SB7 Battery Charger

SB7 Industrial Battery Charger

 

The SB7 is RIC Electronics’ premier SCR battery charger. The SB7 provides power to critical DC loads through a wide range of outputs and is engineered for maximum reliability and ease of maintenance.

 

A key component of the charger is usability, that’s why RIC has designed a responsive human-machine interface with built in LEDs and mimic screen. Providing a bright two line vacuum florescent display and central keypad, performing routine maintenance couldn’t be easier.

 

RIC Electronics focuses on continual innovation. This has enabled the SB7 to provide “Mean Time Between Failure” to over 200,000 hours and reduce “Mean Time To Repair” to less than 30 minutes.

 

Offering fast lead times and customized solutions, RIC Electronics is your go-to for all industry applications.

Types of Batteries

 

The SB7 standby battery charger can use valve-regulated lead-acid batteries (VRLA) – sealed or flooded, or nickel cadmium batteries (NiCd). Depending on the requirements of the job, the batteries chosen will have either a 10 or 20 year design life. Based on specification, batteries can be integrated into the SB7 unit, put in an external enclosed battery rack, or put in an external open battery bank. RIC will provide the entire solution.
