C450YNN-1C Johnson Controls Power Module

Overview

The Johnson Controls C450YNN-1C is a dedicated power supply module designed for the System 450 modular electronic control platform. It provides a convenient solution for transforming high-voltage supply power into the 24 VAC Class 2 power required by System 450 control and expansion modules. This module eliminates the need for separate external transformers in applications where 24 VAC power is not readily available, allowing for a clean, streamlined installation within a unified modular control assembly.

Features

• Modular Design: Features plug-together connectors that allow it to link directly with other System 450 modules without the need for internal field wiring.
• Flexible Mounting: Housed in a durable Lexan 950 thermoplastic enclosure that supports easy installation onto a standard DIN rail or direct surface mounting.
• Efficient Power Delivery: Steps down line voltage to safely deliver 10 VA secondary power directly to the control loop system.
• Global Usability: Accommodates dual input configurations to fit varied electrical setups and complies with CE, cULus, and FCC standards.

Specifications

• Input Voltage: 110/120 VAC or 220/240 VAC at 50/60 Hz
• Output Voltage: 24 VAC
• Power Rating: 10 VA maximum secondary power
• Operating Temperature: -40°F to 150°F (-40°C to 66°C)
• Operating Humidity Range: 0 to 95% RH, non-condensing
• Enclosure Material: High-impact thermoplastic (Lexan 950, UL 94 V-0 approved), IP20 rated
• Dimensions: 5.0 inches H x 2.4 inches W x 2.4 inches D (12.7 cm x 6.1 cm x 6.1 cm)

Applications

• System 450 Power Supply: Serves as the foundational power source for custom System 450 configurations monitoring temperature, pressure, and humidity conditions simultaneously.
• HVACR Systems: Ideal for commercial heating, cooling, and refrigeration applications requiring scalable multi-stage or analog control.
• Industrial Processes: Used in commercial and industrial process control environments where compact, field-configurable modular control assemblies are deployed without native 24 VAC power.
