PRODUCT OVERVIEW

PS 407 power for S7-400 racks

Siemens 6ES7407-0KA02-0AA0 is a SIMATIC S7-400 PS 407 power supply with a wide-range 120/230 V AC or DC input. It provides 5 V DC at up to 10 A for the S7-400 backplane bus and 24 V DC at up to 1 A. The module occupies two rack slots, supports power-failure buffering and includes short-circuit protection.

Wide-range input 85 to 264 V AC or 88 to 300 V DC	Backplane capacity 10 A at 5 V DC with no base load required
Industrial protection Primary/secondary separation and Class I protective conductor	Compact rack format 50 mm width in a two-slot S7-400 module

Applications

SYSTEM ROLE

Applications

S7-400 central rack power Converts wide-range plant supply power into the regulated backplane voltages required by SIMATIC S7-400 modules.	High-load configurations The 10 A backplane rating supports racks whose calculated 5 V load exceeds lower-current PS 407 variants.
AC or DC supply sites Suitable where the available source is 120/230 V AC or 120/230 V DC within the specified wide input ranges.	Process continuity The 20 ms energy reserve helps bridge short supply interruptions and meets the stated NAMUR buffering recommendation.

Construction

MECHANICAL DESIGN

Construction

Rack footprint 50 mm wide, 290 mm high and 217 mm deep; requires two S7-400 rack slots.	Input termination 3 x 1.5 mm2 solid or stranded conductors with end sleeves; cable diameter 3 to 9 mm.
Electrical isolation Primary and secondary circuits are separated; overvoltage category II and pollution degree 2.	Backup provision Optional 3.6 V lithium AA battery provides backup support specified for the module.

Installation

FIELD PRACTICE

Installation

1. Rack planning	Reserve two adjacent S7-400 slots and verify the 50 x 290 x 217 mm envelope.
2. Load calculation	Confirm the rack requires no more than 10 A at 5 V DC and 1 A at 24 V DC.
3. Supply check	Verify AC input is 85 to 264 V or DC input is 88 to 300 V before energizing.
4. Protective conductor	Install the Class I protective conductor and use the specified conductor size and cable diameter.
5. Commissioning	Check rack power indication and downstream module status after power-up.

Selection

ENGINEERING CHECK

Selection

Input source Select PS 407 for the documented 120/230 V AC/DC source range.	Backplane demand Use the 10 A version only after calculating the total 5 V rack current.
Mechanical fit Confirm two free rack slots and the 50 mm module width.	Order identity Match the complete article number 6ES7407-0KA02-0AA0 on quotation, carton and nameplate.

FAQ

BUYER AND ENGINEER CHECKLIST

FAQ

Q1. How can a buyer verify the exact quoted model?

Require the full article number 6ES7407-0KA02-0AA0 on the quotation and compare it with current photos of the module label and carton label. The KA02 and 0AA0 suffixes are part of the order identity.

Q2. How can New, Used and Refurbished stock be distinguished?

Ask for dated high-resolution photos of seals, terminals, housing, mounting points and the nameplate. A qualified supplier should state the condition in writing and disclose any opened packaging, prior installation or repair work.

Q3. How should a purchaser evaluate supplier reliability?

Check the legal company name, business registration, company-domain email, bank-beneficiary consistency, traceable quotation number and documented inspection process before payment.

Q4. Which specifications must an engineer confirm before ordering?

Confirm the 120/230 V AC/DC supply, 85 to 264 V AC or 88 to 300 V DC permitted range, 5 V/10 A and 24 V/1 A outputs, two-slot requirement and 50 x 290 x 217 mm dimensions.

Q5. What evidence should be requested before payment?

Request current photos of the exact nameplate, front panel, input terminals, rear connector and packaging, plus a video or inspection record showing consistent serial or identifying marks.

Q6. Can a similar PS 407 or a different suffix be substituted?

Do not treat a similar PS 407 as automatically interchangeable. Verify input range, output-current rating, slot use, dimensions, backup functions and complete order suffix.
