The LSU series is a control unit for control of the prime mover in a power unit. The LSU can control the power unit : - in stand-alone mode, performing frequency control - parallel with grid, performing power control - parallel with other power units, performing frequency and power control The unit is designed for connection to a mechanical speed governor, however in conjunction with the DEIF electronic potentiometer type EPN-110DN or EPQ-96 it can control electronic speed governors as well. LSU Options: - LSU-112DG: Standard Load Sharing - LSU-113DG: Load Sharing including reverse power protection and low power detection - LSU-114DG: Load Sharing and automatic Start/stop outputs - LSU-122DG: VAr Load Sharing inclusive AVR control The LSU series has a built-in frequency transducer. If a very stable frequency is wanted, an external frequency transducer common for all the LSUs in the power plant can be connected. If a number of power units are to be synchronised to the busbar at the same time, the frequency may likewise be controlled externally. Regulator output : The unit is provided with two contact outputs for speed control: Power and frequency control: The regulating speed of the servomotors for the prime mover is controlled by the built-in P controller of the LSU according to its setting for: -TN (min. ON time): The min. duration of the control pulse when inside the proportional band Xp. - XP (proportional band): The zone within which the pulse/pause ratio changes proportionally to the frequency/power deviation from the required value. - TP (period time): The time between the beginnings of two subsequent relay pulses. - Deadband: The zone within which no control pulses are emitted. Feattures : - For control of diesel and gas generators - Built-in power and frequency transducer - Constant power or isochronous mode - LED indication of status - LED indication for activated control - 35 mm DIN rail or base mounting Borna Niroo Karan (Bornika) is the exclusive agent of DEIF in the fields of consultation , sales and distribution of power industry products including Load sharing unit products .
