Extended Product Information

FAQs

What is the primary application for this power supply?

This power supply is primarily designed for KNX building automation systems and other industrial applications requiring a stable 30V DC output at 640mA.

Can the output voltage be adjusted?

No, the output voltage is fixed at 30V DC and is not adjustable.

What is the maximum input voltage range?

The unit accepts a wide input range of 85-264V AC (at 50/60 Hz) or 90-275V DC.

Is this power supply suitable for outdoor use?

No, it has an IP20 protection rating, making it suitable only for dry, indoor environments. It must be protected from moisture and dust.

What is the total power output capacity?

The total power output capacity is 19.2 Watts.

Does it support DIN rail mounting?

Yes, it is designed for easy mounting on standard 35mm DIN rails.

What is the warranty period?

Please refer to the official Phoenix Contact product documentation or your supplier for specific warranty information, as it can vary by region and reseller.

Troubleshooting

Unit does not power on

Verify input voltage is within the 85-264V AC or 90-275V DC range and that connections are secure. Check for blown fuses in the primary circuit if applicable.

Output voltage is unstable or low

Ensure the connected load does not exceed the 640mA (19.2W) limit. Check input voltage stability. If the issue persists, the unit may require replacement.

Overheating

Ensure adequate ventilation around the unit and that it is not overloaded. Check for obstructions blocking airflow. Verify operating temperature is within limits.

Short circuit protection tripped

Disconnect the load and identify the cause of the short circuit. Rectify the issue in the load circuit before reconnecting power.

Pros and Cons

Pros

Reliable and stable DC output for sensitive electronics.
Compact form factor ideal for space-constrained enclosures.
Wide input voltage range (AC/DC) offers installation flexibility.
Robust short-circuit protection enhances safety and device longevity.
Easy integration into standard DIN rail mounting systems.

Cons

Fixed output voltage cannot be adjusted.
Maximum output current of 640mA may be insufficient for higher-power applications.
IP20 protection rating means it's suitable for dry, indoor environments only.
Not designed for safety-critical functions requiring specific SIL or PL ratings.

Setup, Compatibility & Care

Setup:

Mounting: Securely attach the unit to a standard DIN rail (35mm) using the integrated mounting clip. Ensure adequate ventilation space around the unit.
Wiring: Connect the AC or DC input voltage to the appropriate terminals (rated 85-264V AC or 90-275V DC). Connect the 30V DC output to your load.
Verification: Before applying power, double-check all connections for correctness and security.

Compatibility:

Input: Compatible with standard AC mains voltage (85-264V AC, 50/60 Hz) and a wide range of DC input voltages (90-275V DC).
Output: Designed for loads requiring 30V DC and a maximum of 640mA (19.2W). Primarily suited for KNX systems and other industrial electronics operating at this voltage.
Mounting: Fits standard 35mm DIN rails. Can also be mounted directly to a wall using appropriate hardware (sold separately).

Care:

Cleaning: Disconnect all power sources before cleaning. Wipe the exterior with a dry or slightly damp cloth. Avoid using solvents or abrasive cleaners.
Environment: Operate within the specified temperature range of -10°C to 70°C. Ensure the IP20 rated unit is protected from dust, moisture, and corrosive substances.
