DEIF LSU‑112DG Active Load Sharing Unit P/N 100031593.1

Technical Specifications

Model:100031593.1(LSU‑112DG)

Brand:DEIF

System compatibility:Uni‑line series active‑power load‑sharing unit,part number 100031593.1. Cooperates with synchroniser FAS‑113DG / HAS‑111DG and governor electronic potentiometer. Applied for marine and industrial multi‑genset parallel power‑station. Without built‑in reverse‑power protection,select LSU‑113DG if reverse‑power trip function is required.

Function:Hardware analogue load‑sharing controller. Measures generator three‑phase AC voltage and CT secondary current. Realises proportional active‑power distribution among paralleled gensets;supports standalone frequency control,isochrone operation and constant‑power mode. Provides relay increase/decrease outputs for engine governor adjustment. Front‑panel potentiometers adjust proportional range Xp,minimum pulse time Tn and derating parameters. No PC configuration software required,all parameters set locally by potentiometers.

Installation:35 mm DIN‑rail mounting or base screw mounting inside switchgear cabinet

Interface:

‑Screw terminal:three‑phase PT voltage input,CT current input

‑Relay output:SG increase / SG decrease for governor control

‑Analogue parallel bus terminals PS / FS

‑Unload input,status signal output terminals

‑Front‑panel potentiometers and LED status indicator lamps

Circuit feature:Analogue measuring circuit,surge suppression for AC measuring inputs,parallel bus automatic disconnection under power‑loss condition,relay contact transient protection.

Feature:Marine classification approved;relay contact rating 250VAC / 24VDC,8A resistive load. Classic end‑of‑life Uni‑line spare part. Distinguished from LSU‑113DG:no reverse‑power and low‑power protection function.

Diagnostic:Front‑panel LED indicates power supply,voltage detection and control‑active status;fault status output contact opens under power‑loss or internal failure.

Power supply:24VDC(18‑32VDC),typical power consumption 2.5W

Protection class:IP20

Horizontal operating temperature:‑25℃ ~ +70℃

Storage temperature:‑40℃ ~ +85℃

Relative humidity:5%‑95% non‑condensing

Shock & vibration:Complies with DNV marine environmental requirement

Weight:0.74kg

Dimensions:145mm ×110mm ×75mm

Certification:DNV,CE,marine type approval

Built‑in function

100031593.1(LSU‑112DG) load‑sharing unit balances active‑power for multi‑generator parallel power‑station. It outputs relay adjust pulses to engine governor to realise even load distribution among paralleled gensets. Widely used for marine and industrial generator parallel switchgear cabinet spare‑part replacement.

Product Brief

100031593.1 is DEIF part number for LSU‑112DG,Uni‑line series active‑power load‑sharing unit without reverse‑power protection. Parameters adjusted by front‑panel potentiometers without configuration software. When reverse‑power protection function is needed,please choose LSU‑113DG. Widely applied for genset parallel cabinet maintenance and renovation. ESD anti‑static protection shall be followed during installation.
