Power supply BLOW 70-613 12 V 2.08 A impulse/din-rail mount

BLOW 70-613 is an impulse switching power supply that delivers a stable 12 V DC output at up to 2.08 A. Intended for installation inside junction boxes or small enclosures with DIN-rail or surface mounting options, it supplies regulated low-voltage power for LED strips, CCTV cameras, access control modules and other 12 V devices. The unit incorporates protections typical for switching supplies to guard against short circuits and overloads while keeping a compact footprint for confined installation spaces.

Advantages

The compact design allows mounting in tight locations and small electrical cabinets. Regulated 12 V output provides consistent voltage for connected devices, reducing flicker and instability in lighting and ensuring reliable operation of cameras and modules. Built-in short-circuit and overload protection helps prevent damage to both the supply and connected equipment. The impulse switching topology offers efficiency and lower heat generation compared with linear alternatives.

How to use

Install the power supply inside a suitable enclosure or on a DIN rail according to local electrical codes, ensuring adequate ventilation and clearance from heat-sensitive components. Connect the AC input to the mains supply using proper wiring and secure terminals; then connect the 12 V DC output to the device(s) observing correct polarity. Verify the combined current draw of connected devices does not exceed 2.08 A. After wiring, apply mains power and confirm the output voltage is stable before finalizing the installation.

Usage recommendations

For reliable operation, avoid loading the supply beyond its rated current and provide adequate ventilation in the enclosure. Use appropriate fuses or circuit protection on the input and consider local surge protection if the installation is exposed to unstable mains. When powering multiple devices, distribute connections so that wiring losses are minimized and check output polarity before connecting sensitive electronics.
