VTX-146-050-118

Overview

The VTX-146-050-118 is a 50VA AC/DC PCB mount power supply from the Vigortronix VTX-146 series. It features a dual secondary output providing two independent 18VAC rails, each rated at 2.78A. The unit accepts a wide input voltage range of 90V AC to 265V AC and delivers a typical efficiency exceeding 70%. Designed for industrial applications, it incorporates comprehensive safety protections including overpower (hiccup mode), overvoltage, and short circuit safeguards. The transformer offers low ripple and noise with fully isolated outputs.

Feature Summary

• Dual secondary windings provide independent 18VAC outputs for complex power requirements
• Integrated safety mechanisms include hiccup mode overpower protection and short circuit defense
• High isolation standards ensure electrical separation between primary and secondary circuits

Applications

• Industrial control systems requiring multiple isolated voltage rails
• Automated machinery and robotics power distribution
• Telecommunications infrastructure equipment
• Medical device power supplies

Procurement Notes

Verify the specific part number against official Vigortronix documentation to confirm pinout compatibility and mounting hole dimensions. Ensure that the required 18VAC dual output configuration aligns with your system design before ordering. Check for any recent updates to the datasheet regarding environmental compliance or RoHS status. Confirm lead times with authorized distributors as manufacturing schedules may vary.

Selection Notes

Select this component when a single PCB-mounted solution is needed for dual 18VAC outputs in industrial environments. Consider the 50VA power rating to ensure adequate capacity for connected loads. Evaluate the physical footprint constraints against the specified dimensions. Verify that the input voltage range matches the available AC source. Assess thermal management needs based on the expected load conditions and ambient temperature.
