Expert Review – Performance & Safety
The 6ES7307-1EA01-0AA0 delivers clean 24 V with low ripple. Its 20 A overload capability handles motor or capacitor inrush. ATEX and FM approvals allow use in hazardous zones. The 87 % efficiency keeps panels cool.
Manager’s Insight – Practical Use
This supply simplifies S7‑300 system design. The fixed 24 V output removes adjustment errors. Its compact 60 mm width saves rail space. With DNV and LRS marine approvals, it fits shipboard automation too.
Best Suited For
- Siemens S7‑300 PLC racks and I/O modules
- Sensor and actuator power in factory automation
- Hazardous area equipment (ATEX / FM certified)
- Marine control panels (DNV, LRS approved)
- General industrial 24 V DC loads up to 5 A
Frequently Asked Questions (FAQ)
- Is the output voltage adjustable?
No, it is fixed at 24 V DC with a ±3 % tolerance. - What happens during a short circuit?
The supply shuts down electronically and restarts automatically when the fault clears. - Can I mount this on a standard DIN rail?
Not directly – you need the optional mounting adapter (6EP1971-1BA00). - Does it have a warranty?
Yes, 12 months covering manufacturing defects. - What shipping options are available?
We dispatch within 12‑24 hours via FedEx, UPS, or DHL.
Experience‑Based Buying Guide
- Verify your input voltage – this unit auto‑selects 120 or 230 V AC.
- Add up all 24 V loads – do not exceed 5 A continuous.
- For short peaks (up to 20 A), ensure the duration stays under 100 ms.
- If mounting on a standard rail, order the adapter separately.
- For explosive environments, confirm ATEX or FM certification matches your zone.
Ordering & Delivery
