PRODUCT DESCRIPTION
TP-Link Omada 150W AC Power Supply Module (PSM150-AC) - Local Warranty
The PSM150-AC is the hot-swappable 150 W AC power supply module for the JetStream T3700G-28TQ stackable L3 managed switch. It converts mains to 12 V DC at 12.5 A inside the switch chassis, and because a second module can run alongside it, a core switch can be given a redundant supply - or a failed supply replaced - without taking the network down.
150 W of 12 V DC Output for the T3700G-28TQ
The module accepts 100-240 V at 50/60 Hz, 2.5 A, and delivers 12 V DC at up to 12.5 A for a maximum output of 150 W. That is sized for the T3700G-28TQ, TP-Link's 28-port Gigabit stackable L3 managed switch, and TP-Link names that model explicitly as the compatible host. It is a chassis module, not a desktop brick: it slots into the switch's power bay and is held by the switch's own mechanics.
Hot-Swappable, So the Switch Stays Up
TP-Link lists the PSM150-AC as hot-swappable. In a chassis fitted with two modules, either can be removed and replaced while the switch continues forwarding traffic - which is the whole reason redundant supplies exist in a core or distribution switch. For sites with a maintenance window measured in minutes rather than hours, that turns a power-supply failure from an outage into a scheduled swap.
Protection Circuitry on Every Rail
The module carries output over-voltage, under-voltage, short-circuit and over-current protection, so a fault downstream or a wiring mistake during installation is contained rather than propagated into the switch. Three front indicators - Power, PS OK and Fault - give an at-a-glance state from the rack aisle, so a technician can identify a failed module without opening a management session.
Rack-Ready Mechanics and a Wide Thermal Envelope
At 120 x 213 x 41.8 mm the module is built to the switch's bay dimensions. Its published operating range is 0 to 70 °C with 10% to 90% non-condensing humidity - unusually wide for a power module and well beyond what a conditioned comms room demands, which gives headroom in a warm riser cupboard or an unconditioned plant space. Storage tolerance runs from -40 to 80 °C.
Ideal For
Singapore sites running the JetStream T3700G-28TQ that want a redundant second supply fitted, and IT teams holding a spare module against a power-supply failure in a core switch. TP-Link lists this model as End of Life, so availability is limited - talk to SourceIT about current stock and about the correct module for newer Omada chassis switches. Supplied by SourceIT with local Singapore warranty, GST invoice and project pricing on request.

Compatibility & Software Support
The PSM150-AC is a passive power module. It carries no firmware, no licence and no management interface of its own, so it is not adopted into an Omada Software, Hardware or Cloud-Based Controller. The host switch owns the bay, reports the module's state and is the device you manage.
| Compatible Switch | T3700G-28TQ — JetStream 28-Port Gigabit Stackable L3 Managed Switch |
| Omada Controller | Not applicable — the module has no management plane; manage the host switch instead |
| Installation | Fits the host switch's power supply bay; hot-swappable in a chassis fitted with a redundant module |
| Configuration | None — the module has nothing to configure |
TP-Link names only the T3700G-28TQ as the compatible host for this module. If your switch is a different JetStream or Omada model, send us the model number and we will confirm the correct power module rather than assume this one fits.

Frequently Asked Questions — PSM150-AC
Which switches does this module fit?
TP-Link lists the T3700G-28TQ. It is a chassis module sized for that switch's power bay — not a universal or external power supply. Send us your switch model and we will confirm the right part.
Can I replace it without shutting the switch down?
Yes, where the chassis is fitted with two modules. TP-Link lists the PSM150-AC as hot-swappable, so one module can be removed and replaced while the other keeps the switch running.
What warranty does SourceIT provide?
Local Singapore warranty. TP-Link's published replacement-warranty tiers do not name power supply modules, so we do not quote a duration we cannot verify — ask us for the current term in writing before you order. Every PSM150-AC sold by SourceIT comes with a GST invoice.
Can SourceIT quote this for a project or tender?
Yes. Send the bill of materials and we will quote the whole Omada build — controller, gateway, switching, access points, optics and power modules — with local warranty and support.
