Recently, several customers have inquired about the Huawei ETP48200-C2A1 power system. However, this model has been discontinued, and only limited stock is available. As a result, we now recommend the ETP48200-C2A2 as an alternative, as it offers similar core functionality, more stable availability, and a more competitive price.Huawei has not released detailed official documentation specifically for the C2A2 model. Therefore, the comparison below is based onproduct inspection, warehouse stock analysis, and real project experience and feedback. While both models are technically similar, they differ in a few key aspects such as circuit breaker configuration, monitoring unit. We hope this summary helps you identify the model that best suits your project needs.
1.Technical Specifications
| Product Model | ETP48200-C2A2(01073534) | ETP48200-C2A1(01073243) |
| Capacity | 200A | 200A |
| Support PSU Module | R4850S1/R4850G2/R4850N2 | R4850S1/R4850G2/R4850N2 |
| Monitory Unit | SMU02C+UIM02C, Supports 12 ALM ports | SMU02B+UIM02C, Supports 12 ALM ports |
| Monitory Software | Customized software not implemented | Software customization required |
| AC input | Input: UT terminal, back cabling Surge protection: No |
Input: UT terminal, back cabling Surge protection: No |
| Battery Output | OT terminal | 2*100A/1P |
| DC output | LLCD1: OT-M8 terminal LLVD2: OT-M8 terminal BLVD: OT-M8 terminal |
BLVD: OT-M8 terminal LLVD: OT-M8 terminal |
| Installation Method | 19-inch rack-mounted | 19-inch rack-mounted |
Both models offer hot-swappable support, intelligent monitoring, remote management, and are widely used in access networks, enterprise networks, and small data centers.
2. Key Differences
| Item | ETP48200-C2A1 | ETP48200-C2A2 |
| Circuit Breaker | Built-in circuit breaker on front panel | No built-in circuit breaker |
| Monitoring Unit | SMU02B | SMU02C |
| Market Status | Discontinued, limited availability | In production, stable suppl |
| Front Panel Design | Rotary circuit breaker knob visible | Flat panel, no breaker knob |
- Circuit Breaker Configuration: The C2A1 has an integrated breaker, allowing direct power control from the front panel. C2A2 omits this feature and requires external breaker or distribution box.
- Availability: C2A2 offers a more widely availability.
- Although the ETP48200-C2A1 and ETP48200-C2A2 support different monitoring modules, both SMU02B and SMU02C are compatible with multiple remote management systems such as WEBUI and NetEco, and offer the same technical specifications.
3. Selection Recommendation
If your site already has external circuit breakers or distribution units, the C2A2 will provide better value and long-term availability. For legacy system replacements or compact installations requiring integrated power control, C2A1 may still be suitable — if stock is available.
In summary, both ETP48200-C2A1 and ETP48200-C2A2 are reliable embedded power systems, with comparable technical capabilities. The key difference lies in whether an integrated circuit breaker is needed, and in the long-term availability.
Given that C2A1 has been discontinued, we strongly recommend considering the ETP48200-C2A2 for new deployments or future-proof upgrades. If you need further details such as a quotation, stock status, or compatibility advice, feel free to contact at: csd@telecomate.com.
