The “SL10” likely refers to the PULS SL10 DIN rail power supply series from PULS POWER GmbH. These power supplies are designed for various applications and come in 1-phase (like the SL10.101 and SL10.104) and 3-phase (like the SL10.300) versions. They offer features like switchable input (115/230 V), high efficiency, and power reserves.

Different Models:

The series includes both single-phase (SL10.101, SL10.104) and three-phase (SL10.300) models.
115/230V Switchable Input: The SL10.104, for example, has a switchable input voltage for flexibility.
High Efficiency: Some models achieve up to 87% efficiency, making them energy-efficient.
Power Reserves: They offer 20% power reserves to handle short-term peaks in load requirements.
Full Output Power: They can provide full output power between 0 and +60°C.
DIN Rail Mount: As DIN rail power supplies, they are designed for easy installation in electrical enclosures.
