Overview
The DP-241-5-48 is a laminated core industrial control transformer with a split bobbin construction. It features dual primary windings rated for 115 VAC and 230 VAC, providing versatile input compatibility. The single secondary winding delivers 48 VCT at a maximum current of 0.25 A, resulting in a power rating of 12 VA. Designed for chassis mounting, it utilizes screw terminals for secure electrical connections. The unit operates within a temperature range of -40°C to +105°C at standard frequencies of 50 Hz or 60 Hz.
Feature Summary
- Split bobbin design ensures superior isolation and low capacitive coupling between windings
- Dual primary winding configuration supports both 115 VAC and 230 VAC input voltages
- Chassis mount style facilitates stable installation in industrial control enclosures
Applications
- Industrial control panel power supply circuits
- Servo system power distribution
- Equipment requiring isolated 48V control voltage
Procurement Notes
Verify the specific suffix against official Signal Transformer documentation to confirm terminal type and insulation class. Confirm that the 12 VA rating aligns with the load requirements of the target application. Ensure chassis mounting dimensions match the enclosure constraints. Cross-reference the datasheet revision date to guarantee compliance with current safety standards.
Selection Notes
Select this model when a compact, isolated 48VCT source is required for industrial environments. The split bobbin architecture is critical for applications demanding high noise immunity and strict isolation barriers. Verify that the 0.25 A output current capacity meets the peak demand of the connected control circuitry without exceeding thermal limits.
Part Context
This component belongs to the DP-241 series of two-for-one transformers manufactured by Signal Transformer. The series utilizes laminated cores optimized for 50/60 Hz operation. The DP-241-5-48 variant specifically targets applications needing a 48V center-tapped output derived from standard line voltages, fitting within the broader portfolio of industrial-grade power conversion solutions.
Replacement Considerations
Consult official manufacturer substitution guides for direct equivalents. Generic replacements may lack the specific split bobbin isolation characteristics. Verify that any substitute part matches the 12 VA rating, 48 VCT output, and chassis mounting footprint to ensure mechanical and electrical compatibility.
