24VDC, 1A power delivery for Growlink LINKS HUB and connected LINKS modules.
The Growlink LINK Power Supply (1 Amp) is the dedicated 24VDC wall adapter that powers the LINKS HUB and its connected automation modules — a direct replacement or expansion spare engineered specifically for the LINKS ecosystem. Compact, built for continuous use in high-humidity grow environments, and ships with international plug adapters for multi-site flexibility.
The Growlink LINK Power Supply (1 Amp) is a 24VDC, 1A AC/DC wall adapter built specifically for the Growlink LINKS ecosystem. Its primary role is powering the LINKS 8-Port Device HUB — the central hub that connects and distributes power and data to up to eight downstream LINKS modules over standard RJ-45 cables. Without a stable, correctly rated power supply, the HUB and its connected devices cannot operate reliably.
This is not a generic wall adapter. It is matched to the voltage and current requirements of the LINKS HUB and the modules that draw from it. Growlink's own documentation specifies the 24VDC 1A supply as the required input for the HUB; using an unrated substitute risks unstable communication between LINKS devices or damage to connected modules. This unit is the correct, manufacturer-specified part.
This PSU is the right order for three situations: (1) a replacement — the original supply included with a LINKS HUB was lost, damaged, or failed; (2) an expansion — you are adding a second LINKS HUB to a new grow room or facility wing and need a dedicated supply for it; or (3) a spare — facilities running mission-critical automation keep a spare PSU on the shelf because a failed wall adapter should not be the reason a veg or flower room loses automated control.
It is also the correct power supply for licensed operators deploying Growlink across multiple buildings, container farms, or greenhouse rows where a HUB is installed at each zone. Each HUB requires its own 24VDC 1A supply — this unit covers that requirement per install point.
The supply outputs a regulated 24VDC at 1A — matching the LINKS HUB's rated input and the 1A of shared power the HUB delivers across its eight device ports. The compact barrel-connector design plugs directly into the HUB's dedicated power input port with no wiring required. The unit ships with international plug adapters, which is relevant for multi-country operators or facilities sourcing equipment centrally for builds across U.S. and international sites.
Construction is rated for continuous use in cultivation environments — high relative humidity and temperature swings that would degrade an off-the-shelf consumer adapter over time. The form factor is small enough to tuck behind a control panel or mount alongside a HUB without consuming significant enclosure space.
In a standard LINKS deployment, the HUB is the central node for climate, lighting, irrigation, substrate, and nutrient LINKS modules. The HUB connects to the local network via Ethernet or 2.4GHz Wi-Fi, receives commands from Growlink OS, and distributes power and data to each connected LINKS device over RJ-45 — up to 1A total shared across all ports, with device connections reaching up to 1,000 feet from the HUB.
The LINK Power Supply (1A) is what keeps that HUB live. Facilities building out new rooms, adding HUBs to scale zone-level automation, or commissioning a redundant spare supply should add this unit alongside each HUB in the bill of materials. It is a low-cost, high-consequence component — getting it spec'd correctly from the start avoids a down system waiting on a part.

Yes. Growlink's own Quick Start Guide for the LINKS HUB specifies a 24VDC 1A power supply as the required input. The GL-LINK-PSU-1A is exactly that — the manufacturer-specified adapter for the HUB.
Growlink advises using only the intended or included power supply with LINKS devices. A non-specified adapter may have unstable regulation, incorrect barrel dimensions, or insufficient current headroom — any of which can cause intermittent device communication or hardware damage. Stick with the rated part.
One supply per HUB. Each LINKS HUB has its own dedicated barrel-connector power input and requires its own 24VDC 1A adapter. If you are adding a second or third HUB to scale a multi-room facility, order one GL-LINK-PSU-1A per additional HUB.
The LINKS HUB distributes up to 1A total across all eight of its RJ-45 device ports. Individual LINKS modules (sensors, climate devices, lighting controllers, etc.) draw their operating power from the HUB over the RJ-45 connection. The 1A PSU keeps the HUB powered so it can supply that shared current budget to all connected modules.
Yes. The LINK Power Supply ships with international plug adapters, making it compatible with multiple outlet types. This is useful for operators managing facility builds across the U.S. and international sites from a single procurement source.
