What this product is

What this product is

This controller occupies the central slot of Emerson telecom power subracks, auditing AC inputs, DC bus parameters, and battery bank health while regulating rectifier float levels and contactor states.

What problem it solves

Solves lack of synchronized voltage regulation, prevents battery failure from undercharging or thermal runaway, and bridges field power plant telemetry to remote operations teams.

Who and where it is for

Engineered for Emerson NetSure embedded subracks, 4G/5G indoor telecom power plants, and industrial utility substation DC monitoring retrofits.

Core advantages

  • Industrial-Grade Hardware Architecture: Embedded processor engineered for high electromagnetic noise tolerance ensures non-stop uptime.
  • Advanced 4-Stage Battery Care: Integrates constant-current bulk, float, equalize, and thermal compensation charging to maximize battery lifespan.
  • Comprehensive Audio/Visual & Relay Alarms: Onboard status LEDs, audible buzzer, and programmable dry contacts facilitate site telemetry integration.
  • Field-Friendly Operation: Backlit LCD interface and intuitive keypad allow technicians to audit telemetry and adjust parameters without a laptop.
