Allen Bradley 1497-F-BASX-3-N 1497 Series Control Circuit Transformer

Product Overview

The Allen Bradley 1497-F-BASX-3-N provides stable, stepped-down voltage for industrial control circuits, ensuring the safe operation of electromagnetic devices like contactors, relays, and timers. This 350 VA transformer isolates the control logic from the high-voltage main supply, reducing electrical noise and protecting sensitive components. We supply this unit as 100% Brand New original stock, delivering factory-calibrated voltage accuracy for critical motor control centers and machine tool applications.

Technical Specifications

The 1497-F-BASX-3-N features multi-voltage primary taps to accommodate diverse global power standards within a single footprint.

Engineering Advantages

• Superior Voltage Regulation: This transformer maintains precise output voltage even during high-inrush conditions, such as when multiple motor starters energize simultaneously. This prevents "chatter" in relays and ensures the control circuit remains stable under fluctuating loads.

• Dual-Frequency Versatility: The 1497-F-BASX-3-N operates efficiently at both 50Hz and 60Hz. This capability allows OEMs to standardize their panel designs for international export, as the unit adapts to varying regional utility frequencies without requiring hardware changes.

• High-Integrity Insulation: The core and coil utilize high-grade insulation materials that resist thermal degradation. This design withstands the localized heat generated during continuous duty cycles in unventilated control cabinets.

• Rugged Mechanical Construction: At nearly 14 lbs, the unit features heavy-duty mounting feet and vacuum-impregnated windings. This construction dampens audible humming and protects the internal copper coils from the structural vibrations common in heavy industrial machinery.

FAQs

• How do I configure the transformer for 480V primary input?

  Connect the primary jumpers according to the wiring diagram on the nameplate. For 480V operation, you typically wire the primary coils in series. Always verify the terminal markings before applying power to prevent winding damage.

• Does this unit include integrated primary and secondary fusing?

  This specific configuration (Suffix -N) determines the factory-installed fuse block options. While most 1497 series units support optional finger-safe fuse covers and blocks, verify your specific enclosure requirements to ensure compliance with local electrical codes for branch circuit protection.

• Can I use this transformer to power DC power supplies?

  Yes. Many engineers use the 120V secondary to feed AC-to-DC switch-mode power supplies. The transformer provides an additional layer of galvanic isolation, shielding the DC electronics from high-voltage spikes on the main line.

• What is the maximum ambient temperature for the 1497-F-BASX-3-N?

  Standard industrial transformers of this class operate reliably in ambient temperatures up to 40°C (104°F) without derating. If your cabinet internal temperature exceeds this, ensure adequate ventilation or choose a higher VA rated unit to compensate for thermal loss.
