Overview
The Signal Transformer DP-241-5-120 is a laminated core power transformer designed for chassis mounting. It features dual primary windings rated for 115 VAC and 230 VAC input, providing a single secondary output of 120 VCT at 100 mA. The unit has a power rating of 12 VA and operates at frequencies of 50 Hz or 60 Hz. Electrical isolation is specified at 2500 Vrms. Physical dimensions are 71.4 mm in length, 36.3 mm in width, and 42.8 mm in height. Termination is achieved via quick connects and solder lugs.
Feature Summary
- Dual primary winding configuration supports flexible voltage selection between 115 VAC and 230 VAC inputs.
- Chassis mount design facilitates secure installation within industrial control enclosures.
- Split bobbin construction provides enhanced electrical isolation between windings.
Applications
- Industrial control panel power supply circuits
- Servo drive system power distribution
- Equipment requiring isolated 120 VAC control signals
Procurement Notes
Verify the specific termination style required for your application, as this model utilizes both quick connect terminals and solder lugs. Confirm that the chassis mounting holes align with your enclosure specifications. Ensure the operating environment remains within the specified temperature range to maintain performance reliability. Check for any recent production changes or packaging updates before finalizing orders.
Selection Notes
Select this component when a compact, high-isolation transformer is needed for dual-voltage primary applications. The 12 VA rating suits low-power control circuits rather than heavy loads. Consider the physical footprint constraints against the 71.4 mm length dimension. Verify that the 2500 Vrms isolation meets safety standards for your specific equipment class.
Part Context
This part belongs to the Two-4-One series from Signal Transformer, known for split bobbin designs. It serves as an alternative to other models in the 241 family, such as the 241-5-120, though termination styles may differ. The series is widely used in industrial automation where space efficiency and reliable isolation are critical requirements.
Replacement Considerations
Public confirmed substitute part numbers include 186D120 from Hammond Manufacturing and F5-120 from Triad Magnetics. Verify mechanical mounting compatibility and electrical pinout alignment before substituting.
