ELECTRONIC CONTROLLER Russian patent published in 2025 - IPC H02H3/12 H02H1/00 F25B49/00 

FIELD: electronic equipment.

SUBSTANCE: invention relates to an electronic controller for refrigerating machines. Controller comprises a power supply unit, a connector for connection to a load, a microcontroller connected to the power supply unit and the connector, which controls the supply voltage to the connector, and a measuring device for measuring current flowing through the connector and voltage on the connector. Connector contains relays connected to the microcontroller, which are triggered after receiving commands for powering the load. Microcontroller is connected to the measuring device, and is configured to reduce the supply voltage to zero, if after supply of said supply voltage the measuring device does not detect current flowing through the connector. Microcontroller processes current and voltage signals received from the measuring device to estimate power or energy consumed by the load, and compares the predetermined control values, depending on the monitored load, with the current consumed by the load to determine whether the load operates in the expected conditions.

EFFECT: increased energy efficiency at connected load.
