Siemens 6EP33306SB000AY0 DIN Rail Power Supply
System Integration Context
This SITOP-equivalent unit mounts on a 35 mm DIN rail inside a control cabinet and provides regulated 24 V DC to a single load circuit. The record lists 600 mA maximum output current, adjustable output, and universal AC/DC input acceptance across 85–264 VAC or 110–300 V DC. Rated efficiency is 81 % at nominal input.

Adjustable output allows fine-tuning of the 24 V setpoint within the unit's regulation band to match downstream load requirements. The IP20 rating indicates protection against solid objects larger than 12.5 mm; no liquid ingress protection is claimed.
Agency Ratings
Certifications on record include CB, cCSAus, CE, CSA, cUL, cULus, and UL listings. Applications are listed as Hazardous Locations, Industrial, and ITE (Commercial). The hazardous-location listing covers equipment intended for installation in areas classified under applicable electrical codes; field verification against the specific Division/Zone requirements of the end installation is the installer's responsibility.
Engineering Verification Checklist
- Input voltage range matches available AC mains or DC source (85–264 VAC / 110–300 V DC)
- 600 mA output ceiling covers all connected loads with adequate design margin
- Adjustable output range satisfies downstream load voltage tolerance
- Hazardous-location approval scope (Division/Zone) aligns with the target installation classification
- Single-output topology meets branch isolation requirements
- IP20 rating is acceptable for the intended enclosure environment
- DIN rail mechanical mounting provisions are confirmed for the enclosure layout
- Output wire sizing and overcurrent protection coordinate with 600 mA rating
- Bulk packaging is suitable for the planned procurement and storage approach

| MPN | Output | Output Current (Max) | Efficiency | Input (AC) | Input (DC) |
|---|---|---|---|---|---|
| 6EP33306SB000AY0 | 24 V | 600 mA | 81 % | 85–264 VAC | 110–300 V DC |
| 6EP33106SB000AY0 | 5 V | 3 A | 76 % | 85–264 VAC | 110–300 V DC |
| 6EP33216SB000AY0 | 12 V | 1.9 A | 81 % | 85–264 VAC | 110–300 V DC |
| 6EP13215BA00 | 12 V | 2 A | 82 % | 85–264 VAC | 110–300 V DC |
All four units share the same Siemens series, IP20 rating, adjustable output, and universal AC/DC input. The 5 V / 3 A alternate is a lower output voltage with significantly higher current capacity and lower efficiency. The 12 V alternates offer intermediate voltage and current combinations within the same form factor family.
