ZENITEL Motorola Wedge Power Supply For Battery Back Up, 1-10W, 6A (PMPN4076A)

The PMPN4076A is best understood as a desktop/mobile-radio power accessory rather than a conventional charger. Current listings and PDFs consistently describe it as an AC-DC power adapter with a wedge-style desktop form factor, intended to power compatible Motorola mobile radios in fixed or desk-mounted settings. One reseller specifically notes that it is compatible with desk mount, while another states that it is a power supply and desk stand equivalent to the Alfatronix AD MT-3100/DM.

The wording “for battery back up” appears repeatedly in reseller titles for this part, but the best-supported interpretation is that PMPN4076A is a power platform that can work with a backup-power arrangement rather than a battery itself. One reseller explicitly states that an external battery can be connected for backup power, and another source notes standby battery charging capability, while an older Motorola-related PDF mentions that a separate Battery Back Up Box (BBB) was being developed to add battery-backup and loudspeaker capability. Taken together, these sources suggest that PMPN4076A supports backup-power integration, but is not itself the battery module.

The “ZENITEL” prefix in some storefront titles appears to be a reseller catalog naming convention, not the actual brand of the product. Multiple listings with that wording still identify the brand as Motorola and the part number as PMPN4076A. For factual accuracy, the core product should therefore be described as a Motorola PMPN4076A wedge power supply, while noting that some resellers prepend “ZENITEL” in the listing title.

Design and Features

Wedge-style desktop form factor

One of the most distinctive aspects of PMPN4076A is its wedge-shaped desktop design. Current reseller descriptions use phrases such as “small compact design and true desktop styling”, which indicate that the unit is meant to sit on a desk or fixed surface while supporting a compatible radio installation. Another source says the device is both a power supply and desk stand, which reinforces the idea that it contributes to the physical setup of the radio as well as its electrical power.

6A continuous usage

A key technical detail repeated across current sources is 6 amp continuous usage. This is one of the clearest and most reliable specifications attached to PMPN4076A. For communications users, that figure signals that the accessory is meant for ongoing operational duty rather than casual or intermittent charging alone.

Support for battery-backup concepts

The product title used by multiple resellers includes the phrase “for Battery Back Up”, and supporting sources add useful context. One reseller states that an external battery can be connected for backup power, and another mentions standby battery charging capability. An older Motorola-related PDF also references a separate battery backup box concept associated with this desktop-style power platform. The most careful reading is that PMPN4076A is part of a broader backup-power-capable setup rather than a self-contained UPS-like device.

Cable and accessory dependencies

PMPN4076A is not entirely standalone. One current reseller states that it requires DC cable PMKN4305A and line cord, while another source says PMKN4165A is used. This inconsistency may reflect different compatible-radio families or different installation approaches, so buyers should confirm the exact cable requirement for their target radio before ordering. What is clear is that the power supply typically requires additional cabling as part of the finished setup.

Technology and Specifications

Exact product identity

The product is consistently identified across sources by the part number PMPN4076A. Reseller pages title it as Motorola Wedge Power Supply for Battery Back Up, 1–10W, 6A, while other resellers shorten that to Motorola Wedge power supply PMPN4076A or Motorola PMPN4076A Power Supply. Despite differences in catalog wording, these all point to the same core accessory.

Power range and output context

The phrase “1–10W” appears in multiple reseller titles, while one reseller describes the product as having up to 10W output power. This appears to refer to the supported radio power/output context within a desktop application rather than to the wedge power supply being a 10-watt radio itself. Since current sources do not provide a full Motorola primary datasheet here, the safest phrasing is that the market consistently associates PMPN4076A with 1–10W radio support and 6A continuous usage.

Compatibility

Compatibility is one of the most important practical details. Current reseller sources list the PMPN4076A as compatible with a broad range of Motorola equipment, including DM1400, DM1600, DM2000, DM2600, DM4000, DM4400, DM4400e, DM4401, DM4401e, DM4600, DM4600e, DM4601, DM4601e, MTM5400, MTM5500, MXM600, and TLK150. Another PDF summarizes it more broadly as suitable for DM1000, DM2000, and DM4000 Motorola devices, while another reseller describes it as compatible with DM-Series radios.

Role as a desk-tray alternative

An older Motorola-related PDF states that the PMPN4076A desktop design replaces the need for the Desk Tray (GLN7318A) or Desk Tray with Loudspeaker (RSN4005A). That is an important contextual detail because it shows PMPN4076A is not merely a generic power brick; it plays a structural role in desktop radio deployment. The same source notes suitable external loudspeaker alternatives and mentions the broader desktop-power ecosystem around the unit.

Applications and Use Cases

Fixed-position desktop radio setups

The clearest use case for PMPN4076A is turning a compatible Motorola mobile radio into a desktop-style fixed communications station. That can be valuable in dispatch points, workshops, reception points, industrial control desks, utility rooms, and security stations where a vehicle radio is desired in a permanent location. This use case is directly supported by the repeated descriptions of true desktop styling, desk mount compatibility, and power supply and desk stand functionality.

Backup-power-capable communications points

Because several sources explicitly mention battery backup, external battery connection, or standby battery charging capability, PMPN4076A is also relevant to environments where maintaining communications continuity matters. These may include security posts, facilities operations centers, transport offices, and other mission-support settings where a radio should remain usable during power interruptions. This is a grounded inference from the documented backup-power language, though the battery itself appears to be external or separate.

Support for legacy and current Motorola mobile fleets

Because PMPN4076A is compatible with a wide range of Motorola mobile radios across older and newer families, it can be useful for organizations standardizing desktop power arrangements across mixed fleets. A single accessory strategy that works across DM-series mobiles and devices such as the TLK150 may simplify procurement and maintenance.

Advantages / Benefits

Cleaner desktop deployment

Compared with ad hoc power solutions, PMPN4076A offers a more integrated desktop-styled approach. Sources repeatedly describe it as compact and true-desktop in design, which suggests it is meant to look and function like a proper workstation accessory rather than a makeshift installation.

Continuous-duty suitability

The 6A continuous usage rating is one of the strongest concrete benefits attached to the unit. That makes it more appropriate for operational communications environments than light-duty consumer adapters.

Flexibility around backup power

The repeated references to external battery backup, battery charging capability, and a broader backup box ecosystem suggest that PMPN4076A is useful where resilience matters. For communications users, this can be a significant practical advantage.

Broad radio compatibility

Because the unit is associated with multiple Motorola radio lines, buyers supporting larger or mixed fleets may find it more versatile than a model-specific desktop power solution.
