1182Q12

Overview

The Hammond Manufacturing 1182Q12 is a toroidal power transformer rated at 160 VA. It features dual primary windings supporting 115 VAC and 230 VAC inputs, and dual secondary windings providing a 12 V output at 13.34 A in parallel configuration or 24 V in series. The unit utilizes wire lead termination for chassis mounting. Key electrical specifications include a 4000 Vrms isolation voltage and operation at 50 Hz/60 Hz frequencies.

Feature Summary

• Toroidal core design for high efficiency and low profile
• Dual primary and secondary winding configurations for flexible voltage input and output
• Chassis mount installation style with wire leads
• High isolation voltage rating

Applications

• Industrial control systems requiring stable low-voltage power
• Electronic equipment needing isolated AC power sources
• Custom power supply assemblies

Procurement Notes

Verify the specific suffix code to confirm the exact secondary voltage and current ratings, as the 1182 series uses alphanumeric codes to denote different tap configurations. Confirm that the required mounting hardware is included, noting that larger capacity models may have different inclusion policies. Ensure the application environment supports the specified operating frequency range of 50 Hz or 60 Hz.

Selection Notes

Select this model when a 160 VA toroidal transformer is required with a 12 V secondary output. The dual primary winding allows compatibility with both 115 VAC and 230 VAC mains supplies. Consider the physical dimensions and weight constraints, as toroidal transformers are generally heavier than equivalent EI-core units but offer superior magnetic shielding and lower noise profiles.

Part Context

This component belongs to the Hammond 1182 series of industrial toroidal power transformers. The series spans from 30 VA to 1500 VA, offering various voltage combinations. The 1182Q12 specifically addresses applications needing higher current delivery at low voltage, utilizing the standard chassis-mount form factor common across the series for easy integration into enclosures.

Replacement Considerations

Direct replacements within the same series include other 1182 models with matching VA ratings but different secondary voltages, such as 1182K117 (117V) or 1182L110 (110V). Cross-manufacturer equivalents must be verified for identical footprint, mounting hole spacing, and electrical isolation ratings.
