PowerCommand 1.1 Electronic Control System

The RS100 includes Cummins’ advanced PowerCommand 1.1 control system, which provides:

• Automatic start and stop

• Output metering

• Fault detection and auto shutdown

• NFPA 110 Level 1 capability (with proper installation)

• Field-adjustable mainline breaker (125–400 amps)

Voltage is regulated to ±1% and frequency to 0.25% at 60Hz. This precision matters for:

• Sensitive electronics

• Medical equipment

• Data centers

• Manufacturing automation

When compared to smaller single-phase options like the
Cummins 36kW Quiet Connect 120/240 Volt Single Phase,
the RS100’s 3 phase system offers superior load balancing and efficiency for commercial environments.

Natural Gas or Propane Generator Flexibility

The Cummins RS100 Quiet Connect 100kW Generator 120/208 Volts 3 Phase supports both:

• Erdgas (NG)

• Flüssigpropan (LP)

Fuel selection is field-configurable.

Kraftstoffverbrauchswerte:

Erdgas

• 1317.7 cubic feet/hour (full load)

• 805.4 cubic feet/hour (half load)

Propan

• 14.25 gallons/hour (full load)

• 8.57 gallons/hour (half load)

This dual-fuel flexibility allows facility managers to select the most stable and cost-effective fuel source available locally.

---

Quiet Connect Sound-Level Design

Despite its 100kW capacity, the RS100 operates at approximately 73 dBA.

The Sound Level 1 enclosure provides:

• Reduced neighborhood disturbance

• Improved compliance in mixed-use zones

• Lower operational noise for commercial campuses

For higher-voltage three-phase needs, you may also evaluate the
Cummins 36kW Quiet Connect Series RS36 277/480 Volts 3 Phase,
which supports alternative voltage configurations for specific industrial requirements.

Installation Requirements and Site Preparation

The RS100 requires:

• Prepared concrete slab

• Professional installation

• Proper gas line sizing

• Automatic transfer switch integration

• Code-compliant electrical connections

Practical installation steps:

1. Conduct load calculation and demand analysis

2. Confirm utility gas capacity

3. Prepare reinforced slab foundation

4. Install automatic transfer switch (ATS)

5. Commission system with certified technician

Expert recommendation: Always oversize slightly beyond calculated peak load to allow future expansion and reduce strain during startup surges.

Anwendungsbeispiel aus der Praxis

A multi-tenant commercial building requiring 85kW continuous load installed the Cummins RS100 with automatic transfer switch integration. During a grid outage, the generator restored power within seconds, maintaining elevator operation, lighting systems, refrigeration units, and security systems without interruption.

Voltage fluctuation remained within ±1%, preventing damage to sensitive electronics.

This is where commercial-grade standby generators separate from light-duty residential units.
