Akubela KNX Power Supply 960mA DIN Rail Bus Power Module

Akubela KNX Power Supply 960mA (KXPW-B1A960)

The Akubela KXPW-B1A960 is a DIN rail mounted power module built specifically for KNX/EIB bus lines. It delivers a stable, filtered bus voltage to keep sensors, actuators, switch modules, panels and gateways on the line communicating reliably, while an auxiliary output can power connected terminal devices directly. Designed for integrators and electricians working on residential or light commercial automation projects, it forms the electrical backbone of any Akubela or standard KNX TP installation.

Key Features

• Combined bus output current of up to 960mA across the power supply's two channels
• Dedicated bus terminal for stable KNX line power and telegram signal transmission
• Separate auxiliary output providing regulated 30VDC to nearby terminal devices
• Automatic overload protection that cuts power and flags a fault condition
• Automatic short-circuit protection to safeguard connected KNX devices
• Remote bus reset capability for quick troubleshooting without a site visit
• Compact DIN rail housing for tidy installation inside distribution or comms cabinets
• Built-in choke for clean separation of power and data signals on the bus line
• Backed by a standard 2-year manufacturer warranty

Powering Growing KNX Systems

As a KNX installation expands beyond a handful of devices, bus segments need dependable, well-regulated power to avoid dropouts, false telegrams or intermittent faults. The KXPW-B1A960 is sized to support a full line of KNX actuators, sensors, switch modules, dimmers, curtain controllers and Akubela HyPanel touch panels from a single DIN rail unit. It suits new-build smart home wiring, retrofit upgrades where an existing supply is being replaced, and larger multi-room or commercial fit-outs where a second power segment is required to keep the bus within safe current and cable-length limits. Its protective circuitry also gives installers peace of mind that a wiring fault on one part of the system won't take down the entire bus.

Frequently Asked Questions

How many KNX devices can this power supply run?
Following standard KNX bus line rules, a single power supply segment of this type can typically support up to 64 KNX devices, depending on each device's current draw and total cable length.

What is the auxiliary output used for?
The auxiliary terminal supplies a separate 30VDC feed that can power terminal devices directly, keeping that load off the main bus line output.

Can this unit be reset remotely if the bus trips out?
Yes, the module supports a bus reset function so installers can restore power to the line without physically visiting the DIN rail enclosure.
