DP-241-6-20

Overview

The Signal Transformer DP-241-6-20 is a single-phase industrial power transformer with a 30 VA rating. It features dual primary windings supporting 115 VAC and 230 VAC inputs, paired with a single secondary winding providing 20 VCT at 1.5 A. The unit utilizes a split bobbin construction for enhanced isolation and low capacitive coupling. Designed for chassis mounting, it employs quick connect or solder termination styles. Operating within a temperature range of -40°C to +105°C at 50/60 Hz, the transformer measures 82.6 mm in length, 44.3 mm in width, and 49.8 mm in height, weighing approximately 500 g.

Feature Summary

• Split bobbin design ensures superior electrical isolation and minimizes capacitive coupling between windings.

Applications

• Industrial control systems requiring isolated power conversion
• Chassis-mounted equipment needing standardized voltage transformation
• Servo power supplies utilizing center-tapped secondary outputs

Procurement Notes

Verify that the specific order matches the DP-241-6-20 designation to ensure correct voltage ratings and physical dimensions. Confirm termination preferences, as this model supports both quick connect and solder options depending on configuration. Check datasheet specifications for dielectric strength and thermal limits before integration into final assemblies to guarantee compliance with operational requirements.

Selection Notes

Select this component when a 30 VA capacity is required for converting standard line voltages to a 20 VCT output. The dual primary winding capability allows flexibility for different input regions without changing hardware. Ensure the application environment stays within the specified temperature range and that chassis mounting provisions align with the mechanical footprint constraints of the target enclosure design.
