Overview
The Signal Transformer DPC-10-90 is a miniature laminated core power transformer designed for printed circuit board mounting. It features dual primary windings supporting 115V and 230V parallel operation, providing versatile input compatibility. The secondary configuration offers parallel output at 5V with 180mA current rating, or series output at 10V with 90mA current rating. This component delivers a rated power capacity of 1VA, ensuring efficient energy conversion for low-power applications while maintaining electrical isolation.
Feature Summary
- Miniature form factor optimized for direct printed circuit board integration
- Dual primary winding architecture enabling flexible voltage selection
- Configurable secondary outputs supporting both parallel and series connections
Applications
- Industrial control panels and relay circuits
- Alarm system power supplies and notification circuits
- Instrumentation and measurement devices
Procurement Notes
Verify the specific datasheet version to confirm insulation class ratings and thermal characteristics. Ensure that the selected mounting orientation aligns with the specified lead dimensions. Cross-reference the secondary voltage configuration requirements against the available parallel and series options before finalizing the order to prevent functional mismatches in the target assembly.
Selection Notes
Select this component when space constraints require a compact transformer solution for PCB-mounted designs. Evaluate the 1VA power limit against the total load requirements of the downstream circuitry. Consider the dual primary flexibility if the equipment operates in regions with varying standard mains voltages without requiring separate part numbers.
Part Context
This model belongs to the low-power transformer category from Signal Transformer, specifically engineered for servo power and general-purpose industrial applications. It complements larger chassis-mount units by offering a surface-integrated alternative for smaller electronic enclosures where volume is a critical design parameter.
Replacement Considerations
No public confirmed substitute part numbers are documented.
