Stationary	Stationary Load Bank Applications
	Manual Generator exercise and testing via local or remote manual control Minimum loading of generators	Automatic Generator exercise, control from remote control contacts Automatic exercise/test via programmable microprocessor control Automatic load leveling/load regulation to maintain preset load on generator by sensing of total load and automatic addition or subtraction of Load Bank component Reverse power/regenerative power protection of generator by sensing power direction and magnitude and automatic addition of Load Bank component to act as a power sink	NFPA Testing Simplex Stationary Load Banks can be used to satisfy the requirements of the National Fire Protection Association (NFPA) for emergency stand-by power systems. These requirements concern acceptance testing and periodic on-site testing and maintenance of emergency and stand-by power systems. The essence of the requirements is that emergency and stand-by power systems are to be tested under load.

	Stationary Load Bank General Specifications
	Ambient Temperature Max. Air Intake Temp.: 120°F Air Temp. Rise: Temp. Rise (°F) = KW x 3000 CFM Note: Air temperatures at plane of exhaust can vary greatly from point to point. Contact Simplex for temperature gradient date and maximum exhaust air temperatures for specific Load Bank. Altitude Above 3500', contact Simplex Enclosures Standard: NEMA-3R, outdoor weatherproof Optional: NEMA-1, indoor Connection Copper plated bus bar terminals Control/Fan Power Source Standard design—derived internally, from load bus. Cooling fan operates at line voltage. Control circuits operate 120V, either from transformer power supply of from 120V line-neutral connection. As an option, the Load Bank can be designed to obtain control/fan power from an external source, supplied by user. Voltage and Load Steps Integral load steps are the basic branch circuits of the Load Bank. The Load Bank is designed in building block multiples of the integral load step. Each integral load step represents a discrete load circuit with branch circuit fuse protection. Integral load steps are “course:” relatively large in value. To obtain “fine” load step resolution, add fractional load steps. If multiples of the integral load step do not equal the total capacity desired, add fractional load steps to fill-in the difference. Simplex Load Banks can be used to satisfy the requirements of the National Fire Protection Association (NFPA) for emergency stand-by power systems.	MODEL LOAD CAPACITY AIRFLOW REQUIREMENTS APPROX.
