241-3-12

Power Transformers Overview

The Signal Transformer 241-3-12 is a laminated core industrial control transformer designed for chassis mounting. It features a split bobbin construction with dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz frequencies. The unit provides a single secondary winding output of 12.6 VCT with a current rating of 200 mA, delivering a power capacity of 2.4 VA. Physical dimensions are 52.6 mm in length, 29.6 mm in width, and 31.2 mm in height. Terminals utilize quick connect end types. The component operates within a temperature range of -40°C to +105°C.

Power Transformers Feature Summary

• Split bobbin construction providing superior electrical isolation and low capacitive coupling between windings
• Dual primary winding configuration allowing flexible voltage selection for 115 VAC or 230 VAC input systems
• Chassis mount design with quick connect terminals for straightforward integration into industrial control panels

Power Transformers Applications

• Industrial control panel power supply circuits
• Equipment requiring isolated low-voltage AC control signals
• General purpose power transformation in machinery operating at 50/60 Hz

Power Transformers Procurement Notes

Verify the specific datasheet version for the 241-3-12 model to confirm terminal pitch and insulation class requirements. Ensure that the receiving facility has appropriate handling procedures for laminated core components due to potential weight and fragility. Cross-reference the quick connect terminal specifications with mating connector availability before finalizing procurement orders to prevent assembly delays.

Power Transformers Selection Notes

Select this component when a compact, low-power (2.4 VA) isolation solution is required for industrial environments. The dual primary capability makes it suitable for global deployment where input voltages may vary between 115 VAC and 230 VAC. Consider the chassis mount style and quick connect termination when designing PCB or wire harness interfaces. Evaluate thermal management needs given the +105°C maximum operating temperature limit.

Power Transformers Part Context

The 241-3-12 belongs to the Signal Transformer 241 series, which utilizes split bobbin technology to enhance safety and performance in industrial applications. This series is characterized by robust laminated cores and standardized footprints. The manufacturer, Bel Signal Transformer, produces these units as part of their broader portfolio of power transformers designed for reliability in demanding operational conditions.

Power Transformers Replacement Considerations

Direct substitutes include models from the same 241 series with matching electrical ratings, such as the DP-241-6-12 for higher power applications or the 241-3-120 for different voltage outputs. Verify that any replacement maintains the same physical dimensions, terminal type, and mounting style to ensure compatibility with existing enclosures.
