The ZTE ZXD2400 is one of the most widely deployed 48V telecom rectifier modules of the past decade — a 50A-class hot-swap module that powered large fleets of ZTE ZXDU58 and ZXDU68 embedded power systems. Because ZTE refreshed the hardware platform during its production life, today’s market carries two commonly traded revisions: V4.3 and V4.6. This guide explains what V4.6 publishes on its datasheet, how to identify the version on a physical module, and what to check before buying — especially for mixed or refurbished lots.
What the V4.6 datasheet publishes
| Item | ZXD2400 (V4.6) |
|---|---|
| Rated output power | 2400 W |
| Maximum output power | 3195 W |
| Maximum output current | 50 A |
| DC output | -48 VDC nominal |
| AC input window | 80–300 VAC wide-range |
| Host systems | ZTE ZXDU58, ZXDU58 W121, ZXDU68 series |
| Module format | Hot-swap, front-panel insertion |
ZTE has not published a comparable full public datasheet for V4.3 in the same format. Treat any claimed V4.3 figures as unverified unless they are confirmed from the module’s own nameplate or an original datasheet PDF — do not assume V4.3 shares V4.6’s numbers.
How to identify the version on a physical module
- Nameplate: the rear/side label carries the model and revision (V4.3 or V4.6), part number and date code. This is the primary identification method.
- Supervision readout: a module installed in a ZXDU58/ZXDU68 cabinet reports its hardware version through the system supervision controller — the most reliable check for modules already installed.
- Part numbering: ZTE part numbers differ between hardware revisions; a supplier should be able to quote the exact P/N from the label.
- Cosmetics: heatsink and label layouts vary between builds, but appearance alone is not a reliable identifier — always confirm from the nameplate.
Slot and system compatibility
V4.6 is the standard fit for ZTE’s small-capacity embedded systems. In our catalog, the ZTE ZXDU58 W121 120A cabinet and the ZTE ZXDU68 B201 200A cabinet host the ZXD2400 platform — four 50A modules reach the 200A rating of the B201. Rectifier slots, mounting guides and the CAN/RS485 supervision interface are designed around the ZXD2400 family, so match the revision to what your cabinet and controller were shipped with.
Sourcing checklist for buyers
- Ask the supplier for nameplate photos showing model, revision and P/N before ordering.
- Match revisions within one cabinet — mixing V4.3 and V4.6 in the same system is not recommended practice.
- Confirm the supervision interface (CAN/RS485) matches your ZXDU controller generation.
- For refurbished lots, request tested/burn-in stock with measured output records.
- Compare against other 50A-class options in the 48V cross-reference chart and see the rectifier selection guide.
What is the difference between 2400W rated and 3195W max on the ZXD2400 V4.6?
2400W is the continuous rated output the module sustains long-term; 3195W is the maximum output power it can deliver within its operating envelope (short-term/higher load conditions). System sizing should be based on the rated 2400W figure.
Can V4.3 and V4.6 modules share the same shelf?
Both belong to the ZXD2400 family, but mixing hardware revisions in one cabinet is not recommended practice. Verify each module’s revision from its nameplate or the supervision controller, and ask your supplier to match revisions within a single system.
Which ZTE cabinets use the ZXD2400 module?
The ZXD2400 platform is the standard rectifier for ZTE’s small-capacity embedded systems, including the ZXDU58 W121 120A and ZXDU68 B201 200A cabinets. Four 50A modules deliver the 200A rating of the B201.
Does BS Comtec supply ZXD2400 modules?
Yes. BS Comtec supplies ZXD2400 modules and ZXDU58/ZXDU68 cabinets from its Singapore stock with 1-piece minimum order and 24–48 hour dispatch. Nameplate photos and test records are available on request before shipment.
