Overview
The DPC-56-80 is a single-phase power transformer manufactured by Signal Transformer. It features dual primary windings rated for 115 VAC and 230 VAC input, supporting operation at frequencies between 50 Hz and 500 Hz. The unit provides dual secondary outputs configurable in series or parallel, delivering 56 VCT/28 VCT with current ratings of 80 mA (series) or 160 mA (parallel). With a power rating of 4.4 VA, it utilizes through-hole mounting and Class B insulation.
Feature Summary
- Dual primary winding configuration allows flexible connection to 115 VAC or 230 VAC power sources.
- Secondary windings support both series and parallel configurations for voltage and current flexibility.
- Wide operating frequency range accommodates applications from standard 50/60 Hz up to 500 Hz.
- Through-hole mounting design ensures secure printed circuit board integration.
Applications
- Industrial control systems requiring isolated low-voltage AC power
- Electronic equipment utilizing rectifier circuits for DC conversion
- Instrumentation and measurement devices needing stable signal isolation
Procurement Notes
Verify the specific pinout and terminal configuration against the manufacturer's datasheet before integration. Confirm that the required operating frequency falls within the 50 Hz to 500 Hz range. Ensure the PCB layout supports the through-hole mounting style and physical dimensions. Check insulation class requirements against environmental conditions.
Selection Notes
Select this component when dual voltage input compatibility and variable secondary output configurations are necessary. The wide frequency tolerance makes it suitable for specialized industrial environments. Consider the 4.4 VA power limit and thermal management needs for the specific enclosure. Verify that the through-hole footprint matches the existing board design constraints.
Part Context
This transformer belongs to the Signal Transformer power transformer portfolio, designed for general-purpose industrial and commercial applications. It serves as an isolation component in power supply chains, converting mains or line voltages to lower levels for sensitive electronics. The product emphasizes reliability through Class B insulation standards.
Replacement Considerations
Direct substitutes must match the 4.4 VA rating, 115/230 VAC primary inputs, and 56V/28V secondary outputs. Verify identical mounting styles and electrical isolation characteristics. Cross-reference datasheets for equivalent frequency ranges and current capacities to ensure functional parity.
