Product Information

Full details

The VEMER VN311700 Safety Transformer (Model TMD 10/24) is designed for industrial and automation applications requiring a stable, isolated power source, particularly for discontinuous service. Its key benefit is providing a reliable 10VA power output with adjustable secondary voltages from 12-24V AC, fitting neatly into a 2 DIN module space. A caveat to consider is its suitability for discontinuous service, meaning it is not intended for continuous, full-load operation.

Extended Product Information

FAQs

What does 'discontinuous service' mean for this transformer?

Discontinuous service means the transformer is designed for applications where it is not continuously energized or operating at full load. It is suitable for intermittent use, such as in control systems that cycle on and off.

How do I select the secondary voltage (12V or 24V)?

The secondary voltage selection is typically made via internal jumpers or terminal block configurations. Refer to the VEMER VN311700 product manual for specific instructions on how to set the desired voltage.

Is this transformer suitable for continuous operation?

No, this transformer is specifically rated for discontinuous service and is not intended for continuous, full-load operation. Prolonged continuous use may lead to overheating and reduced lifespan.

What is the power rating of this transformer?

The transformer has a power rating of 10VA (Volt-Amperes).

What size DIN module does it occupy?

This transformer occupies 2 DIN modules, making it a compact solution for control panels.

What is the primary voltage input?

The primary voltage input for this transformer is 230V AC.

Does this transformer provide galvanic isolation?

Yes, as a safety transformer, it provides galvanic isolation between the primary and secondary circuits, enhancing electrical safety.

Troubleshooting

No output voltage

Verify primary voltage supply (230V AC). Check wiring connections at both primary and secondary terminals. Ensure the secondary voltage setting is correctly configured.

Low output voltage

Confirm the load does not exceed the 10VA rating. Check for loose connections. Ensure the selected secondary voltage corresponds to the transformer's setting.

Overheating

Ensure the transformer is not used for continuous service or is overloaded. Verify adequate ventilation around the unit. Check for short circuits in the connected load.

Intermittent operation

Check for unstable primary voltage. Ensure the load is within the transformer's discontinuous service capacity. Inspect connections for intermittent faults.

Pros and Cons

Pros

  • Compact and space-saving design (2 DIN modules).
  • Adjustable output voltage (12-24V AC) for versatile application.
  • Reliable power delivery for control and instrumentation.
  • Easy installation on standard DIN rails.
  • Manufactured in Italy, suggesting adherence to quality standards.

Cons

  • Rated for discontinuous service only, not continuous operation.
  • 10VA power rating may be insufficient for higher-demand applications.
  • Requires manual adjustment of secondary voltage via internal settings.
  • Does not include built-in overload protection; external protection is necessary.

Setup, Compatibility & Care

Setup:

  1. Ensure the primary voltage source is switched off.
  2. Mount the transformer onto a standard 35mm DIN rail.
  3. Connect the primary wiring to the appropriate input terminals (230V AC).
  4. Select the desired secondary voltage (12V AC or 24V AC) by adjusting the internal jumper or terminal connections as per the product manual.
  5. Connect the secondary wiring to the load.
  6. Restore power and verify output voltage.

Compatibility:

  • Compatible with standard 230V AC mains power.
  • Suitable for use with devices requiring 12V AC or 24V AC up to 10VA.
  • Designed for integration into control cabinets and electrical enclosures with DIN rail mounting.

Care:

  • Keep ventilation slots clear of dust and obstructions.
  • Periodically check wiring connections for tightness and signs of wear.
  • Clean the exterior with a dry or slightly damp cloth; avoid solvents.
  • Ensure the transformer operates within its specified temperature range and load limits.
