Honeywell 2MLR-AC13 110VAC Power Supply Module

Honeywell 2MLR-AC13 Power Supply Module

Product Introduction

The Honeywell 2MLR-AC13 is a power supply module designed for AC input applications. It accepts a rated input voltage of 110 VAC with a wide range from 85V to 132VAC. This module converts the AC power to a regulated 5 VDC output at 8.5A. The total output power reaches 46.75W when operating at 55℃ ambient temperature.

Moreover, the 2MLR-AC13 achieves an efficiency of 65% or higher. A built-in, non-user-replaceable fuse protects the module from overcurrent events. The RUN contact provides a dry contact signal that indicates normal output voltage status. An LED on the front panel offers a quick visual confirmation of operation.

Mechanical and Environmental Data

The Honeywell 2MLR-AC13 measures 55 x 95 x 90 mm (W x H x D). This compact footprint saves valuable space inside control panels. The module weighs only 334g, which reduces mechanical stress on DIN rails and mounting brackets.

For reliable wiring, use clamped terminals such as RAV1.25-3.5 or RAV2-3.5. The recommended cable cross-section ranges from 0.75 mm² to 2 mm². This range accommodates most industrial control wiring requirements. The module operates reliably at ambient temperatures up to 55℃ while delivering full output power.

Frequently Asked Questions (FAQ)

1. Can I use the Honeywell 2MLR-AC13 with 220VAC power?

No, this module is designed exclusively for 110VAC input (85-132VAC range). For 220VAC applications, please select a different Honeywell power supply model with dual or wide-range input capability.

2. What happens if the output current exceeds 8.5A?

The overcurrent protection circuit activates between 9.3A and 17.0A. It will shut down the output to prevent damage to the module and connected devices. After removing the overload condition, power cycle the module to restore normal operation.

3. How do I know if the RUN contact is working properly?

Apply 24VDC to one terminal of the RUN contact. Connect the other terminal to a PLC input or a small relay. When the 2MLR-AC13 output is normal, the contact closes. You should measure continuity across the contact terminals. The response time from power-on to contact closure is 10ms or less.

4. The LED is off even though AC power is present. What should I check?

First, verify that the AC input voltage measures between 85V and 132VAC at the module terminals. Next, check the external circuit breaker or fuse upstream. If both are good, the internal fuse may have blown due to a severe overvoltage or internal fault. In this case, the module requires replacement since the fuse is not user-replaceable.

5. What cable size is recommended for the AC input wiring?

Use copper wire with a cross-section between 0.75 mm² and 2 mm². We recommend using clamped terminals such as RAV1.25-3.5 or RAV2-3.5 for a secure and vibration-resistant connection. For 110VAC input, ensure the wire insulation rating is at least 300V.
