Applications

APPLICATIONS

6EP3331-6SB00-0AY0

Official product-specific information

LOGO! controller supply

Provides stabilized 24 V DC power for LOGO! controllers and compatible low-voltage automation loads.

Small distribution boards

The 36 mm stepped-profile housing supports compact installation in distribution-board layouts.

Control-panel auxiliaries

Suitable for sensors, relays and other 24 V DC auxiliary circuits within the rated 1.3 A output.

Availability expansion

Can be combined with suitable SITOP DC UPS, redundancy and selectivity modules when the 24 V system design requires higher availability.

Functions

FUNCTIONS

6EP3331-6SB00-0AY0

Official product-specific information

Wide-range conversion

Accepts a broad AC input range and also permits DC input operation for flexible supply-system integration.

Voltage adjustment

The front potentiometer provides a 22.2-26.4 V setting range for compensating distribution voltage drop.

Startup reserve

Delivers up to 1.95 A for 200 ms to support short startup current demand.

Parallel operation

Parallel connection is permitted when the engineering rules in the Siemens LOGO!Power documentation are followed.

Protection

PROTECTION

6EP3331-6SB00-0AY0

Official product-specific information

Electronic short-circuit protection

The output uses an electronic constant-current characteristic under short-circuit conditions.

Input fuse

Internal fuse protection is provided; Siemens recommends a feeder miniature circuit breaker from 6 A characteristic B or 2 A characteristic C.

Touch protection

The enclosure is rated IP20 for installation inside a suitable cabinet or distribution board.

Thermal derating

Above +55 °C, reduce available output at 2% per kelvin up to the specified +70 °C ambient limit.

Installation

INSTALLATION

6EP3331-6SB00-0AY0

Official product-specific information

DIN-rail mounting

Install in the standard upright mounting position on the specified rail system inside an enclosure.

Mechanical envelope

Allow for the 36 × 90 × 53 mm housing and a 36 × 130 mm installation envelope.

Ventilation clearance

Maintain at least 20 mm clear space above and below the unit for cooling.

Wiring terminals

Use the L/N input and +/- output screw terminals with conductors from 0.5 to 2.5 mm².

FAQ

6EP3331-6SB00-0AY0

Product verification and procurement guidance

Q1. How can the exact quoted model be verified?

Match 6EP3331-6SB00-0AY0 on the quotation, device label and packaging. The official description must state LOGO!Power, 100-240 V AC input and 24 V DC / 1.3 A output.

Q2. How can New, Used or Refurbished condition be distinguished?

Request clear photos of the Siemens label, housing, terminal screws, potentiometer and packaging. Installation marks, scratched terminals, damaged DIN-rail clips or missing seals can indicate previous use.

Q3. How should the supplier be checked before purchase?

Verify the supplier legal registration, company payment account and traceable contact details, then require a written quotation that states the complete order number and official electrical ratings.

Q4. Which specifications should engineering verify?

Confirm the 100-240 V AC input, 24 V DC / 1.3 A output, 22.2-26.4 V adjustment range, 36 × 90 × 53 mm dimensions, 0.12 kg weight, IP20 rating, terminal size and temperature derating.

Q5. What physical evidence should be requested before payment?

Ask for dated photos of the full label, both terminal blocks, front potentiometer, DIN-rail clip and unopened packaging, plus a photo showing 6EP3331-6SB00-0AY0 clearly.

Q6. Can a similar LOGO!Power model be substituted?

Not automatically. Related 24 V models differ in output current, enclosure width and installation capacity, so the exact current demand, protection and panel space must be checked first.
