DP-241-6-28L

Power Transformers Overview

The DP-241-6-28L is a laminated core industrial control transformer manufactured by Signal Transformer. It features a dual primary winding rated for 115 VAC and 230 VAC, providing versatility for global power standards. The single secondary winding delivers 28 VCT at a current rating of 1.1 A, with a total power capacity of 30 VA. Designed for chassis mounting, the unit utilizes screw-type terminal connections for secure electrical interfacing. Physical dimensions are 82.6 mm in length, 44.3 mm in width, and 49.8 mm in height. The component operates within a temperature range of -40°C to +105°C and supports frequencies of 50 Hz and 60 Hz.

Power Transformers Feature Summary

• Dual primary winding configuration allows operation at both 115 VAC and 230 VAC input voltages.
• Chassis mount design with screw terminals ensures stable mechanical installation and reliable connectivity.
• Split bobbin construction provides enhanced isolation between primary and secondary windings.

Power Transformers Applications

• Industrial control panels requiring isolated low-voltage power supplies
• Equipment utilizing 28 VAC control circuits
• General purpose power transformation in commercial machinery

Power Transformers Procurement Notes

Verify that the specific order matches the DP-241-6-28L designation to ensure correct secondary voltage output. Confirm that the application environment remains within the specified operating temperature limits of -40°C to +105°C. Ensure the mounting infrastructure supports the chassis style and physical dimensions provided. Check that the load current does not exceed the 1.1 A rating to maintain safe thermal performance.

Power Transformers Selection Notes

Select this model when a 30 VA power rating is required for systems operating on standard 50/60 Hz frequencies. Choose this variant over other series members specifically for its 28 VCT secondary output capability. Consider the chassis mounting requirement and screw terminal interface when designing the enclosure layout. Verify compatibility with existing dual-primary input sources before finalizing the design.

Power Transformers Part Context

This component belongs to the DP-241 series of industrial control transformers from Signal Transformer. The series is characterized by split bobbin construction and robust laminated cores designed for durability in demanding environments. These transformers are engineered to provide reliable isolation and voltage conversion for various industrial applications requiring standardized power distribution.

Power Transformers Replacement Considerations

The DP-241-6-28L may be replaced by other models within the DP-241 series if different secondary voltages or current ratings are needed. Ensure any substitute maintains the same 30 VA power rating and chassis mounting footprint. Verify that alternative parts support the required 115/230 VAC dual primary inputs and 50/60 Hz frequency operation.
