Power supply BLOW 70-611# 12V 1.25A impulse (DIN-box) — compact DIN-rail compatible unit

Power supply BLOW 70-611# is a compact impulse (switch-mode) unit that provides a regulated 12 V DC output with a maximum current of 1.25 A. Designed for DIN-rail or enclosure mounting, this low-voltage supply is intended to power small electronic devices where stable 12 V is required. Its compact DIN-box form factor allows installation in constrained spaces and equipment cabinets while offering the functional characteristics expected from modern switch-mode power supplies.

Advantages

The BLOW 12 V 1.25 A impulse power supply delivers a steady 12 V output with efficient switch-mode conversion, offering a small footprint suitable for DIN-rail installations. It is built for reliable operation in compact enclosures and includes standard protections common to impulse supplies, such as overload and short-circuit handling and regulated output to maintain stable voltage under varying loads. Its compact design simplifies integration into CCTV, LED, and access control systems where space is limited.

Suitable for

• Powering small CCTV cameras and related surveillance modules
• Supplying LED modules and low-power lighting strips
• Feeding access control components, sensors and controllers
• Providing 12 V DC for small electronic devices and control boards

Key specifications

How to use

Install the unit inside an appropriate enclosure or onto a DIN-rail compatible mounting surface following local electrical codes. Connect the AC input to a suitably rated mains supply and observe correct polarity when wiring the 12 V DC output to the load. Allow for ventilation around the unit to ensure stable operation and avoid placing it near heat sources. Verify output voltage with a multimeter before connecting sensitive equipment and connect loads incrementally to confirm that the total current demand does not exceed 1.25 A.

Usage recommendations

Use appropriate circuit protection at the mains side and consider adding an inline fuse or circuit breaker sized for the installation. For prolonged reliable operation, keep cumulative load below the rated maximum and avoid exposure to extreme temperatures or moisture. When powering multiple devices, check combined current draw and use distribution wiring and connectors suitable for the total current.
