Generac Power Systems RD04833A Details and Specifications
Generac 48kW Protector Series Automatic Standby Diesel Generator
The Generac 48kW Protector Series diesel generator works with an automatic transfer switch (purchase separately) to provide backup power during a power outage for refrigeration, heating and cooling, pumps and lighting. The Protector offers peace of mind from worries that power outages will leave your home or business without electrical power. Generac guarantees its Protector Series with a five-year limited warranty.
48kW Generac Protector Series Diesel Generators meet local building codes with features and optional accessories designed to make code compliance easy.
The fuel tank is a UL/CUL-142 listed, externally vented and filled double-walled tank with external venting and filling, and leak detection. The double-wall design contains leaks within the outer tank to prevent environmental contamination. A leak-detection feature shuts down the generator and issues an alarm.
Other Code Ready Accessories include an emergency stop and fuel cut off, a fuel spill and recovery system, locking fuel caps, and low-fuel alarms, among other Code Ready Accessories.
The 48 kW Generac Generator RD04833A is powered by an in-line, four-cylinder diesel engine with cast iron cylinder heads and aluminum pistons. The liquid-cooled, 3.3-liter overhead-valve power plant provides efficient and reliable power over a long life span.
Built-in protection from high engine or oil temperature, low oil pressure, and over-crank/over-speed conditions provide engine shutdown to prevent damage and issue alerts for maintenance.
This engine consumes four gallons of diesel per hour at full load and the 62 gallon tank provides a 28=hour run time at half load.
The Evolution Controller manages all aspects of The Protector operation. It continuously monitors the incoming utility supply lines and starts the generator two to 1500 seconds (dealer programmable to prevent starts during momentary outages) after it detects an outage. After startup, it instructs the automatic transfer switch to isolate the building from the utility lines and supply power from the generator.
After the utility restores power, the generator is disconnected and the utility supply is reconnected. The engine runs during a cool-down cycle, then shuts down.
The controller has a two-line, multi-lingual display with a back-lit, membrane keypad that displays generator status at glance with colored LEDs and provides access to the Evolution's reports and alerts, and allows programming of exercise periods and maintenance scheduling.
The Evolution monitors engine sensors, regulates the generator voltage and frequency, and provides extensive fault reporting. Integrated into the controller is a smart battery charger that maintains the battery and alerts the owner to install a new battery in advance of a battery failure.
Protector Series Generators come equipped with Mobile Link Connectivity. Monitor generator status from anywhere with a smartphone, tablet, or PC. Access status and maintenance alerts. Connect with authorized service dealers for fast, proactive service.
Eliminate trips outside to check the display with an optional Basic or Advanced wireless monitor. View generator status with the basic model, or step up and add reports, alerts, and programming functions with the advanced model.
