MGV PH1013-2840 Industrial Power Supply – High‑current 28 V DC for demanding control systems

The MGV PH1013-2840 is a robust, high-current AC/DC power supply designed for control cabinets that run heavy loads—think motion axes, DC actuators, large valve banks, or multi-channel I/O with long cable runs. From my experience, teams choose this model when they need a stable 28 V DC rail at up to 40 A with enough headroom over 24 V to overcome line losses and inrush events without tripping protection. It seems to be a reliable drop-in choice for replacing legacy MGV units in packaging, printing, and test stands.

Key Features

• 28 V DC, 40 A output – High-current single output, typically suitable for servo brakes, large solenoids, and multi-axis control loads.
• Wide-range AC input – Universal 100–240 VAC, 50/60 Hz input for global panels without rewiring.
• Tight voltage regulation – Stable output under dynamic loads; you might notice fewer nuisance trips on fast cycling actuators.
• Protection built-in – Over‑voltage, over‑current/short‑circuit, and thermal protection to safeguard both the supply and downstream equipment.
• Clean power – Low ripple and noise for PLCs, sensors, and motion controllers that dislike a “dirty” DC bus.
• Industrial terminals – Rugged screw-type connections for secure wiring inside control cabinets.
• Status indication – Front “DC OK” LED helps maintenance spot issues quickly.

Technical Specifications

Related or Supporting Products

• PULS QT40.241 – 24 V / 40 A DIN-rail supply; a common alternative when the application does not require 28 V headroom.
• Siemens SITOP PSU8200 (40 A variants) – Solid option for Siemens-centric panels; strong ecosystem and diagnostics.
• Phoenix Contact QUINT 40 A – Advanced monitoring and selective fuse breaking add-ons; good for predictive maintenance setups.
• DC distribution and protection – Use appropriately rated DC breakers/fuses and distribution blocks when splitting the 40 A rail across multiple loads.

One thing I appreciate is how the 28 V setting can rescue lines with voltage drop over long cable runs; maintenance leads have mentioned fewer PLC undervoltage alarms after swapping to this unit. A packaging customer noted it tolerated short load peaks from pneumatic valve banks without drama.

Installation & Maintenance

• Cabinet environment – Mount on a rigid panel inside a ventilated enclosure. Keep intake/exhaust areas clear; allow vertical airflow. In many cases, placing it away from heat sources (drives, soft starters) improves life.
• Wiring – Use appropriately sized conductors for 40 A (often 6–10 mm² / AWG 8–6 depending on run length). Tighten screw terminals to the recommended torque to avoid hotspots.
• Protection & grounding – Provide upstream AC protection and proper PE bonding. On the DC side, fuse branch circuits separately to isolate faults.
• Thermal considerations – If the cabinet runs warm, consider forced ventilation. The unit’s efficiency is high, but 1 kW-class supplies still dissipate noticeable heat at full load.
• Routine checks – Periodically remove dust, verify terminal torque, and confirm output voltage (especially if set above 24 V). No firmware updates are typically required.

Quality & Certifications

• CE and RoHS compliant; typical industrial safety approvals (UL/EN for power supplies) apply.
• Manufactured under ISO 9001 quality systems in most cases for this class of product.
• Backed by our 365‑day warranty and expedited logistics options.
