, spare module supply and service coordination where required.
Where is ETP4830-A1 Embedded 48V typically deployed?
It is commonly deployed in telecom central offices, outdoor cabinets, data centers and industrial facilities that rely on stable -48 V DC distribution.
What are the key specifications of ETP4830-A1?
ETP4830-A1 key specs: -48 VDC (42-58 VDC adjustable, 53.5 VDC default); 30 A; 1U, 19-inch plug-in frame. Full datasheet and test report available from BS Comtec on request.
Does BS Comtec supply ETP4830-A1?
Yes. BS Comtec supplies ETP4830-A1 (Huawei line) from Singapore stock, MOQ from 1 piece; in-stock items dispatch within 24-48 hours with worldwide shipping.
Is there a cross-reference or equivalent for ETP4830-A1?
BS Comtec maintains a cross-reference chart covering Huawei, Vertiv (Emerson), Eltek, ZTE and Delta 48V modules. Contact us for the direct equivalent of ETP4830-A1.
Q: Can the ETP4830-A1 run on unstable generator or grid input at remote sites?
Yes — the frame accepts an 85–300 VAC wide input, which is why it is a common choice for diesel-generator sites and weak-grid access nodes. Paired with a correctly sized battery string, the SMU01 controller handles low-voltage disconnect and battery management automatically. Send BS Comtec your site input conditions for a configuration check.
Q: What if my load grows beyond the ETP4830-A1’s 30 A output?
The 1U frame tops out at two 15 A rectifier slots (30 A total, and N+1 means running below that). Beyond 30 A the practical path is the Huawei ETP48200 embedded family or an equivalent shelf system, reusing the same -48 VDC distribution approach. BS Comtec can quote both options against your measured load list.
