The brackets are made of 1.5mm thick sheet steel and painted black with powder paint. One bracket accepts one or two power supplies, depending on the bracket model. The power supplies are attached to the bracket using two adapter brackets. The corners are screwed to the lugs of the radiators of the power supplies located closer to the front panel of the device. Each radiator bump has two M4 threaded holes. The bracket is screwed in with two M4x10 screws. Further, these corners together with the power supply are screwed to the bracket with M4x10 screws. To do this, in the plane of the corner facing the bracket, there are two holes with M4 threads. Sketches of the brackets with dimensions and drawings explaining the installation of the power supplies on the bracket are included.

The power supply is designed to provide uninterrupted power supply of electronic equipment, security and fire alarm systems, video surveillance, radio communications and communication repeaters - with stabilized constant voltage of 13.6 V and current up to 10A. Ideal for powering fire alarm and video surveillance systems, as well as other electronic equipment where uninterruptible power supply is required. The power supply is installed in a metal box, which provides space for a battery with a capacity of up to 12 Ah. The degree of protection of the power supply according to GOST 15254 (IEC 529) is IP20. The source belongs to class 1 of protection against electric shock according to GOST IEC 60950-1 and GOST IEC 61204-7. The source design meets the fire safety requirements in accordance with GOST 12.1.004. Type of climatic modification UHL 2 in accordance with GOST 15150.

The DC / AC-24/12 voltage converter is designed to power dome cameras or other electronic equipment in the TREK power supply system, with an alternating voltage of 24V, with a power consumption of up to 40W. It can be used in other applications outside the TREC system. The converter is powered from a direct current source with a voltage of 18 to 30V. The DC / AC - 24/24 converter converts direct voltage 24V (18-30V) coming from power sources of the K-307-05 or K-307 series -10 (or similar in parameters) to an alternating (pure sine) voltage - 24V. The converter is implemented on the principle of high-frequency pulse energy conversion and is made without galvanic isolation. According to the degree of protection against environmental influences, the converter is manufactured in the IP65 version according to GOST 14254–96.
