Overview
The DPC-34-125 is a laminated core power transformer designed for through-hole PCB mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50/60 Hz. The secondary configuration offers a center-tapped 34 V output at 125 mA in series mode, or a parallel 17 V output at 250 mA. With a 4.4 VA power rating, the unit measures 41.3 mm in length, 31.8 mm in width, and 34.92 mm in height.
Feature Summary
- Dual primary winding capability supporting both 115 VAC and 230 VAC input voltages
- Configurable secondary outputs allowing selection between series 34VCT or parallel 17V configurations
- Laminated core construction optimized for standard 50/60 Hz operating frequencies
Applications
- General purpose AC to DC power supply circuits
- Industrial control panel power distribution
- Servo system auxiliary power stages
Procurement Notes
Verify the specific datasheet version from Signal Transformer or authorized distributors to confirm insulation class and regulatory compliance status such as UL or CE markings. Ensure the selected variant matches the required lead-free RoHS specifications for your assembly process. Cross-reference pinout diagrams with your PCB footprint design to prevent installation errors during manufacturing.
Selection Notes
Select this component when a compact 4.4 VA isolation transformer is required for board-mounted applications. The dual primary design simplifies global voltage compatibility without requiring separate part numbers for different regions. Consider the physical dimensions of 41.3 x 31.8 x 34.92 mm to ensure adequate clearance within the target enclosure structure.
Part Context
This model belongs to the DPC series of laminated core transformers manufactured by Signal Transformer. The series is characterized by robust through-hole construction suitable for high-reliability industrial environments. These units typically serve as primary isolation stages in linear power supplies where low noise and stable voltage regulation are critical requirements.
Replacement Considerations
Consult official cross-reference lists for direct equivalents. Verify that any substitute maintains identical electrical ratings including 4.4 VA capacity and compatible terminal spacing.
