Overview
The Signal Transformer ECO-170-28 is a laminated core power transformer rated at 170VA. It features dual primary windings for 115V and 230V operation in parallel, and dual secondary windings providing 14V or 28V configurations. The unit supports maximum currents of 12A in parallel mode and 6A in series mode. It utilizes screw terminal connections for chassis mounting and offers a dielectric strength of 4000Vrms.
Feature Summary
- Dual primary winding configuration supporting both 115V and 230V input voltages
- High dielectric isolation strength of 4000Vrms between windings
- Laminated core construction designed for industrial power applications
Applications
- Industrial power supply units requiring high isolation
- Chassis-mounted equipment needing robust voltage transformation
- Drive isolation systems in heavy machinery
Procurement Notes
Verify the specific datasheet version to confirm terminal type and mounting dimensions, as distributor listings may vary between screw terminal and pin styles. Ensure the required current rating (12A parallel vs 6A series) matches the circuit design before ordering. Confirm RoHS compliance status with the manufacturer if environmental regulations apply to the final assembly.
Selection Notes
Select this model when a 170VA capacity and 4kV isolation are mandatory. Compare against the DST series for lower power requirements or through-hole mounting needs. Evaluate thermal management capabilities based on the 170VA load. Consider the physical footprint for chassis integration compared to smaller surface mount alternatives.
Part Context
This component belongs to the EcoTran series by Signal Transformer, which provides industrial-grade power transformers ranging from 105VA to 450VA. The series is characterized by split bobbin designs and high dielectric strength, suitable for demanding environments where electrical isolation and reliability are critical for system safety.
Replacement Considerations
Direct substitutes within the same series include ECO-170-230 for different secondary voltage outputs. For lower power needs, the DST-6-28 offers similar electrical characteristics but with significantly reduced VA rating and different mounting styles.
