DMPC-X-12

Overview

The Signal Transformer DMPC-X-12 is a laminated core power transformer rated at 10VA. It features dual primary windings supporting 115V and 230V inputs, configured for parallel operation. The unit includes dual secondary windings providing 5V (360mA) and 12V (60mA) outputs, also arranged in parallel. Designed for through-hole mounting, it operates at 50/60 Hz with a dielectric strength of 1500Vrms. Physical dimensions are 47.6mm x 36.5mm x 41.3mm.

Feature Summary

• Dual primary winding configuration supports flexible input voltage selection
• Dual secondary windings provide independent regulated output voltages
• Through-hole termination style ensures secure PCB integration
• Class B insulation rating with high dielectric strength

Applications

• General purpose AC to DC power supply modules
• Industrial control system power distribution
• Consumer electronics internal power conversion
• Low-noise SMPS type applications

Procurement Notes

Verify the specific datasheet version from Bel Signal Transformer or authorized distributors to confirm exact pinout configurations and thermal characteristics. Ensure the procurement source provides UL and CSA certification documentation as these approvals are critical for compliance in regulated markets. Cross-reference the part number suffixes to match the required lead-free or RoHS specifications if applicable to your manufacturing process.

Selection Notes

Select this model when dual isolated outputs are required from a single transformer footprint. The 10VA rating suits low-power applications where space constraints favor through-hole mounting over surface mount alternatives. Consider the 1500Vrms isolation barrier for safety-critical designs requiring robust separation between primary and secondary circuits.

Part Context

This component belongs to the Signal Transformer MPC-X series of printed circuit mount power transformers. These units are designed for board-level integration, offering compact encapsulated construction. The series typically supports frequency ranges up to 500Hz without voltage degradation, distinguishing them from standard line-frequency only transformers.

Replacement Considerations

Direct substitutes include other models within the Signal Transformer MPC-X family with matching VA ratings and winding configurations. Verify that replacement parts maintain the same physical envelope dimensions (47.6mm x 36.5mm x 41.3mm) and pin spacing to ensure compatibility with existing PCB layouts.
