DPC-120-200

Overview

The Signal Transformer DPC-120-200 is a laminated core power transformer designed for printed circuit board mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz frequencies. The unit provides a secondary output of 120 VCT at 200 mA or 60 V at 400 mA, delivering a total power rating of 24 VA. Constructed with a split bobbin design, it ensures reliable electrical isolation with a dielectric strength of 1500Vrms. The component operates within a temperature range of -40°C to +105°C and utilizes quick connect terminals for efficient assembly.

Feature Summary

• Dual primary winding configuration supports flexible input voltage selection
• Split bobbin construction enhances electrical safety and isolation
• Laminated core design optimizes efficiency for standard frequency applications

Applications

• Industrial control systems requiring PCB-mounted power conversion
• Electronic equipment needing isolated AC power supply stages
• General purpose low-power transformer applications in consumer electronics

Procurement Notes

Verify the specific datasheet version to confirm compliance with current RoHS directives and environmental regulations. Ensure that the selected variant matches the required secondary current and voltage configuration for your circuit design. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability. Confirm that the quick connect terminal type aligns with your assembly process requirements.

Selection Notes

Select this model when a compact, board-mount solution is required for 24 VA power transformation. The dual primary capability allows adaptation to both 115 VAC and 230 VAC mains without changing components. Consider the physical dimensions and quick connect termination style during layout planning. This transformer is suitable for applications demanding Class B insulation and robust thermal performance up to 105°C.

Part Context

The DPC-120-200 belongs to the Signal Transformer series of miniature laminated power transformers. These components are engineered for high reliability in space-constrained environments. The product line emphasizes standardized footprints and consistent electrical characteristics across various power ratings, facilitating easier design reuse and supply chain management for industrial and commercial electronic products.

Replacement Considerations

Direct substitutes may include other 24 VA PCB-mount transformers from Signal Transformer with identical pinouts and electrical ratings. Verify that alternative parts maintain the same 1500Vrms dielectric strength and operating temperature range. Ensure mechanical compatibility regarding length, width, and height constraints before finalizing any replacement strategy.
