Power supply BLOW 70-612# 12 V 1.67 A — impulse/din-rail style for low-voltage devices

BLOW 70-612# is an impulse (switching) power supply that provides a stabilized 12 V DC output at up to 1.67 A. It is intended for powering low-voltage electronic devices such as CCTV cameras, LED modules and network equipment. The unit features a compact DIN-rail style form factor designed for installation inside distribution boxes or electrical enclosures, and uses standard screw terminals for mains input and low-voltage output wiring.

Advantages

The switching topology delivers consistent 12 V DC output with relatively high efficiency and reduced heat generation compared with linear supplies. Its compact DIN-rail compatible housing simplifies mounting inside cabinets and switchrooms, saving space. Standardised input/output terminals allow straightforward installation and replacement in existing systems. The stabilized output helps protect connected low-voltage devices from mains fluctuations within the device's regulation range.

Suitable for

• Powering 12 V CCTV cameras and recording equipment
• Supplying 12 V LED lighting modules and strips
• Providing power for 12 V routers, modems and network peripherals
• Small control panels and sensors requiring a stable 12 V source

Key specifications

• Output voltage: 12 V DC stabilized
• Maximum output current: 1.67 A
• Power delivery: approximately 20 W
• Topology: switching (impulse) power supply
• Mounting: DIN-rail compatible compact housing for enclosure installation
• Connections: screw terminals for mains input and low-voltage output

How to use

Install the power supply on a compatible DIN rail inside an appropriate distribution box or metal enclosure, ensuring adequate ventilation and compliance with local electrical codes. Connect the mains input to the designated input terminals with proper protective devices (fuse or circuit breaker) as required by local regulations. Connect the 12 V DC output to the device or distribution bus using correct polarity and secure wiring. Verify output voltage with a multimeter before connecting sensitive equipment. Allow a brief stabilization period after powering on before attaching loads.

Usage recommendations

Place the unit in a ventilated enclosure and avoid mounting near heat sources. Use wires sized for the output current to minimize voltage drop, and add a centralized fuse or overcurrent protection on the DC output where multiple devices are powered. For critical loads, consider adding an uninterruptible power supply or battery backup downstream of this power supply.
