Features:
- 6EP1333-3BA00 supplies a regulated 24 V DC rail at a 5 A rating.
- A de-energized selector aligns the converter with the available AC source range.
- Front switches choose single or parallel behavior and the overload response.
The 6EP1333-3BA00 links a one- or two-phase feeder to an isolated DC load circuit.
Its duplicated positive and negative terminals distribute one regulated output rather than independent channels.
Selector position, characteristic switches and LED state provide three separate checks before load troubleshooting begins.
The Siemens 6EP1333-3BA00 SITOP PSU200M Stabilized Power Supply may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Matching the selector to the incoming AC feed
- Low range: The first path accepts 85–264 V AC.
- High range: The second path accepts 176–550 V AC.
- Switch state: The factory position is 230 V and the selector is moved only while de-energized.
- Two-phase feed: Line conductors use L1 and N/L2 with the protective conductor on PE.
What switches A and B change
- Switch A off: The hard characteristic holds voltage independently of output current in single operation.
- Switch A on: The soft characteristic allows current sharing during parallel operation.
- Switch B off: Constant-current mode reduces voltage as overload passes the current limit.
- Switch B on: Latching mode shuts the supply down when overload pulls the output below 20 V.
Separating normal, overload and shutdown states
- Green indication: Output voltage is above 20 V ±0.5 V in normal operation.
- Yellow indication: Overload has reduced the output below the 20 V threshold in constant-current mode.
- Red indication: Latching shutdown or remote switch-off is present with the signaling module.
- No green LED: The unit has no supply voltage at its input.
Relating voltage adjustment to current and cooling
- Factory setting: The output is supplied at 24 V DC.
- Adjustment span: The potentiometer raises the setting as far as 28.8 V.
- Current derating: Above 24 V, permitted output current falls by 4% for each additional volt.
- Thermal alternative: The allowable ambient temperature may instead be reduced by 3 °C for each additional volt.
