Overview#
The Blue Star PS150-01 is a 150-kilowatt natural gas / LP standby generator built on the PSI (Power Solutions International) 8.8LTCAC turbocharged-aftercooled V8. It is rated 150 kWe standby on natural gas and 125 kWe on LP at 60 Hz / 1800 RPM. Available in single-phase (120/240V) and three-phase (120/208V, 240V, 480V, 600V) configurations. Controller is the DSE DCP7310. Fuel pressure requirement is 11 in. water column — standard utility service.
The PS prefix in Blue Star's model nomenclature denotes the PSI engine family. Larger Blue Star gaseous units use the NG prefix.
The PSI 8.8LTCAC V8#
PSI's 8.8L turbocharged-aftercooled V8 is a purpose-built stationary spark-ignition platform:
- Turbocharged-aftercooled (TCAC) — intercooled induction for power density at moderate displacement
- EPA Stationary Spark Ignition certified under 40 CFR 60 Subpart JJJJ
- 11 in. WC fuel pressure — compatible with standard utility NG service, no booster required
- 12V battery system — standard residential/light-commercial battery infrastructure
Voltage configurations#
| Voltage | Phase | Alternator | Connection |
|---|---|---|---|
| 120/240V | 1 | Stamford UCDI274J1 | 2-lead |
| 120/208V | 3 | Stamford UCI274G | 12-lead WYE |
| 240V | 3 | Stamford UCI274G | 12-lead DELTA |
| 277/480V | 3 | Stamford UCI274F | 12-lead WYE |
| 347/600V | 3 | Stamford UCI274F | 4-lead WYE |
All configurations carry ±1% voltage regulation. UL 2200, cUL, and CSA certifications apply across all voltage configurations.
Infrastructure requirements#
- Fuel pressure: 11 in. WC — standard utility residential/commercial NG service
- Ventilation: 12,000 CFM
- Coolant heat rejection: 301,260 BTU/hr; radiated: 189,000 BTU/hr
- Exhaust: 1,178 CFM at 1,350°F
When to spec the PS150-01#
- 125–150 kW standby loads on natural gas or LP, single- or three-phase
- Sites where standard 11 in. WC utility gas service is available (no booster required)
- Facilities requiring single-phase 120/240V output at this kW class
- Applications where UL 2200, cUL, and CSA certification are required across all voltages
Our service experience#
The PSI 8.8LTCAC platform is one we service across multiple brands at the 150 kW class, so the PS150-01 is functionally familiar despite the Blue Star packaging. Standard service items — spark plugs, air filter, oil and filter, ignition coils — cross-reference to PSI's published catalog. The DSE DCP7310 controller is the same unit found across Blue Star's current gaseous lineup, making programming and diagnostics consistent with their larger models.
