Sentry Models

Made in USA, 10+ models cover all Telecom, UPS and utility DC applications, for any scale. UL certified and CE marking.

All models (except NB4/8) have a 4-pin port for HMI for service/calibration or permanent onsite display.
Centralized dashboard Master-800 can manage hundreds of remote units efficiently.
Legacy software Battery Analyzer PC software is supplied and compatible with all models.
NERC Auto-fill Excel software is available for customizing battery service reporting for NERC compliance.
MyBattery Platform™ and Geo-map reporting are recommended for large scale Telecom/Utility applications.

SOH/SOC/Runtime algorithm has been implemented to all Telecom 24V/48V models.
