Extended Product Information

FAQs

Can this power supply be mounted vertically?

No, for optimal cooling and performance, this power supply must be mounted horizontally to utilize natural convection.

What is the maximum output current?

The maximum output current for a single WAGO 2687-2142 unit is 1.25A. For higher current requirements, multiple units can be connected in parallel.

What does the DC-OK LED indicate?

The green DC-OK LED indicates that the power supply is operating correctly and providing a stable DC output voltage within its specified range.

What is the input voltage range?

The input voltage range is 90 - 264V AC, suitable for worldwide single-phase power grids.

Is the output voltage adjustable?

Yes, the output voltage is adjustable within a range of 22V to 29V DC.

What is the IP rating?

The International Protection (IP) code is IP20, meaning it is protected against solid objects larger than 12.5mm but offers no protection against water.

Can I use this in a series configuration?

Yes, the unit is suitable for series operations, which can be used to achieve higher output voltages, depending on the specific application requirements.

Troubleshooting

Unit does not power on / No output voltage

Verify AC input voltage is within the 90-264V range. Check all input and output connections for proper seating. Ensure the output is not short-circuited.

DC-OK LED is not lit

Check AC input power. Verify the output voltage is within the specified range (22-29V). Ensure the load is connected correctly and not exceeding the 1.25A limit. If the problem persists, there may be an internal fault.

Overheating

Ensure the unit is mounted horizontally to allow for natural convection cooling. Check that ventilation slots are not blocked by dust or other obstructions. Verify that the connected load does not exceed the 1.25A output current rating.

Output voltage is unstable

Check input voltage stability. Ensure connections are secure. If the output voltage is adjusted, try resetting it to a nominal value and re-adjusting carefully.

Pros and Cons

Pros

  • Versatile for parallel and series configurations
  • Adjustable output voltage offers precision
  • Built-in safety features with electrical isolation
  • Easy status monitoring with optical indicator
  • Tool-free installation and operation
  • Compact design suitable for DIN-rail mounting

Cons

  • Requires horizontal mounting for effective cooling
  • Limited to single-phase input
  • IP20 rating means it's not suitable for wet or dusty environments without further protection
  • Output current is fixed at 1.25A per unit, requiring parallel configuration for higher demands
  • No active cooling (fan), relies solely on passive convection

Setup, Compatibility & Care

Setup:

  1. Mount the power supply horizontally on a 35mm DIN-rail using the integrated clip. Ensure adequate ventilation space around the unit.
  2. Connect the AC input voltage (90-264V) to the designated terminals. Ensure compliance with local electrical codes.
  3. Connect the DC output terminals to your load. The voltage can be adjusted via the output adjustment screw within the 22-29V range before connecting the load, or while connected if the load does not draw excessive current.
  4. Verify the DC-OK LED is illuminated green once power is applied.

Compatibility:

  • Input Voltage: Compatible with standard AC input voltages from 90V to 264V, covering single-phase power grids worldwide.
  • Output: Provides a stable 24VDC output (adjustable 22-29V) with a maximum of 1.25A. Ensure your connected devices do not exceed these specifications.
  • Mounting: Designed for standard 35mm DIN-rail mounting.

Care:

  • The unit requires minimal care due to its fanless design. Ensure the ventilation slots are kept clear of dust and debris. A soft brush or compressed air can be used periodically.
  • Avoid exposing the unit to moisture, corrosive substances, or extreme temperatures outside its operating range (-25°C to 70°C).
