About
The ARK-MKA is a monoblock equipment for the regulation and monitoring of a spacecraft’s power supply system, specifically designed for high-orbit spacecraft. It was released in 2015 and has a guaranteed service life of 9 years. The estimated production/delivery time is 18 months. The equipment is unpressurized, meaning it is designed to work in a vacuum. It consists of several submodules: one charge-discharge device, two current regulators, one battery voltage control device, and three charge and discharge control devices. The design of the monoblock can be modified to increase its power output up to 10 kW by reconfiguring its internal submodules. It is planned for operation as part of a spacecraft for fundamental scientific space research. The system offers resistance to ionizing radiation of outer space up to 100 krad, provides an output DC voltage of 32 V, and has a power output of 700 W. Its mass is 12 kg, resulting in a power density of 58 W/kg. Cooling in vacuum is achieved via a heat cell board, and it uses a digital interface for commands and telemetry. The system is designed to work with nickel-hydrogen battery types.
