Overview
The DPC-34-300 is a laminated core power transformer from the Signal Transformer DPC series, designed for through-hole mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation. The secondary configuration provides dual outputs: 34 VCT at 300 mA in series mode, or 17 V at 600 mA in parallel mode. With a power rating of 10 VA, the unit measures 47.6 mm in length, 36.5 mm in width, and has a height consistent with standard board-mount transformers.
Feature Summary
- Dual primary winding capability supports global voltage compatibility across 115 VAC and 230 VAC inputs.
- Flexible secondary output allows selection between series (34 VCT) or parallel (17 V) configurations to match circuit requirements.
- Laminated core construction ensures efficient magnetic coupling and stable performance under load.
Applications
- Power supply units requiring isolated AC voltage transformation
- Industrial control systems utilizing dual-voltage secondary outputs
- Equipment needing flexible secondary current ratings via series/parallel switching
Procurement Notes
Verify that the specific order matches the DPC-34-300 designation to ensure correct secondary current ratings. Confirm that the receiving facility accepts through-hole components, as surface-mount variants are not applicable. Check datasheet specifications for thermal limits and insulation class before integration into final assemblies.
Selection Notes
Choose this model when a 10 VA rating is sufficient and dual secondary flexibility is required. Compare against the DPC-34-125 if lower current capacity is acceptable. Ensure the PCB layout accommodates the specified lead spacing and physical dimensions for proper mechanical retention.
Part Context
This component belongs to the DPC series of general-purpose power transformers manufactured by Signal Transformer. The series offers various power ratings and voltage combinations, with the DPC-34-300 representing a mid-range option balancing size and output capability for standard industrial applications.
Replacement Considerations
The DPC-34-125 serves as a verified substitute within the same series, offering identical form factor but reduced secondary current ratings. Verify that the application can tolerate the lower 125 mA/250 mA output before swapping.
