1. Introducció

This manual provides instructions for the installation, operation, and maintenance of the Functional Devices (RIB) PSH100A Enclosed Single 100VA 120 to 24Vac UL Class 2 Power Supply. The PSH100A is designed to convert 120 Vac input power to a stable 24 Vac output, suitable for various low-voltage applications requiring a UL Class 2 power source.

Si us plau, llegiu aquest manual detingudament abans de la instal·lació i el funcionament per garantir un ús segur i eficient del producte.

2. Informació de seguretat

ADVERTÈNCIA: Risc de descàrrega elèctrica. Desconnecteu l'alimentació abans de la instal·lació o el manteniment.

• La instal·lació i el manteniment només els ha de dur a terme personal qualificat.
• Compliu tots els codis elèctrics nacionals i locals.
• No excedeixi el vol especificattage i les classificacions actuals del dispositiu.
• Assegureu-vos d'una connexió a terra adequada on calgui.
• No feu funcionar el dispositiu si sembla que està danyat.

3. Configuració i instal·lació

The PSH100A power supply is housed in a metal enclosure for protection and ease of mounting.

3.1. Muntatge

The enclosure is designed for surface mounting. Select a suitable location that is dry, well-ventilated, and accessible for wiring and inspection. Use appropriate fasteners (not included) to secure the enclosure to a wall or panel through the pre-drilled mounting holes.

3.2. Cablatge

Ensure all power is disconnected at the circuit breaker before proceeding with wiring.

1. Open the enclosure cover to access the terminal block.
2. Input Wiring (120 Vac): Connect the 120 Vac line voltage to the designated input terminals. Typically, these are marked "L" (Line) and "N" (Neutral) or similar. Ensure proper polarity.
3. Output Wiring (24 Vac): Connect the load requiring 24 Vac to the designated output terminals. These are usually marked "24VAC" or similar.
4. Posada a terra: Connect the system ground to the grounding terminal within the enclosure, if provided and required by local codes.
5. Verify all connections are secure and correct.
6. Tanqueu la coberta del recinte.

4. Instruccions de funcionament

Once the PSH100A power supply is correctly installed and wired, restore power to the circuit. The unit will immediately begin providing 24 Vac power at its output terminals. The PSH100A is designed for continuous operation and does not require any user interaction during normal use.

• The power supply is a Class 2 device, meaning its output is inherently limited to prevent electric shock and fire hazards.
• Ensure the connected load does not exceed the 100 VA (Volt-Ampere) rating of the power supply.

5. Manteniment

The PSH100A power supply is generally maintenance-free. However, periodic inspection is recommended to ensure optimal performance and safety.

• Inspecció anual: Visually inspect the enclosure for any signs of physical damage, corrosion, or overheating.
• Comprovació del cablejat: With power disconnected, verify that all wiring connections remain tight and secure.
• Neteja: If necessary, gently clean the exterior of the enclosure with a dry, soft cloth. Do not use liquid cleaners or solvents.

WARNING: Do not attempt to open or repair the internal components of the power supply. Refer all servicing to qualified personnel.

6. Solució De Problemes

If the PSH100A power supply is not functioning as expected, refer to the following troubleshooting steps:

• Sense Vol de sortidatage:
  • Verify that the 120 Vac input power is present at the input terminals using a multimeter.
  • Check the circuit breaker supplying power to the unit.
  • Inspeccioneu totes les connexions del cablejat per detectar si hi ha fluïdesa o danys.
  • Ensure the load connected to the output is not short-circuited or drawing excessive current, which could trigger internal protection.
• Sobreescalfament:
  • Ensure the power supply is installed in a location with adequate ventilation.
  • Verify that the connected load does not exceed the 100 VA rating of the power supply. Excessive load can cause overheating.

If the issue persists after performing these steps, contact Functional Devices, Inc. technical support.
