The Patton replacement power supply PS-03671H1-013 is an external AC/DC power supply for SmartNode devices, specifically designed as a replacement for the power supply components included in the scope of delivery of certain models. It provides power for VoIP gateways and other network devices in the SmartNode series that operate with an external power supply. The device delivers a constant DC voltage of 12 volts at a maximum current of 3 amperes, corresponding to a maximum power output of 36 watts. These specifications are important for the operational safety and stability of the connected devices, as insufficient or unstable power supply can lead to malfunctions or failures.

Applications
This power supply is intended for a variety of Patton SmartNode models, including the series SN463X, SN465X, SN466X, SN467X, SN483X, SN497X, SN498X, and SN4991. These devices are typically used in network infrastructures supporting VoIP telephony, data transmission, or other IP-based services.

Functions and Features in Detail
The power supply features a universal input (UNIV IN), enabling broad voltage range compatibility for use in various countries and networks. The input voltage may vary depending on regional mains voltage, with the device designed for AC power supply. The output voltage is 12 volts DC, delivered via a fixed connector. The maximum output power of 36 watts is sufficient to meet the power requirements of the specified SmartNode models. The maximum operating temperature is 40 degrees Celsius, covering typical indoor operating conditions with normal ambient temperature.

Technology Explained Simply
The AC/DC power supply converts alternating current from the mains into a constant direct current required by the internal electronic components of SmartNode devices. The designation UNIV IN means the device is compatible with a wide range of input voltages, facilitating use in different regions. The output voltage of 12 V and current of 3 A are specifically designed for the connected devices to ensure operational safety. The maximum power of 36 W indicates the energy the power supply can deliver, corresponding to the sum of the power consumption values of the connected devices.

Compatibility and Accessories
The power supply is specifically designed for Patton SmartNode models SN463X, SN465X, SN466X, SN467X, SN483X, SN497X, SN498X, and SN4991, which are equipped with an external power supply. It is not intended for models that feature an internal power supply.

Mounting and Installation
The power supply is designed as a desktop model, meaning it can be placed on a flat surface, such as a desk or in a rack. Installation involves connecting the power supply to the mains and then connecting the output cable to the SmartNode device. There are no special mounting instructions or tools required for installation, as the device is designed as a standard power supply.

Operational Advantages
Using this replacement power supply allows defective or worn-out power supply components to be replaced without replacing the main device. This reduces operating costs and extends the service life of SmartNode devices. The universal input voltage enables flexible use in various locations, and the constant output voltage ensures stable power supply, which is crucial for the reliability of network devices. The maximum operating temperature of 40 °C ensures safe operation under normal indoor conditions.
