Siemens S7-300 PS307 6ES7307-1EA01-0AA0 Power Supply 24V 5A PLC Unit

Description

The Siemens SIMATIC PS307 Regulated Power Supply Unit (6ES7307-1EA01-0AA0 / 6ES7 307-1EA01-0AA0) is a single-phase system and load power supply custom-engineered for the SIMATIC S7-300 PLC platform. It steps down and regulates 120 V AC or 230 V AC mains utility power to a smooth, low-ripple 24 V DC output. Capable of delivering up to 5 A of continuous current, this unit powers central processing units (CPUs), signal modules (SM), functional modules (FM), and connected field sensors or actuators.

Designed with automatic input voltage range selection, the PS307 adapts effortlessly to single-phase AC supply networks. In Bangladesh’s industrial sector—where grid voltage fluctuations can disrupt sensitive automation electronics—this regulated supply acts as a critical line of defense, ensuring uninterrupted PLC operation in automotive, packaging, textile, and general assembly lines.

Key Features

• Regulated 24V DC / 5A Output: Supplies up to 120 W of stable DC power to S7-300 CPU racks and auxiliary control circuits.
• Automatic Range Switchover: Detects and adapts to nominal line input voltages of 120 V AC and 230 V AC without manual jumper reconfiguration.
• Seamless Rack Integration: Shares the identical housing design and DIN rail mounting footprint as SIMATIC S7-300 I/O modules for clean panel assembly.
• Connecting Comb Included: Integrates directly with the adjacent CPU or module to supply operating voltage across the rack.
• Comprehensive Visual Diagnostics: Front-panel green LED indicates normal 24 V DC output voltage status for fast troubleshooting.

Installation & Maintenance Guide

Installation Requirements:

• Always disconnect the main AC supply voltage before installing, wiring, or removing the power unit.
• Hook the PS307 unit onto the standard S7-300 DIN mounting rail to the far left position (Slot 1) and tighten the top securing screw.
• Wire the AC supply lines (L1, N, and PE ground) to the input terminals using appropriately rated cables.
• Insert the supplied power connecting comb into the output terminals to feed 24V DC directly to the adjacent S7-300 CPU.

Maintenance Tips:

• Periodically check that screw terminals are tight and free from oxidation or loose strands.
• Keep control cabinet ventilation louvers and internal cooling fans free from dust to maintain air circulation around the module.
• Check the green front LED (“24V OK”) during routine panel inspections to confirm proper output voltage delivery.

Safety Instructions:

• Ensure protective earth (PE) is properly grounded to guard against static buildup and high-voltage surges.
• Do not exceed the maximum output current rating of 5A; add additional load power supplies if field sensor demand increases.
• Installation must be performed by certified electrical engineers or qualified automation technicians.
