Applications
The MEAN WELL SCP-75-12 may be suitable for compatible applications such as:
– Float charging of 12V battery systems
– Battery-backed electronic equipment
– Industrial control equipment with battery backup
– Compatible standby power arrangements
– Electronic systems requiring a suitable 13.8V DC charging supply
Check battery chemistry, charging requirements, and manufacturer recommendations before using this power supply. It should not be assumed suitable for every 12V battery type or charging method.
Installation and Buyer Guidance
Before ordering, verify the complete model number **SCP-75-12** and confirm that the required output is 13.8V DC. This is a battery-charging power supply, not a conventional fixed 12V output supply.
Use a compatible external NTC thermistor if temperature compensation is required. Follow the manufacturer’s instructions for wiring, battery polarity, fusing, ventilation, and output adjustment. Install the unit inside a suitable enclosure with sufficient clearance for free-air convection.
Electrical connections should be completed by a qualified professional according to the manufacturer’s documentation and applicable electrical safety standards.
