CV120600 Isolation Transformer 120V to 120V 600VA Equivalent & Substitute Parts

Part Overview

The CV120600 is an isolation transformer manufactured by Hammond Manufacturing, designed to provide galvanic isolation between primary and secondary circuits at 120V AC with a maximum power rating of 600VA. This transformer features NEMA 5-15P input and NEMA 5-15R output connectors, making it suitable for standard North American electrical applications requiring isolation.

The CV120600 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for replacement or upgrade scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CV120600 is determined by the following critical parameters:

• Transformer Type: Isolation transformer (galvanic isolation required)
• Voltage Configuration: 120V primary to 120V secondary (1:1 turns ratio)
• Power Rating: Minimum 600VA to maintain load capacity
• Input Connector: NEMA 5-15P (standard North American plug)
• Output Connector: NEMA 5-15R configuration for load connection
• Regulatory Compliance: ROHS3 and REACH compliance maintained

The substitute part 178ET meets these criteria with equivalent electrical specifications and enhanced availability as an active product.

Parameter Comparison

Engineering Selection Recommendations

The 178ET serves as a direct substitute for the CV120600 based on the following factors:

Electrical Compatibility: Both transformers provide identical primary and secondary voltage specifications (120V to 120V) with isolation transformer topology. The 178ET offers increased power capacity at 750VA, exceeding the CV120600's 600VA rating, ensuring adequate headroom for existing loads.

Connector Compatibility: Both parts utilize NEMA 5-15P input connectors. The output configuration differs (4 outlets on CV120600 versus 2 outlets on 178ET); this difference requires evaluation based on the specific application's outlet requirements.

Product Status and Compliance: The 178ET is an active product with current manufacturing support, whereas the CV120600 is obsolete. Both maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Physical Considerations: The 178ET weighs 26 lbs (11.8 kg) compared to the CV120600's 53 lbs (24 kg), representing a significant reduction in mass and installation footprint.

Frequently Asked Questions (FAQ)

Q: Can the 178ET directly replace the CV120600 in all applications?

A: The 178ET provides equivalent electrical isolation and voltage transformation. The primary consideration is the output connector configuration: the CV120600 provides 4 NEMA 5-15R outlets while the 178ET provides 2 outlets. Verify that your application's outlet requirements align with the 178ET's configuration.

Q: What is the significance of the higher 750VA rating on the 178ET?

A: The 178ET's 750VA rating exceeds the CV120600's 600VA specification. This provides additional capacity margin and does not create compatibility issues; the transformer will operate safely with loads up to 600VA.

Q: Are there any regulatory or compliance differences between these parts?

A: Both the CV120600 and 178ET maintain identical ROHS3 compliance and REACH unaffected status. No regulatory barriers exist for substitution.

Q: Why is the CV120600 listed as obsolete?

A: Obsolescence indicates that the manufacturer has discontinued production. The 178ET, as an active product, represents the current manufacturing alternative from Hammond Manufacturing for this transformer category.

Q: Does the weight difference affect installation?

A: The 178ET's reduced weight (26 lbs versus 53 lbs) may simplify mounting and installation procedures. Verify that your installation structure accommodates the lighter mass without requiring design modifications.
