Honeywell 2MLR-AC13 Power Supply Module Overview

The Honeywell 2MLR-AC13 converts 110VAC input to stable 5VDC output. It belongs to the Honeywell 2MLR power supply family. This module accepts an input voltage range of 85V to 132VAC. The input frequency covers 50/60 Hz from 47 to 63 Hz. Engineers use it to power logic circuits and I/O modules in control racks.

Technical Specifications

The Honeywell 2MLR-AC13 has a maximum input power of 176 VA or 72W. Its efficiency reaches 65% or higher under normal operation. The inrush current peaks at 20A and stays within 8 milliseconds. This low inrush reduces stress on upstream circuit breakers.

The input fuse is built-in and non-replaceable by users. The AC power fuse is rated at 250V / 3.15A time-lag type. The DC power fuse is rated at 125V / 10A time-lag type. Both fuses carry UL approval for safety compliance. The allowed instantaneous interruption lasts within 20 milliseconds.

The output voltage is 5VDC with a tolerance of ±2%. The output current delivers 8.5A continuously. Output power reaches 46.75W at 55°C ambient temperature. Overcurrent protection activates between 9.3A and 17.0A. This protection prevents damage to connected loads.

RUN Contact Specifications

The Honeywell 2MLR-AC13 includes a dedicated RUN contact. This contact serves status monitoring purposes. The rated switching voltage and current are 24VDC at 0.5A. The minimum switching load is 5VDC at 1 milliampere. Response time for Off→On is 10 milliseconds or lower. Response time for On→Off is 12 milliseconds or lower.

Mechanical life exceeds 20 million operations. Electrical life reaches 100,000 operations at rated switching current. The voltage status display uses an LED indicator. This LED turns on when the output voltage is normal.

Physical Dimensions and Wiring

The Honeywell 2MLR-AC13 measures 55mm in width, 95mm in height, and 90mm in depth. Its unit weight is 334 grams for the bare module. The packaged weight reaches 0.55 kg including protective materials.

The recommended cable size ranges from 0.75 to 2 mm². Available clamped terminals include RAV1.25-3.5 and RAV2-3.5 types. Use copper wires only with the terminal connections. Tighten all screws to the specified torque values.

Installation Guidance

Mount the Honeywell 2MLR-AC13 in a suitable control cabinet. Ensure proper ventilation around the module. Connect AC input wires to the correct terminals. Observe polarity for DC output connections. Do not attempt to replace the internal fuses. The fuses are non-replaceable by users. Verify the LED indicator lights up after power application.

Frequently Asked Questions (FAQ)

1. Can the Honeywell 2MLR-AC13 work on 220VAC input?
No, this module accepts only 85V to 132VAC input range. Use a step-down transformer if needed.

2. What does the RUN contact do on this power supply?
The RUN contact signals that the output voltage is normal. It switches 24VDC at 0.5A maximum.

3. Can I replace the input fuse myself?
No, both AC and DC fuses are built-in and non-replaceable. Return the module for service if the fuse fails.

4. What is the maximum output power at high temperature?
The Honeywell 2MLR-AC13 delivers 46.75W at 55°C ambient temperature.

5. How do I know if the module is working properly?
Check the voltage status LED on the front panel. The LED turns on when output voltage is normal.
