FMX Control Transformers

Control Transformers
FMX Control Transformers are utilized to change one voltage to another and are typically installed within a control panel or electrical enclosure. Models are available from 45 to 5000VA. Primary voltages range from 120 to 600V with secondary voltages ranging from 24 to 240V. FMX control transformer accessories include fuse blocks, replacement fuse clips and fuses, and safety covers for fuse blocks and fuse clips.

CERTIFICATIONS


STANDARD - UL Listed



  • • FMX transformers are by default UL Listed for use in both the US and Canada.
  • • UL transformers are built to the exacting standards of UL fire safety. They meet all requirements for a safe installation within a panel.

SPECIAL ORDER - CE CERTIFIED



  • • All FMX transformers can be ordered with optional CE certification in place of UL. Transformers marked as CE are generally intended for export markets.
  • • CE transformers use a different bobbin material and insulation to meet European fire standards.
  • • Minimum quantities apply, please call for more details.

TRANSFORMER SELECTION PROCESS

Transformer selection requires the following specifications:
  • Inrush VA - The product of the load voltage multiplied by the current required during startup. The table to the right shows the maximum available inrush VA for each transformer size.
  • Sealed VA - Also called “steady-state VA” and is the load voltage multiplied by the current required during normal operating conditions.
  • Primary Voltage - The voltage available from the distribution source and connected to the primary transformer terminals. .
  • Secondary Voltage - The voltage required by the load. Will be connected to the secondary transformer terminals.
