Control panel
KG640C microprocessor-based genset controller (stated "only for 6K Engine" in this document): graphical LCD display, phase voltages/currents, frequency, kVA/kW/kWh/kVAr, power factor, canopy temperature (optional), lube oil pressure, engine temperature, RPM, run hours, number of starts, fuel level, auto/manual stop, battery charge condition, AMF feature; diagnostics for battery charging failure, over/under speed, over current, over/under voltage, over kW, phase sequence/missing, mains under voltage, earth fault trip, low fuel level, low lube oil pressure, high engine temperature, low/high battery voltage, over-crank protection, routine maintenance indicator, genset test facility, mains frequency; optional Modbus communication
Specifications per Kirloskar Oil Engines Ltd (Kirloskar Powergen)'s official "200-250 kVA CPCB IV+ Compliant" SL Series technical specification catalogue (print code 20240610/REV01/A4). Sourced from the open web (kirloskaroilengines.com) as part of a targeted search for the site's remaining zero-model brands. Verified via bore x stroke x cylinder-count vs. stated displacement cross-check (105x125mm x 6-cyl = 6.494L, matches stated 6.48L within rounding) -- same bore/stroke as the 160 kVA row's engine but a different generation suffix (4G2 vs 4G1) and a higher rated output (183.8kW vs 147.1kW), a genuine retune, not a duplicate. Battery starting voltage is 12V for this rating specifically (vs 24V for 250 kVA in the same document) -- explicitly stated as different per-column, not a shared value. Rated Prime only -- no Standby figure given. DOC+SCR aftertreatment with DEF/AdBlue dosing (45L tank, ISO 22241, larger than the 82.5-160 kVA range's 25L). This document explicitly states "Controller KG640C is only for 6K Engine" -- confirms the controller assignment is engine-specific, not size-generic. Noise (75 dBA) is the document's own stated design ceiling. Two weight figures given (Dry, Wet w/o fuel) -- uses Dry. No fuel-consumption LPH or warranty/price figure stated.
