Power supply BLOW 70-623# 12V 2.08A DIN-box switching adapter

BLOW 70-623# is a compact switching power supply that provides stabilized 12 V DC output at up to 2.08 A. Designed for mounting inside a junction or flush box, this DIN-box style adapter supplies steady power to low-voltage devices such as LED strips, CCTV cameras, routers and other small electronics. The unit incorporates protection against short circuits and overloads and is engineered for typically low-noise operation in concealed installations.

Advantages

The adapter’s compact form factor allows installation inside standard junction boxes to keep wiring and electronics hidden. Built-in short-circuit and overload protection increases safety for connected equipment. Regulated output ensures stable voltage for sensitive low-voltage devices, reducing flicker in LED lighting and maintaining reliable operation of cameras and network devices. The switching design delivers efficient power conversion and a small footprint for constrained spaces.

Suitable for

• Powering 12 V LED strips and low-power LED modules
• Supplying 12 V CCTV and IP cameras with steady DC voltage
• Powering small routers, switches and IoT devices requiring 12 V
• Hidden installations inside wall junction or flush boxes

Key specifications

• Output voltage: 12 V DC
• Maximum output current: 2.08 A
• Output power: up to ~25 W
• Type: switching (SMPS) adapter suitable for concealed mounting
• Protections: short-circuit and overload protection
• Typical noise: low electrical noise suitable for sensitive devices

How to use

Install the power supply in a suitable junction or flush box with adequate ventilation and secure mounting. Connect the AC mains input according to local wiring regulations, ensuring correct live, neutral and earth/ground connections if required. Connect the 12 V DC output to the device(s) ensuring correct polarity and that the total load does not exceed the rated 2.08 A. After wiring, power on and verify stable 12 V output and correct device operation. If any protection trips, disconnect and inspect wiring and load before attempting to reuse.

Usage recommendations

Use cable of appropriate gauge for the expected current and keep total connected load below the rated maximum to ensure reliable operation. Install the adapter in locations that avoid direct exposure to moisture, excessive heat or poor ventilation. For long cable runs, consider voltage drop and compensate by using thicker conductors or placing the power supply closer to the load.
