Power supply BLOW 70-758# switching bench/rail-mounted 12V 5A 60W

Switching power supply BLOW 70-758# delivers a regulated 12 V DC output with a maximum current of 5 A and total power up to 60 W. Designed for installation in electrical enclosures or for DIN-rail and flat-surface mounting, this unit provides a compact and reliable source of low-voltage power for a range of devices such as CCTV cameras, LED lighting modules, access control equipment and automation controllers. The supply includes standard switching power supply protections and is intended for professional installation in industrial and commercial applications.

Advantages

The switching topology ensures compact size, high efficiency and low heat generation compared with linear supplies. Built for bench, panel or DIN-rail mounting, the enclosure and mounting options provide flexible installation in cabinets or on rails. Built-in protection features help guard against overload, short-circuit and thermal stress, supporting stable operation of connected 12 V devices. The supply also offers steady voltage regulation to minimise flicker or performance issues in sensitive electronics.

Suitable for

• 12 V CCTV camera systems and recording equipment
• LED strips and fixed lighting installations requiring 12 V DC
• Access control panels, card readers and door actuators
• Industrial controllers, sensors and low-voltage automation modules
• Field and bench power for installation, testing and maintenance tasks

How to use

Install the power supply in a well-ventilated electrical enclosure or mount it on a DIN rail or flat surface according to the mounting holes and rail clip provided. Connect the AC mains input to the designated terminals following local electrical codes and ensure correct fuse protection on the mains side. Connect the 12 V DC output to the load, observing polarity and total current limits to avoid overloading. Allow adequate spacing around the unit for convection cooling and verify output voltage under load conditions. During commissioning, check that protection functions operate correctly by inspecting indicator LEDs or measuring output under defined fault conditions if necessary.

Usage recommendations

Use appropriate wiring rated for the expected current and secure all terminal connections. If multiple devices draw near the rated current, distribute loads or use separate supplies to maintain reliability. Ensure the enclosure provides sufficient ventilation and consider placing the supply away from heat sources. Periodically inspect connections and ambient conditions to prevent dust build-up and overheating. Follow local electrical regulations and safety practices when installing and servicing the unit.
