KNX Power Supply PS164 (640 mA) | Professional Bus Power Unit

Name: Panasonic KNX Power Supply 640 mA
Brand: Panasonic
SKU: knx-power-supply-ps164-640ma
Price: 138.00 EUR
Availability: InStock

The KNX Power Supply PS164 is a critical system component designed to provide a stable and reliable 30V DC bus voltage for a KNX line. With a 640 mA current rating, it is the industry-standard “workhorse” for powering a single KNX line, typically supporting up to 64 devices (depending on the specific power consumption of individual bus participants). Utilizing a high-quality KNX Power Supply PS164 ensures data integrity and prevents system resets due to voltage drops.

Core Specifications & Hardware Features

The PS164 640mA power supply is engineered for durability and efficiency in professional building automation environments.

Output Current: 640 mA (Regulated) for full-line support.
Bus Voltage: 30V DC (+1/-2 V) with an integrated choke to prevent data signal interference.
Auxiliary Output: Includes an additional 30V DC output (without choke) to power high-consumption devices like IP routers, displays, or logic modules without using a second power supply.
Protection: Fully protected against short circuits, overloads, and overheating to ensure maximum system uptime.
Mounting: Compact DIN-rail design (4 modules wide) for easy integration into electrical distribution boards.

Key Technical Advantages

Feature	Technical Benefit
Integrated Choke	Decouples the power supply from the communication signal, allowing data telegrams to travel across the bus without being absorbed by the power source.
Status LEDs	Front-facing indicators for Power (Run), Overload (I > Imax), and Reset, allowing for instant on-site diagnostics.
Wide Input Range	Designed to handle AC input variations (typically 100V–240V AC), making it suitable for global electrical standards.
Reset Function	A dedicated reset button/switch allows for a localized bus restart without disconnecting wires physically.

Installation & Wiring Guidelines

To ensure the longevity of your KNX Power Supply PS164 and the reliability of the EAE KNX or other connected actuators, follow these wiring standards:

Bus Connection: The red (+) and black (-) bus wires must be connected to the “KNX Bus” output. Ensure the cable is a certified KNX twisted-pair (green) cable.
Auxiliary Use: If your project uses a KNX IP Router or a Touch Panel, use the auxiliary output (Yellow/White) to save space and cost on additional power sources.
Loading: While a 640 mA supply can theoretically power 64 devices, it is best practice to calculate the total current draw (usually ~10mA per device) and leave a 20% safety margin for peak communication loads.

Frequently Asked Questions (FAQ)

Q: Can I use the PS164 with the EAE RCU2000 KNX ACTUATOR?
A: Yes, the PS164 provides the necessary bus power and choke required for the EAE RCU2000 KNX ACTUATOR to communicate reliably across the network.

Q: What happens if the PS164 is overloaded?
A: The “Overload” LED will illuminate, and the device will automatically protect the circuit by limiting the current or shutting down temporarily until the load is reduced.
