Features & Benefits

1. Global Voltage Compatibility: 85–264 VAC input range eliminates the need for separate 110 V and 220 V power supply variants, simplifying global inventory and spare parts management.
2. High Current Output: 6 A at 5 VDC supports fully loaded MasterLogic-200 chassis with multiple high-density I/O and communication modules.
3. Built-In Protection Suite: Overcurrent (≥ 6.6 A), overvoltage (5.5–6.5 V), and slow-blow fuse protection safeguard the power supply and downstream modules.
4. RUN Relay Output: Form-C contact with 24 VDC @ 0.5 A rating enables external power-status monitoring and safety interlocking.
5. Visual Diagnostics: Front-panel LED provides immediate confirmation of normal output voltage, reducing troubleshooting time.
6. Compact Footprint: 55 × 95 × 90 mm dimensions and 0.38 kg weight allow high-density mounting in space-constrained control panels.

FAQ

Q: What is the difference between 2MLP-ACF2 and 2MLP-ACF1?
A: The 2MLP-ACF2 delivers DC 5 V at 6 A. The 2MLP-ACF1 delivers DC 5 V at 3 A plus an auxiliary DC 24 V at 0.6 A output. Choose ACF2 for higher 5 V current capacity; choose ACF1 if your application requires an auxiliary 24 V supply.

Q: Can this module operate on both 110 VAC and 220 VAC?
A: Yes, the 85–264 VAC input range allows direct connection to 110 VAC, 220 VAC, or 240 VAC industrial power without manual voltage selection.

Q: Is the input fuse replaceable?
A: No, the module contains a built-in UL-standard slow-blow fuse that is not user-replaceable. If the fuse blows, replace the entire module.

Q: What does the RUN relay output indicate?
A: The RUN relay closes when the output voltage is within specification, providing a 24 VDC @ 0.5 A signal suitable for status lamps, PLC inputs, or safety interlock circuits.

Installation Guide

• Install the module into the power supply slot of a MasterLogic-200 main or expansion base.
• Connect AC power (L, N, PE) to the input terminals using 0.75–2 mm² wire with RAV1.25-3.5 or RAV2-3.5 crimp terminals.
• Connect the ground (PE) terminal to the cabinet earth bus for safety and electromagnetic compatibility.
• Wire the RUN relay output to your status monitoring circuit if remote power supervision is required.
• Verify the front-panel LED illuminates to confirm normal output voltage before energizing I/O modules.
• Ensure the control cabinet provides adequate ventilation to maintain the module within its 0°C to +55°C operating range.

Selection Tips

• Current Capacity: The 2MLP-ACF2 provides 6 A at 5 VDC. Calculate the total current draw of your CPU, I/O, and communication modules to ensure the 6 A limit is not exceeded. For lighter loads, the 2MLP-ACF1 (3 A) offers a cost-optimized alternative.
• Voltage Environment: The 85–264 VAC range covers most global industrial voltages. If your plant uses DC input exclusively, consider the 2MLP-DC42-CC (DC 24 V input) instead.
• Redundancy: The 2MLP-ACF2 is a single power supply module. For redundant power architectures, use the 2MLR-AC12 (110 VAC) or 2MLR-AC22 (220 VAC) redundant power modules designed for MasterLogic-200R systems.
• Cabinet Ventilation: At full 6 A load, ensure the control cabinet has sufficient airflow or cooling fans to prevent thermal derating.
