SLC Pure Plus: Sigma Lambda Controller Pure Plus (Succeeded by SLC Pure Plus 2)
 

SLC Pure Plus is a complete Plug and Play Lambda Controller capable of 0.01 Lambda accuracy without the need for constant and complicated "free air calibration".
 
The SLC series Lambda Controllers are the only Lambda Controllers on the market utilizing programmable switch capacitor and programmable logic technology. Such advanced technologies allow for high accuracy and fast response times in an efficient integrated design.
Key Features
  • 0.01 Lambda accuracy
  • Digital display
  • USB connectivity
  • RPM Pickup
  • Single 0-5v analog input
  • Real-time datalogging
  • Programmable Linear Output
  • Programmable Narrowband Output
  • Over voltage protected
  • Dual fuse design
  • 2x-4x the warranty of competing units
  • Widest operating temperature of any competing unit

Plug and Play with Free Air calibration
 
SLC Pure Plus is a true Plug and Play solution, just connect power and ground and you can immediately analyze the Lamba/AFR of your exhaust gases. Out of the box, SLC Pure Plus is able to achieve 0.01 lambda accuracy without Free Air Calibration.
 
Although Free Air Calibration is not required, it is a feature that is offered for those who want increased accuracy. Furthermore, Free air calibration is required only half as often as the Innovate Lambda Controllers.
 

Quality and Reliability 
 
SLC Pure Plus is designed to be more reliable than competing units. SLC Pure Plus is the only unit on the market featuring dual fuses; one fuse to protect the electronics, another fuse to protect the sensor. Competing units do not even feature a single fuse making them unsuitable for an automotive environment.
 
For each and every component, SLC Pure Plus uses only the highest temperature rated version of that component, our competitors use only the lowest priced version of components which results in an operating temperature range that is suitable for use only on a lab bench.
 
SLC Pure Plus feature tantalum power filtration capacitors with a rated life of 500k hours @ 125C, all other capacitors are X7R rated ceramic capacitors. Our competitors use short life Electrolytic, short life tantalum, and lower than X7R rated ceramic capacitors.
 
Each and every input and output on SLC Pure Plus feature current limiting and over voltage protection.
 
Better design and higher quality components allows us to offer a base warranty that is 2x to 4x that of our nearest competitor. With the extra 6 month bonus warranty as part of our "Give 10" promotion, our warranty is 3x to 6x that of our nearest competitor.
