III. Nomenclature Decoding: ESSENTIAL-PS Model Structure & Definition

Universal Model Format

ESSENTIAL-PS/[AC Input Phase]/[DC Output Spec]/[Power Rating]/[Grade Suffix]

Full Component Interpretation (One-Click Understanding)

• ESSENTIAL-PS: Phoenix industrial essential switching power supply series identifier (standard industrial grade)
• AC Input Phase: 1AC = Single-phase AC input (85-264V AC, global universal) | 3AC = Three-phase AC input (320-575V AC, for 3-phase industrial mains)
• DC Output Spec: 24DC = Fixed 24V DC output (the most common industrial control voltage)
• Power Rating: 120W/240W/480W/960W = Rated output power, matching the maximum load capacity of the power supply✔ 120W → 5A output | 240W →10A output | 480W→20A output |960W→40A output
• EE: Standard industrial-grade suffix (full protection functions, standard efficiency, DIN rail mount, the universal grade for this series)

IV. 3-Step Quick Selection Technique (100% Accurate Matching)

Follow the AC input phase → power demand → installation verification logic to quickly lock the correct model, with zero complex parameter comparison, fully adapting to industrial power supply selection requirements.

Step 1: Confirm the AC Input Phase (Core Precondition)

✅ Single-phase mains supply (factory/office 1-phase power) → Select 1AC series (2910586/2910587/2910588) – applicable to most general industrial scenarios✅ Three-phase mains supply (3-phase industrial power grid) → Select 3AC series (1018291/1018299/1018294) – only for 3-phase industrial sites/machinery

Step 2: Match the Power Rating by Load Demand (Key Selection)

Calculate the total power of the connected devices and select the power supply with a 1.2x rated power margin (industrial design standard)✅ Light load (≤5A, small sensors/modules) → 120W (2910586)✅ Standard load (5-10A, general I/O/controller) →240W (1018291/2910587)✅ Medium load (10-20A, multi-module automation) →480W (1018299/2910588)✅ Heavy load (20-40A, large-scale systems/heavy machinery) →960W (1018294)

Step 3: Final Verification of Industrial Adaptability

✅ All models support DIN rail (NS35/7.5) mounting, directly applicable to standard control cabinets✅ All models have full protection functions (OV/OC/OT/SC), no additional protection module required✅ All models are compatible with 24V DC industrial control systems, matching Phoenix and third-party 24V devices

V. Selection Pitfall Avoidance Guide (Critical for Power System Stability)

Avoid the 4 most common selection errors of the ESSENTIAL-PS series to ensure the safety, stability and service life of the power supply and connected equipment.

1. Input Phase Mismatch: Using 3AC power supply for 1-phase mains or vice versa → Strictly distinguish 1AC/3AC models according to the on-site power grid type, otherwise the power supply will fail to work.
2. Power Underconfiguration: Selecting a power supply with rated power equal to the total load power → Reserve a 20% power margin (e.g., 20A load select 960W/40A), avoid overload and overheating.
3. Voltage Misunderstanding: Confusing 24VDC output with other DC voltages → All models are fixed 24VDC output, only applicable to 24V industrial control systems.
4. Environmental Neglect: Using the power supply in environments exceeding -25°C/+70°C → The series only supports -25°C~+70°C; for extreme temperature, additional cabinet heating/cooling equipment is required.

VI. Conclusion: Reliable 24V DC Power for Industrial Automation

The Phoenix ESSENTIAL-PS series provides a one-stop 24V DC industrial power supply solution covering 1AC/3AC input and 120W-960W power grades, with industrial-grade stability, comprehensive protection and compact design. These power supplies are the core power components for industrial control cabinets, automation systems and industrial machinery, ensuring stable and uninterrupted power supply for field devices, controllers and I/O modules in harsh industrial environments.
