Power Conversion and Protection Architecture

• AC Input Stage: Accepts 85–132 VAC input across 47–63 Hz.
• DC Output Stage: Provides regulated 5 VDC power with ±2% voltage tolerance.
• Output Capacity: Delivers 8.5 A and 46.75 W at 55°C.
• Overcurrent Protection: Provides protection within the specified 9.3–17.0 A range.
• Input Fuse: Uses an integrated, non-user-replaceable fuse.
• RUN Contact: Supports external monitoring of the module's operating status.
• Voltage Indicator: Displays normal output voltage through the front-panel LED.

Integrated Fuse Ratings:

• AC input: 250 V / 3.15 A, UL-approved time-lag type.
• DC input: 125 V / 10 A, UL-approved time-lag type.
• Both fuses are built into the module and are not user-replaceable.

Installation Guidelines

1. Verify the Model: Confirm the module designation as 2MLR-AC13 before installation.
2. Check Input Power: Verify 110 VAC nominal input and the permitted 85–132 VAC range.
3. Inspect Wiring: Use cables within the specified 0.75–2 mm range.
4. Select Terminals: Use compatible RAV1.25-3.5 or RAV2-3.5 crimp terminals.
5. Check Connections: Verify input polarity requirements and terminal assignments against the manufacturer's wiring documentation.
6. Secure Installation: Mount the module in its designated system position.
7. Inspect Clearance: Maintain sufficient space for ventilation and electrical maintenance.
8. Apply Power: Energize the module after completing wiring and safety inspections.

Important: Disconnect the power source before installation or wiring changes. Follow the original equipment manufacturer's grounding and electrical safety requirements.

Commissioning and Maintenance

Check the module's input and output conditions during initial commissioning. Use the following inspection points:

• Input Voltage: Confirm the supply remains within 85–132 VAC.
• Output Voltage: Verify the 5 VDC output within its ±2% tolerance.
• Output Loading: Keep the operating current within the 8.5 A rating.
• LED Status: Confirm the voltage indicator illuminates under normal conditions.
• RUN Contact: Check contact switching through the connected monitoring circuit.
• Terminal Condition: Inspect wiring tightness and signs of overheating.
• Ventilation: Keep surrounding airflow paths free from obstructions.

The integrated fuse is not user-replaceable. Replace the complete module if internal fuse failure occurs.

System Compatibility Notes

• The 2MLR-AC13 belongs to the Honeywell MasterLogic product family.
• Its 5 VDC output supports compatible system power requirements.
• Verify the rack, base, and controller power specifications before installation.
• Check the system's total power consumption against the module's output capacity.
• Confirm terminal assignments and mechanical mounting compatibility with the original system documentation.
• Do not assume compatibility with other MasterLogic power supply models based on appearance alone.

Engineering Note: The supplied specifications do not identify a complete list of compatible controller models or rack configurations. Confirm the exact hardware combination before replacement or system expansion.

Frequently Asked Questions

Q1: What is the main function of the Honeywell 2MLR-AC13?

The module converts AC input power into regulated 5 VDC power. It supplies compatible MasterLogic system components with up to 8.5 A.

Q2: Can the 2MLR-AC13 operate with a 120 VAC power source?

Yes. Its specified input range covers 85–132 VAC. A 120 VAC source falls within this range.

Q3: What should engineers check when the output voltage LED does not illuminate?

First, measure the AC input voltage and inspect the input wiring. Then check the connected load and output terminals. An internal fuse or power circuit fault may require module replacement.

Q4: How should engineers evaluate the 8.5 A output capacity?

Calculate the combined current demand of all connected loads. Keep the total within 8.5 A. Also consider the specified 46.75 W output rating at 55°C.

Q5: What information should buyers confirm before ordering a replacement?

Confirm the complete 2MLR-AC13 model number, input voltage, output rating, mounting arrangement, and terminal configuration. Compare the existing module's specifications with the replacement requirements. This reduces commissioning delays and avoids power supply mismatches.
