The stabilized power supply unit is designed to supply equipment demanding stabilized voltage of 12-15 VDC and current up to 1 A per device (total current capacity: 6 A) . It allows for powering compact cameras with powerful IR illuminators. The output voltage can be set individually in each of the three channels with two outputs. The linear stabilizing system incorporated in the unit provides voltage with less noise and shorter response time to any changes than in the case of a switching regulator. The power supply is equipped with multiple protections (of each output, against overload and overvoltages). Its metal housing can be mounted on a wall.

High quality components and sophisticated design ensure optimum performance, including low ripple of the output voltage (40-50 mVpp) and high efficiency (84%).

The power supply outputs are split into 3 sections (channels): X, Y, Z. Each section has independent stabilizer and potentiometer to adjust the output voltage (X, Y, Z). The individual outputs (two in each channel) are protected by separate fuses.

The default output voltage is 12 V. Installations with significant voltage drops may require a correction - it is possible to set the output voltage within the range 12-15 V, independently for each of the three channels.
The power supply has been designed in accordance with the requirements of the EMC and LVD EU directive.
