Siemens SITOP Series Buffer, 20-30V Supply Voltage, 40A Supply Current - 6EP42317HC000AX0

This buffer provides a DC buffering function for industrial control installations, designed for DIN-rail mounting in automation and power-distribution environments. It operates within a defined low-voltage DC range to support continuity of control signals and power sequencing, and it is suitable for systems requiring robust electromagnetic immunity.

Features and Benefits:

• Operates from 20V to 30V for flexible DC inputs
• Supplies up to 40A to handle high-current loads
• Withstands ambient temperatures down to -40 °C for cold conditions
• Rated for operation up to 70 °C for elevated-temperature sites
• Conforms to EN 61000-6-2 for industrial electromagnetic immunity

Applications

• Suitable for 24V DC control-power hold-up in machinery
• Used with DIN-rail power-distribution enclosures
• Ideal for buffering DC supplies in automation cabinets
• Can be used for high-current relay and contactor drive support

What mounting arrangement is required for installation?

It fits onto standard DIN-rail hardware to integrate with common control-panel layouts.

How does the device behave under high ambient temperatures?

It continues to operate up to 70 °C ambient, allowing placement near heat‑generating components.

What input supply range must be provided for reliable operation?

A DC supply between 20V and 30V is required to meet specification limits.

What level of surge or electromagnetic disturbance immunity is addressed?

The unit meets EN 61000-6-2, providing immunity suitable for industrial electromagnetic environments.
