Power Supply Sigma-15SK - «Communication and Radionavigation SPB» Company

Power Supply Sigma-15SK is intended to ensure uninterrupted power electronics, automation and telemetry, radio communications and repeaters due 13.8V stabilized DC voltage and current up to 15A. Sigma-15SK is ideal for remote and unmanned supply telemetry and automation, communication relays and other electronic equipment.

The power supply is made in the case of aluminum alloy. According to the degree of protection against environmental influences the power supply is made in the performance of IP53 in accordance with GOST 14254-96. Power supply 220 VAC and voltage converter 24/12 are separate and structurally independent modules combined into a single unit.
