Magnetek MG2-1F-3FE

Product Name: Magnetek Impulse·G+ / G2 Series Industrial 24 VDC Output AC-DC Switching Power Supply Module (MG2-1F-3FE)

Product Description: A modular, enclosed single-output switch-mode power supply unit (PSU) from Magnetek’s MG2/G2 family, designed to provide regulated 24 VDC for cranes, hoists, industrial automation cabinets, and magnet/brake supplies. Some references also classify the MG2-1F-3FE as a compact AC drive in certain crane-control contexts, but the predominant industrial listing identifies it as a 24 VDC industrial SMPS with N+1 redundancy capability.

Category: Others

Description

Technical Specifications (Industrial SMPS Interpretation — most common):

Model: MG2-1F-3FE
Input Voltage: 100–240 VAC, 50/60 Hz (auto-ranging), single-phase
Input Current: ~3–6 A @ 115 VAC / ~2–3 A @ 230 VAC (depends on load)
Output Voltage: 24 VDC adjustable (±10 % trim)
Rated Output Current: 13 A – 25 A (typical 20 A / 480 W–600 W depending on sub-version)
Output Power: 300 W – 600 W
Efficiency: 85 % – 90 %
Ripple & Noise: < 1 % pk-pk
Protections: Over-voltage, over-current, short-circuit, over-temperature (auto-recovery)
Cooling: Natural convection or fan-assisted (model dependent)
Indicators: Green LED — DC OK
Mounting: DIN rail (35 mm) or panel mount via brackets
Operating Temp: -10 °C to +70 °C (derate above 50 °C)
Compliance: UL 508, CSA, CE, EN 60950/ EN 50178

(If encountered as a crane-duty AC inverter in a Magnetek Impulse series context, it would be a 3-phase 480 V input, 1.5–2 HP VFD — confirm by physical label.)

Features:

Parallel operation for N+1 redundancy
Wide AC input range — suitable for global deployment
Short-circuit proof with auto-restart after fault clears
DC OK contact for remote alarm to PLC

Applications: 24 VDC power for PLCs, sensors, Magnetek brake magnets, hoist controls, conveyor control panels, communication equipment.

Construction & Materials: Metal vented enclosure (painted steel or aluminum), terminal block for AC in / DC out / DC OK contact, trim potentiometer under cover.

Working Principle: AC mains → EMI filter → full-wave rectifier → high-frequency transformer via PWM controller → secondary rectifier & LC filter → regulated 24 VDC output; feedback optocoupler maintains voltage regulation under load variation.

Installation & Precautions:

Verify input voltage selector (if present) matches local mains BEFORE energizing.
Leave adequate clearance above/below for convection cooling (follow derating curve).
Tighten DC output terminals to spec — loose connections cause voltage drop / heating.
Fuse AC input per manufacturer recommendation.
For parallel (redundant) operation, use OR-ing diodes or built-in paralleling feature — consult manual.
Do NOT exceed rated ambient temperature; if installed in enclosed cabinet monitor internal temp.
