GensetPediaSpecifications per Jakson Genset's official "CPCB IV+" rating chart (2-page current specification sheet, jaksongenset.com). Jakson is a confirmed Cummins Genset OEM (GOEM) partner since 1982; every model uses a genuine Cummins base engine (DEF/SCR after-treatment inlet visible on the product photo confirms real CPCB IV+ hardware, not just a badge). Internally cross-checked: kWe/kVA ratio is exactly 0.8 power factor for all 36 rows in the source table (both this current "JSP-IV" line and a separate older "JSPF/JSP" line found in Jakson's general Distributed Energy brochure, not yet processed here) -- strong confirmation the table read correctly. No explicit "Prime"/"Standby" duty label is stated anywhere in this rating chart -- treated as Prime per this site's established convention for an unlabeled continuous rating. Several ratings (7.5, 10, 15, 25, 35, 50 kVA) are offered in both single-phase and three-phase configuration with identical kVA/kWe/BHP/dimensions/weight; this models the three-phase variant. 18.5/27.5/41 kVA are single-phase-only distinct catalog ratings, not phase variants of an already-listed number. "82.5-Comp" (X3.7-G12 engine) and "82.5" (QSB4.5-G1 engine) are two genuinely different physical products at the same kVA rating -- a compact line and a standard line -- modeled as separate rows. Alternator make/model, noise dB(A), control-panel model, and warranty terms are not stated in this rating chart and are left null rather than assumed. Engine model X2.6-G1 exactly matches a Cummins-branded genset already verified on this site (Cummins' own X2.6 series) -- cylinders/displacement inferred from that identical, independently-verified data, not independently restated by Jakson.
