DST-7-56

Overview

The DST-7-56 is a laminated core power transformer from the Split-Tran series, designed for through-hole mounting. It features dual primary windings rated for 115VAC and 230VAC inputs. The secondary configuration provides parallel 28V or series 56V outputs with a maximum power rating of 36VA. Current capacity is specified as 1.3A in parallel mode and 650mA in series mode. This component utilizes a dual cavity platform architecture.

Feature Summary

• Dual cavity platform design for enhanced structural integrity
• Dual primary winding capability supporting multiple input voltages
• Laminated core construction for efficient magnetic flux transfer
• Through-hole mounting style for secure PCB integration

Applications

• Servo power supply systems
• Industrial automation control circuits
• General purpose AC to DC power conversion stages

Procurement Notes

Verify that the specific order matches the manufacturer part number DST-7-56 from Signal Transformer or Bel Signal Transformer. Confirm the package type is through-hole and the core type is laminated. Ensure the voltage ratings align with system requirements before procurement.

Selection Notes

Select this model when a 36VA transformer is required with dual primary flexibility. It suits applications needing 28V or 56V secondary outputs. Consider the physical dimensions and through-hole requirement during layout planning. Verify compatibility with existing thermal management strategies.

Part Context

This component belongs to the Split-Tran series of power transformers. It is manufactured by Signal Transformer, now part of Bel Fuse. The series is characterized by robust construction suitable for industrial environments. The product line offers various voltage configurations within a standardized form factor.

Replacement Considerations

The ST-7-56 is documented as a similar substitute part number. Both components share the 36VA rating and similar electrical characteristics. Verify mechanical fit and pinout compatibility before swapping.
