Power supply BLOW 70-601# switching 12 V 1.25 A for flush-mount installation

BLOW 70-601# is a switching power supply that provides a regulated 12 V DC output at 1.25 A, designed for flush-mount installation. Its compact form factor allows mounting inside standard junction boxes and recessed housings, delivering stable low-voltage power for LED lighting, access control modules, sensors and small electronic devices. The unit uses impulse (switching) conversion to maintain output voltage under varying load conditions while minimising size and heat generation.

Advantages

The switching topology ensures efficient energy conversion and reduced heat compared with linear supplies. Designed for flush-mount installation, the power supply fits into limited spaces and keeps the installation neat. Regulated 12 V DC output provides stable voltage for sensitive electronics, and the 1.25 A maximum current supports multiple small loads or a single moderate load. The compact housing and standard terminal connections ease wiring and replacement in existing installations.

Suitable for

• LED strips and small LED fixtures requiring 12 V DC
• Access control panels, card readers and strike release devices
• Sensors, detectors and low-power surveillance accessories
• Small electronic devices and control modules in residential and commercial installations

Key specifications

• Output voltage: 12 V DC regulated
• Maximum output current: 1.25 A
• Topology: switching (impulse) power supply
• Mounting style: flush-mount / recessed installation suitable for junction boxes
• Application: low-voltage supply for lighting and control electronics
• Form factor: compact housing for space-constrained installations

How to use

Mount the unit inside a compatible flush-mount junction box or recessed housing according to local electrical regulations. Connect the AC input to the mains supply using proper wiring and protective devices, and connect the 12 V DC output to the load observing correct polarity. Ensure that the total connected current does not exceed 1.25 A and allow for ventilation around the housing if installed in thermally restrictive enclosures. Verify output voltage with a multimeter before connecting sensitive equipment.

Usage recommendations

Use the power supply with loads that draw less than the rated 1.25 A to ensure reliable operation and longer service life. Install a circuit breaker or fuse on the AC input side and consider adding short-circuit protection on the DC output if the connected devices lack it. For installations driving multiple LED modules, calculate combined current draw including inrush currents to avoid overload. Follow local electrical codes and manufacturer guidance for mounting and wiring.
