AJAX – PSU 4.2VDC-16VDC HUB2,HUB2+ (Black)

AJAX PSU 4.2VDC-16VDC for HUB2 and HUB2+ (Black)

The AJAX PSU 4.2VDC-16VDC is a black power supply unit designed for the AJAX Hub 2 and Hub 2 Plus control panels. It provides the electrical supply that these alarm system hubs need to run, so the system can be powered from a dedicated unit that matches the hub’s input range.

The supply operates across a voltage range of 4.2 VDC to 16 VDC, as stated in the product description. The black finish matches the colour scheme of the hub it is intended for, so the unit blends in with the rest of the installation.

This item is an accessory for the AJAX alarm system. It is meant for buyers who already use or plan to use a Hub 2 or Hub 2 Plus and need a replacement or additional power supply. Check the product description and your existing system before ordering to confirm that it suits your setup.

Because it is a power component, it belongs with other alarm system parts such as control panels and hub accessories. Keep it with your installation documents so you can identify it easily later.

If you are building or maintaining an AJAX security system, this power supply is a straightforward way to keep the hub running. Order it together with the hub or related components to make sure the whole system works as a set.

AJAX PSU 4.2VDC-16VDC for HUB2 and HUB2+ (Black)

AJAX - PSU 4.2VDC-16VDC HUB2,HUB2+ (Black)

The AJAX PSU 4.2VDC-16VDC is a black power supply unit made for the AJAX Hub 2 and Hub 2 Plus. The hub is the central unit of an AJAX wireless alarm system, and it needs a stable power source to keep the system running. This power supply is designed for that purpose and is sold as an accessory for these two hub models.

Power supplies are a basic part of any alarm installation. Without a reliable supply, the control panel cannot operate, and the connected sensors and keypads cannot report to it. Choosing a unit that matches the hub’s specified input range is important, and this product is listed for a range of 4.2 VDC to 16 VDC.

Key features

  • Compatible with AJAX Hub 2 and Hub 2 Plus control panels
  • Input voltage range: 4.2 VDC to 16 VDC
  • Black colour finish
  • Accessory for the AJAX alarm system
  • Supplied as a single power supply unit

Specifications

The product description gives the voltage range and the compatible hub models. Other technical details, such as current rating, dimensions, connector type and weight, are not stated in the supplier information. Check the product documentation or contact the supplier before installation if you need these details.

Typical uses

This power supply is intended for security installations that use the AJAX Hub 2 or Hub 2 Plus. Typical uses include:

  • Replacing a faulty or worn power supply on an existing AJAX hub
  • Equipping a new AJAX system with a dedicated power source
  • Keeping a spare unit on hand for maintenance
  • Supplying power to a hub in a home, office or small business alarm setup

Compatibility and selection

Before ordering, confirm that your hub is a Hub 2 or Hub 2 Plus and that your installation falls within the 4.2 VDC to 16 VDC range. Matching the product to the hub model is the most important step. If you are unsure, ask for advice before buying, because a mismatched power supply can prevent the system from working correctly.

Installation and handling

Power supplies should be installed by someone with experience in low-voltage alarm wiring. Turn off power before connecting or disconnecting the unit, and follow the instructions supplied with your AJAX system. Store the unit in a dry place when not in use, and keep it away from sources of heat and moisture.

Why choose this product

The AJAX PSU 4.2VDC-16VDC gives you a dedicated power source for the Hub 2 and Hub 2 Plus. It is a simple, focused accessory for users who want their alarm system to stay powered and operational. Pairing it with the correct hub and keeping a spare on hand can reduce downtime if a power problem occurs.

For a complete alarm system, consider this unit alongside the other AJAX components you plan to use, such as sensors, keypads and panic buttons. Planning the full system at the start makes installation smoother and helps you choose parts that work well together.
