Power supply BLOW 70-757# switch-mode mounting 12 V 3 A 36 W

Switch-mode mounting power supply BLOW 70-757# provides a stabilized 12 V DC output with a maximum current of 3 A (36 W). Designed for fixed installation, this compact unit supplies low-voltage power to LED strips, CCTV cameras, routers and other 12 V devices. The mounting enclosure and screw terminals simplify wiring and integration into electrical cabinets and local installations where a reliable, regulated 12 V source is required.

Advantages

This power supply delivers a stable 12 V output with short-circuit and overload tolerance characteristic of modern switch-mode designs. Its compact mounting housing reduces required installation space and allows easy attachment to panels or DIN-rail-compatible surfaces. Low no-load consumption and thermal protection improve operational reliability, while screw terminal connections provide secure wiring for permanent installations.

Suitable for

• Powering LED strips and small LED lighting circuits
• Supplying CCTV cameras and access control devices
• Providing stable power to routers, switches and network equipment requiring 12 V
• Use inside electrical cabinets, distribution boxes and custom enclosures

Key specifications

• Output voltage: 12 V DC regulated
• Maximum output current: 3 A
• Maximum output power: 36 W
• Input: switch-mode AC mains operation (universal input range typical for similar units)
• Mounting: fixed mounting enclosure suitable for panel or cabinet installation
• Connections: screw terminal outputs for secure wiring
• Protection features: overload and short-circuit protection; thermal protection

How to use

Mount the power supply inside a dry, ventilated electrical cabinet or on a secure panel using the provided mounting points. Connect the AC mains input following local wiring regulations and ensure power is switched off during installation. Attach the 12 V DC load to the screw terminals with correct polarity and verify connection tightness. After wiring, apply mains power and confirm the output voltage with a multimeter before connecting sensitive devices.

Usage recommendations

To ensure long service life, avoid operating the unit beyond its 3 A rating and allow adequate ventilation around the housing. Where multiple devices draw power, calculate combined current consumption and include a safety margin. Use appropriate fusing on the DC output and follow local electrical codes for permanent installations.
