DEIF Dan Control's LSU-112DG Load Distributor is a control unit used for generator load distribution and parallel operation, widely used in the control of diesel and gas generators.
###Product Features
-Load Distribution: The LSU-112DG is connected to the governor interface through an electronic potentiometer (such as EPQ96-2 or EPN-110DN) to achieve load distribution between generators.
-Parallel operation: Supports single machine mode operation (frequency control), parallel operation with the power grid (power control), and parallel operation with other power generation units (frequency and power control).
-* * Frequency and Power Control * *: Built in frequency and power transmitters, can be connected to external devices, supports constant power mode or constant speed mode.
-Unloading function: By unloading the input, the generator power can be adjusted to zero and disconnected from the parallel line.
###Technical specifications
-Measurement range:
-Current: 0.3A to 5.0A (AC).
-Voltage: 57.7V to 690V (AC).
-Frequency: 40Hz to 70Hz.
-* * Load Capacity * *:
-Current: Maximum 4 times rated current (continuous), 20 times rated current (10 seconds).
-Voltage: Maximum 1.2 times rated voltage (continuous), 2 times rated voltage (10 seconds).
-* * Working temperature * *:- 25 ° C to 70 ° C.
-Protection level: IP40 for shell and IP20 for terminal.
###Application scenarios
-Generator set control: Suitable for single or parallel operation of diesel generators and gas generators.
-Ship and Marine Engineering: Can be used for load distribution and parallel operation of ship power systems.
-Distributed power production: In a distributed generation system, ensuring load balancing among multiple power generation units.
###Installation and use
-Installation method: Supports 35mm DIN rail installation or base installation.
-Calibration and Setting: Calibrate through the built-in potentiometer to match different power generator sets.
-* * Connection method * *: Supports single-phase and three-phase measurement, and can choose built-in or external power transmitters according to the load type.
###Other characteristics
-* * LED indicator light * *: Provides status indicators such as power, uninstallation, and speed control.
-* * Self check function * *: Built in self check function to ensure the normal operation of the device.
-* * Multiple model options * *: DEIF also offers other models (such as LSU-113DG, LSU-114DG, etc.) with reverse power protection, automatic start stop and other functions.
The design and functionality of LSU-112DG make it an ideal choice for generator control and parallel operation, effectively improving the stability and reliability of the system.
