Phoenix PS-EE Series Single-Phase AC-DC Power Supplies Complete Selection Guide

I. Series Overview: Industrial-Grade Reliable Power Supply for Automation Systems

The Phoenix PS-EE series is a core product line of the ESSENTIAL POWER portfolio, specialized in single-phase AC-DC power conversion for industrial control systems, automation equipment and cabinet-mounted electrical devices. Positioned as a cost-effective industrial standard power supply, it bridges the gap between entry-level STEP series and high-end QUINT/TRIO series, offering a balanced combination of performance, reliability and affordability. This series covers four power ratings (75W/120W/240W/480W) with a unified 24V DC output, featuring global universal AC input (100-240V AC), high conversion efficiency, comprehensive protection mechanisms and standard DIN rail mounting. All variants adopt fanless natural cooling and IP20 protection grade, ensuring stable operation in harsh industrial environments (-20°C to +70°C) and making them ideal power solutions for general industrial control, machinery manufacturing, process automation and small-scale OEM equipment.

III. Nomenclature Decoding: PS-EE Series Model Structure & Full Definition

Universal Model Format

PS-EE-2G/1AC/24DC/[Power]/SC

Key Component & Suffix Interpretation (Critical for Selection)

• PS-EE: Series identifier (Phoenix ESSENTIAL POWER single-phase AC-DC power supply)
• 2G: Functional design code, indicating dual input/output connection terminals for flexible wiring
• 1AC: Input type, single-phase alternating current (100-240V AC universal input)
• 24DC: Output type, 24V direct current (standard industrial control voltage, adjustable 24-28V DC)
• [Power]: Rated output power, including 75W/120W/240W/480W options
• SC: Connection type, screw connection (Screw Connection), ensuring reliable contact for industrial wiring

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

Follow the power demand confirmation → environment & installation matching → connection & certification verification logic to quickly lock the correct model, avoiding complex parameter comparison and fully adapting to industrial power supply requirements.

Step 1: Confirm Power Requirements

1. Calculate the total power consumption of all load devices (sum of rated power of PLC, sensors, actuators, etc.)
2. Reserve 20-30% power margin to cope with load fluctuations, startup inrush current and future system expansion
3. Select the model with rated power closest to and greater than the calculated total power (including margin). Example: Total load 60W → select 75W (1234301); total load 180W → select 240W (1234304)

Step 2: Match Installation Environment & Space

• Environment Temperature: Standard operating temperature -20°C to +70°C; derating is required when ambient temperature >45°C (reduce power by 1% for every 1°C rise above 45°C)
• Installation Space: Confirm cabinet internal width: 75W (33mm) / 120W (48mm) for compact cabinets; 240W (60mm) / 480W (82mm) for medium/large control cabinets
• Vibration & Interference: Applicable to general industrial vibration environments (≤5g); for high-interference scenarios (near inverters/motors), add EMC filters for auxiliary protection
