RP135-30-1-S

Overview

The Astrodyne TDI RP135-30-1-S is a single-output, regulated DC power supply designed for industrial and commercial applications. It delivers a nominal output voltage of 30V with a maximum current capacity of 4.5A, resulting in a total power rating of 135W. The unit features universal AC input compatibility, accepting line voltages from 85 to 264VAC across a frequency range of 47 to 440Hz. It incorporates comprehensive protection mechanisms including short-circuit, overload, and over-temperature safeguards. The device operates within an ambient temperature range of -10°C to +70°C and includes remote sense capabilities to compensate for voltage drop in load leads.

Feature Summary

• Universal wide-range AC input capability supporting global voltage standards
• Integrated remote sensing terminals for precise load regulation
• Built-in multi-protection circuitry ensuring operational safety under fault conditions

Applications

• Industrial automation control systems
• Telecommunications infrastructure equipment
• Medical diagnostic devices requiring stable DC power

Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure correct pinout and connector type. Confirm that the required input voltage range matches your local electrical infrastructure. Ensure adequate ventilation space is allocated around the unit to maintain thermal performance within specified limits during continuous operation.

Selection Notes

Select this model when a fixed 30V output is required with up to 4.5A current demand. Consider the physical dimensions and mounting style if panel integration is necessary. Evaluate the need for remote sensing based on cable length between the power supply and the load to determine if voltage compensation is critical for system accuracy.

Part Context

This unit belongs to the RP135 series of open-frame or enclosed DC power supplies from Astrodyne TDI. The series is engineered for reliability in demanding environments. The RP135-30-1-S specifically denotes the 30V output variant within this power class, sharing common internal topology and protection features with other models in the family while differing in output specifications.

Replacement Considerations

Direct replacements must match the 135W power rating, 30V output, and 4.5A current capacity. Verify mechanical footprint compatibility for existing enclosures. Check that replacement units support the same input voltage range and offer equivalent protection features such as short-circuit and over-temperature shutdown.
