Industry Applications
The 6EP1336-3BA10 is ideal for powering PLCs, DCS systems, sensors, and actuators in manufacturing lines, process plants, and machine tools. Its high efficiency reduces electricity bills, while the buffering time of 20 ms at rated load prevents data loss during power dips. For marine applications, it holds approvals from ABS and DNV, making it suitable for offshore and shipboard automation.
Installation Guide
Mount the Siemens 6EP1336-3BA10 onto a standard DIN rail (EN 60715 35x7.5/15). Ensure minimum spacing of 50 mm above and below for airflow. Use screw terminals for input (L, N, PE) and output (+, -) with wire sizes 0.2–4 mm². For remote ON/OFF and alarm signaling, connect to terminals 15/16 and 13/14 respectively. No overshoot on startup (soft start) protects sensitive loads.
Maintenance & Reliability
With an MTBF of over half a million hours, the 6EP1336-3BA10 requires minimal maintenance. Periodic inspection of the green "24V OK" LED and ventilation grilles is recommended. The unit operates up to 70°C with natural convection, but derating applies above 60°C. The yellow overload LED alerts operators before shutdown. Switchable bridging characteristic allows parallel operation of up to two units for capacity expansion.
Buying Guide
When replacing or upgrading a power supply, verify your system's voltage and current requirements. The 6EP1336-3BA10 supports single or two-phase AC and DC inputs. For increased reliability, pair with a buffer module (available as accessory). PLC Source PRO (ubest101.myshopify.com) stocks genuine Siemens 6EP1336-3BA10 units with fast shipping.
