2MLP-ACF2 Power Supply: Compact 5V Rail for MasterLogic 200
The Honeywell 2MLP-ACF2 delivers a regulated DC 5V / 6A rail from a wide AC 85–264V input. It suits the MASTERLOGIC 200 Series and similar control racks. Engineers get free-voltage input, built-in fuse protection, and a RUN contact output. The unit weighs only 0.4 kg and accepts 0.75–2 mm² cable with standard compressed terminals.

Why This Module Fits Legacy Control Racks
- Free-voltage input covers 110V and 220V sites without jumpers.
- Built-in UL slow-blow fuse protects the input stage.
- RUN contact gives a hardwired status signal to the host system.
- LED indicator speeds up panel-level fault finding.
- Compact 0.4 kg housing saves cabinet space.
- Short 10–12 ms response supports fast logic handshakes.
Oiltech Controls Review: What Engineers Should Know
- Input range of AC 85–264V handles brownouts better than fixed-tap supplies.
- 6.6A overcurrent trip leaves headroom above the 6A rating.
- Overvoltage clamp at 5.5–6.5V protects downstream logic cards.
- 10 ms interruption tolerance covers most short AC dips.
- Compressed terminals accept RAV 1.25-3.5 and RAV 2-3.5 lugs.
- Mechanical life of 20 million cycles suits high-cycle relay logic.
Oiltech Controls’s Insight: Suitable Equipment
- Honeywell MASTERLOGIC 200 Series control racks
- Legacy PLC I/O chassis needing a 5V rail
- Process panels with 110V or 220V single-phase feed
- Industrial cabinets requiring a RUN status contact
- Retrofit projects replacing fixed-voltage supplies
Installation and Wiring Notes
- Mount vertically on a flat panel for airflow.
- Use 0.75–2 mm² wire with RAV 1.25-3.5 or RAV 2-3.5 terminals.
- Keep AC input leads short and away from 5V output runs.
- Confirm LED is ON after power-up before loading the rail.
- Do not attempt to change the internal fuse.
FAQ
Q: Can I use this supply on both 110V and 220V mains?
A: Yes. The input range is AC 85–264V, so no jumper change is needed.
Q: What happens if the load pulls more than 6A?
A: Overcurrent protection trips at 6.6A or more. Check the load before reset.
Q: How do I know the output is healthy?
A: The LED stays ON when output voltage is normal. Use a meter to confirm 5V ±2%.
Q: Is the fuse replaceable in the field?
A: No. The UL slow-blow fuse is built-in and not user-changeable.
Q: What should I check before buying a used 2MLP-ACF2?
A: Ask for test data on output voltage, overcurrent trip, and RUN contact response. Confirm terminal condition and LED operation. Oiltech verifies these points before shipment.
