Control & Buck-Boost Transformer RFQ Intake

This form is built for industrial facilities, commercial buildings, electrical contractors, panel shops, OEM machine builders, EPC firms, and maintenance teams sourcing control power transformers, buck-boost voltage correctors, and small auto-transformers.

  • Control power transformers: VA rating, primary and secondary voltage, mounting style, UL 508 / CSA certification
  • Buck-boost transformers: input and output voltage, correction range, single or three-phase, separately enclosed
  • Auto-transformers: step-up or step-down ratio, kVA, phase, enclosure, and voltage conversion application
  • Standards, certifications, fusing, panel approvals, delivery, and commercial scope

For Control Panel and MCC Applications

Capture VA rating, primary voltage (480V, 600V, 240V), secondary voltage (120V, 24V), panel-mount or chassis-mount, fusing requirements, and UL 508 listing for motor control center and switchgear control circuit transformers.

For Voltage Correction and Conversion

Support buck-boost transformers that adjust line voltage by up to 20%, single and three-phase auto-transformers for generator-to-utility step-up, and international equipment voltage conversion from 480V to 208V or 208V to 240V.

For Machine Builders and Contractors

Collect mounting dimensions, DIN rail requirements, screw or push-in terminal preferences, UL 508A panel shop approval needs, and delivery timelines for machine tool and OEM transformer applications.

Electrical Transformers

1. Transformer Type

Select the transformer type that matches your application. Control power transformers (CPTs) are rated in VA and supply 120V control circuits. Buck-boost transformers correct line voltage by a small percentage. Auto-transformers change voltage without electrical isolation.

Transformer Type

2. Application and Installation Context

Identify where and how the transformer will be used. Control power transformers are commonly mounted inside panels, MCCs, and enclosures. Buck-boost and auto-transformers are often separately enclosed or mounted adjacent to the load.

Primary Application

3. Electrical Ratings and Voltage Requirements

Provide voltage and power rating details. Control power transformers are rated in VA (volt-amperes), not kVA. Buck-boost transformers are specified by the input voltage, the required output voltage, and the kVA of the load they serve.

Ratings and Voltage Data Needed
Buck-Boost / Voltage Correction Data

4. Mounting, Enclosure, and Physical Requirements

Specify mounting configuration and physical requirements. Control power transformers are frequently chassis-mounted inside existing enclosures. Buck-boost and auto-transformers may be separately enclosed or wall-mounted.

Mounting and Enclosure

5. Standards, Certifications, and Approval Requirements

Control power transformers used in industrial control panels are subject to UL 508 / CSA C22.2 No. 14 requirements. Select applicable standards, certifications, and approval needs.

Standards / Certifications / Documentation

6. Implementation, Support, Warranty, and Commercial Scope

Identify delivery, installation, startup, training, support, and commercial requirements.

Commercial Scope

7. Contact, Delivery, Uploads, and Notes
