The upgrade kit can be installed during a Preventive Maintenance (PM) visit, or scheduled as a stand-alone service trip. In either case, we think you’ll agree these upgrades are an economical solution and will improve system performance and reliability.

BATTERY CHARGER VOLTAGE CONTROL BOARD UPGRADE

SCI’s new Battery Charger voltage control board upgrade offers two distinct advantages over the boards originally supplied with our legacy products.

• A greater degree of protection against high voltage conditions: By using two ‘comparator’ circuits, the new boards utilize two distinct levels of detection to protect the DC load(s) from an over-voltage situation. The first level will cause the voltage to phase back approx. 10%. However, if the output should continue to rise, a second detector will actually cause the charger to shutdown and protect the load.
• Improved Current Limit: Controls current to the battery more precisely through sensor in series with the battery bank.
• Eliminates “Drift”: Eliminates the need for maintenance personnel to frequently adjust the output voltage due to the changes in the gain of the gate drive circuitry.

OSCILLATOR/SYNCHRONIZATION (SYNC) BOARD UPGRADE

This upgrade will appeal to any client who has experienced off-frequency conditions and random out-of-sync alarms.

• Utilizes advanced frequency control for the oscillator
• Includes phase lock-loop technology for synchronization
• A complete ‘form, fit and function’ replacement. The new boards physically fit into the existing board locations
• Eliminates nuisance, random “out-of-sync” alarms
• Eliminates the need for service and maintenance personnel to make frequent adjustments to the sync circuitry

STATIC SWITCH CREST FACTOR BOARD

• Improves performance with non-linear loads such as switch mode power supplies
• High Crest Factor loads generated by switch-mode power supplies can be handled without oversizing the inverter
• SCI’s Crest Factor circuit has the ability to recognize true overloads and faults, thereby eliminating nuisance transfers and “bouncing” of the load between the inverter and the alternate source
• Compatible with today’s highly sensitive electronic loads
• Ease of adjustability using a dip switch that supports settings of 100, 120, 130 and 150% of rated load
• Upgrade kit also includes an Auto-Retransfer circuit with standard 30 second timer

REMOTE THREE (3) POSITION MANUAL MAINTENANCE BYPASS SWITCH (RMBS)

• Adds flexibility and safety to a UPS/Inverter installation
• Offers complete isolation of your inverter/UPS, which enables maintenance personnel as well as SCI Technicians to completely remove all power sources from the unit, allowing them to work on the unit safely, while maintaining power to your load.
  
  Housed in a wall-mounted , NEMA 1 enclosure A virtually selfcontained product, including its own sync logic circuitry.
  
  Can be mounted in a room separate from the UPS/inverter

BATTERY MONITOR/POWER ANALYZER

• Provides the 3-Ps of battery monitoring:
• Proactive
• Continuously monitors and analyzes the condition of your station battery
• Connectivity for remote monitoring
• Predictive
• Trends the battery’s condition over time; compares the battery’s performance to a known baseline standard
• Virtual cell software model utilizes a “Performance Index” to accurately calculate the expected remaining battery capacity
• Preventive
• Provides capability for AMETEK SCI to monitor batteries remotely and issue reports, etc. based on real-time analysis so you can take care of the battery before problems occur
• Improved maintenance, data collection, and safety
