Overview
The Hammond Manufacturing 167L70 is a low-voltage industrial power transformer with a 140 VA rating. It features a single primary winding rated for 115 VAC and a center-tapped secondary output of 70 VAC at 2 A. Designed for chassis mounting, the unit measures 3.75 inches in length, 4.5 inches in width, and 4.56 inches in height. It operates at 50 Hz or 60 Hz frequencies within a temperature range of 0°C to +130°C.
Feature Summary
- Enclosed chassis mount design for secure installation
- Center-tapped secondary winding configuration
- Low voltage filament and rectifier compatibility
Applications
- Industrial control panels
- Filament power supply circuits
- Low voltage rectifier applications
Procurement Notes
Verify that the specific order matches the 167L70 model number to ensure correct 140 VA capacity and 70VCT secondary output. Confirm chassis mounting requirements align with available space dimensions. Check for RoHS compliance documentation if required by project specifications. Ensure input voltage matches 115 VAC ratings before integration.
Selection Notes
Select this component when a 140 VA isolation transformer is required for chassis-mounted industrial applications. The 70VCT secondary output suits filament and low voltage rectifier loads. Verify physical dimensions fit the enclosure constraints. Consider thermal management capabilities up to +130°C for high-temperature environments.
Part Context
This part belongs to the Hammond 167 series of industrial power transformers. These units are designed for enclosed chassis mounting and provide reliable low voltage power conversion. The series offers various VA ratings and voltage configurations to meet diverse industrial automation and control panel requirements.
Replacement Considerations
Cross-reference with other Hammond 167 series models such as 167N70 or 167P18 for different VA ratings. Ensure substitute parts maintain identical chassis mounting dimensions and wire lead termination styles. Verify secondary voltage and current ratings match application requirements.
