Product description
The Siemens 6ES5-955-7NC11 is a power supply module from the SIMATIC S5 PS 955 series. Siemens assigns variant -7NC11 to the ZG 155H central controller. The supply input is 24 V DC; the permissible input range including ripple extends from 18 to 33 V DC. The catalog table specifies a rated input current of 14 A. Maximum inrush current is 100 A with an associated I²t value of 2.7 A²s. An adjustable stored-energy time of 5 or 20 ms is documented for a power failure. The module provides two galvanically isolated outputs. Output A1 supplies 5.1 V DC at 14 A and has a permissible current range from 0.2 to 14 A. Output A2 supplies 24 V DC at 0.1 A. Siemens specifies output-voltage tolerances of -0.5 to +2 percent at the 5.1-V output and -12.5 to +25 percent at the 24-V output. Separate floating contacts signal fan or battery failure. Main and reserve buffering each use a lithium battery rated 3.6 V and 1.9 Ah. Monitoring of the 24-V load input is not provided for this version. The documented 24-V auxiliary voltage supplies 1 A. Maximum power loss is 50 W; no fans are integrated. The two output circuits and buffering functions are listed separately in the Siemens data table. The exact order number 6ES5-955-7NC11, assignment to ZG 155H and electrical data distinguish this module within the PS-955 family. Documented dimensions are 40 × 255 × 205 mm. Siemens specifies an approximate weight of 1.3 kg.

Which input and output data are documented for the Siemens 6ES5-955-7NC11?
The input is documented for 24 V DC with a range from 18 to 33 V DC. The two outputs provide 5.1 V DC at 14 A and 24 V DC at 0.1 A.
How are buffering and status signals implemented in the power supply?
Main and reserve buffering each use a lithium battery rated 3.6 V and 1.9 Ah. Separate floating contacts signal fan and battery failure.
What applies if an item develops a defect within 14 days?
For the condition categories “Used, removed from an installation” and “New, old stock”, the contractual 14-day right of return in the event of a defect applies. The defect must occur within 14 calendar days after delivery and be reported in text form within the same period.
In particular, the REHA tamper-evident seal must remain fully intact and our RMA approval is required before return. In an accepted case, we decide between replacement and refund. Details in Section 11 of the Terms.
Which shipping methods and delivery times are available?
The shipping method, shipping cost and estimated delivery time are confirmed for the specific order. Depending on the item, destination and urgency, we can check parcel, express or freight shipping as well as collection.
A delivery date is binding only if we expressly confirm it as binding.
Which payment terms apply?
The payment terms stated in the checkout or order confirmation apply. Depending on the order and customer, payment is made in advance or against invoice.
International deliveries and deliveries to new customers are generally made against advance payment unless we expressly confirm another payment arrangement.
Can I return an item ordered incorrectly or found incompatible?
No. There is no general B2B right of return, exchange, cancellation or withdrawal. Incorrect or duplicate orders and a lack of suitability or compatibility with the customer’s installation are not covered by the contractual 14-day right of return in the event of a defect. Details in Section 12 of the Terms.
Can I request individual pricing for several items?
You may request an individual quotation for several items or larger quantities. We then check availability and pricing for the specific requirement; there is no entitlement to a quantity discount. Open the quick enquiry.
Do you also purchase industrial spare parts?
Yes. You can offer us automation and drive components for purchase. Please provide complete type numbers, quantities, condition details and photographs where possible.
After review, we will tell you whether a purchase is possible and on which terms. Learn more about selling industrial stock.
