The Technical Pro PS9U is a power supply unit designed to provide power to multiple devices, featuring nine individually controllable power outlets and a USB charging port. It is housed in a rack-mountable chassis, making it suitable for professional audio and video setups, as well as other applications requiring organized power distribution.
Function Description:
The primary function of the PS9U is to distribute power to up to nine connected devices. Each of the nine power outlets can be individually switched on or off via corresponding controls on the front panel. This allows users to selectively power on or off specific equipment without affecting others. Additionally, the unit includes a dedicated USB "Charger" port on the front panel, providing 5V power for charging compatible devices via a USB cable. The PS9U acts as a pass-through power supply, meaning the output voltage of its outlets will be the same as the input voltage supplied to the unit. For instance, if the PS9U receives a 110V input, all nine power outlets will supply 110V.
Important Technical Specifications:
- Power Input: 110-240V/AC, allowing for versatile use in different regions or with various power sources.
- Power Output: The voltage of the outlets matches the input voltage. This is a crucial detail for users to ensure compatibility with their connected devices. For example, if a 110V input is used, all connected devices must also be rated for 110V.
- Dimensions: 16.5" (width) x 1.9" (height) x 4.7" (depth). These dimensions suggest a standard 1U rack-mountable form factor, making it easy to integrate into existing equipment racks.
- Fuse: The PS9U includes a 15 Amp replaceable fuse, located just below the power supply. This fuse provides essential overcurrent protection for the unit and connected devices.
- Output Channels: 9 individually switched power outlets.
- Charging Port: 1 x 5V USB "Charger" port.
Usage Features:
- Individual Channel Control: The front panel features nine switches, each corresponding to one of the nine power outlets. This allows for granular control over which devices receive power, enhancing flexibility and energy management.
- USB Charging: The integrated 5V USB charging port offers convenience for powering or charging small electronic devices like smartphones, tablets, or other USB-powered accessories, reducing the need for separate chargers.
- Rack-Mountable Design: Its dimensions and design are optimized for rack installation, providing a neat and organized solution for power distribution in professional environments.
- Voltage Pass-Through: Users must be aware that the output voltage mirrors the input voltage. This design simplifies the internal circuitry but places responsibility on the user to ensure all connected devices are compatible with the supplied input voltage.
- Clear Front Panel Indicators: While not explicitly detailed, the presence of switches for each channel typically implies associated indicator lights (e.g., LEDs) to show the on/off status of each outlet, aiding in quick visual checks.
Maintenance Features:
- Replaceable Fuse: The 15 Amp replaceable fuse is a key maintenance feature. In the event of an overcurrent, the fuse will blow to protect the unit and connected equipment. Users can easily replace this fuse, minimizing downtime and avoiding the need for professional repair for a common issue.
- Cleaning Instructions: The manual specifies cleaning with a dry cloth only, emphasizing the importance of avoiding liquids to prevent electrical shock or damage.
- No User-Serviceable Parts (Internal): The manual explicitly states, "DO NOT REMOVE THE COVER OF THIS UNIT. THERE ARE NO USER-SERVICEABLE PARTS INSIDE. REFER ALL SERVICING TO A QUALIFIED TECHNICIAN." This is a critical safety and maintenance instruction, indicating that internal repairs or modifications should only be performed by qualified personnel to prevent electric shock and ensure proper functioning.
- Environmental Precautions: Warnings against exposure to extreme temperatures, humid areas, rain, or moisture are provided to ensure the longevity and safe operation of the device. Avoiding heat sources like radiators, stoves, or other amplifiers is also advised.
- Cable Management and Protection: Users are instructed to protect all connected wires from being walked on or pinched, especially at the plugs and where they exit the unit. This helps prevent damage to cables, which can lead to electrical hazards or equipment malfunction.
- Grounding: Proper grounding of the unit is emphasized to ensure safety and prevent electrical hazards.
- Power-Off During Storms/Long Periods of Disuse: Unplugging the unit during lightning storms or when unused for long periods is recommended to protect it from potential damage due to power surges or other electrical issues.
The PS9U is designed with both functionality and safety in mind, providing a reliable power distribution solution for various applications while emphasizing user responsibility for proper installation, operation, and adherence to safety guidelines.
