Description
The HYUNDAI HEEM-3 Motor Auto Control Unit is a marine automation controller designed for automatic motor control, standby changeover, and sequential start functions in ship auxiliary machinery systems. It is part of the HEEM Motor Automatic Control System series and is mainly used for controlling multiple auxiliary motors such as pumps and other essential marine equipment.
The HEEM-3 controller provides automatic changeover operation between running and standby motors. When the operating motor experiences abnormal conditions such as overload, power loss, or low-pressure conditions, the system can automatically start the standby motor to maintain continuous equipment operation.
Designed for marine switchboard and engine room automation applications, the HEEM-3 reduces complex relay wiring by using solid-state control technology, improving system reliability and simplifying maintenance procedures.
