SLT-300

Power Transformers Overview

The SLT-300 is a laminated core power transformer with a 300VA rating. It features a 277V primary and 120V secondary winding, delivering a maximum output current of 2.5A. Designed for chassis mounting, it utilizes terminal block termination. The unit meets Class F insulation system requirements (+155°C) and holds UL, CSA, VDE, and IEC approvals. Electrical isolation is rated at 4000Vrms.

Power Transformers Feature Summary

• Chassis mount construction with terminal block termination
• Class F insulation system rated for +155°C operation
• Touch-safe terminals meeting IP20 type standards
• Multiple international safety certifications including UL, CSA, VDE, and IEC

Power Transformers Applications

• Industrial control panels requiring step-down voltage conversion
• Equipment needing isolated power supplies with high safety ratings
• Applications requiring chassis-mounted transformers with terminal block connections

Power Transformers Procurement Notes

Verify the specific datasheet version (SLT-300(1).pdf through SLT-300(3).pdf) to confirm exact pinout and mechanical dimensions. Ensure the application environment supports the Class F insulation temperature limit of +155°C. Confirm that the 277V primary input matches the source voltage. Check that the chassis mounting style and terminal block termination are compatible with the enclosure design.

Power Transformers Selection Notes

Select this component when a 300VA capacity is required for stepping down 277V to 120V. The chassis mount form factor is suitable for open-frame installations where direct panel mounting is preferred over PCB integration. The terminal block interface simplifies wiring in industrial settings compared to soldered leads. Verify that the 4000Vrms isolation voltage meets the safety requirements of the target equipment.

Power Transformers Part Context

This part belongs to the Signal Transformer power transformer lineup, specifically designed for general-purpose power distribution. It serves as a step-down solution for converting higher primary voltages to standard secondary levels. The laminated core construction provides efficient magnetic coupling for AC power applications.
