Overview

The Hannibal HR-3P-110V is a three-phase 110VDC battery charger and rectifier rated from 10A to 2500A, engineered to provide high-reliability power supply and battery charging for substations and switchgear. It feeds the protection relays, SCADA, control and tripping circuits of electrical substations and, combined with a stand-by battery, guarantees power backup for substations, SCADA and switchgear even during a total AC outage.

Three-phase input and 6-pulse (B6C) or 12-pulse (B12C) thyristor-controlled topologies with DSP control deliver high power with low THDi, while a galvanic isolation transformer holds voltage regulation and output ripple below 1%. Earth leakage monitoring (OPS-02), DC earth fault detection and transducers with 0–10V / 4–20mA outputs (OPS-11) provide complete supervision, and dual DC UPS / dual battery charger arrangements with DC load sharing deliver the redundancy that transmission and distribution networks demand.

Key features

  • Three-phase 110VDC output, 10A to 2500A, for substation and switchgear DC systems.
  • Supplies protection relays, SCADA, control and tripping circuits with constant-current operation under load.
  • 6-pulse (B6C) and 12-pulse (B12C) thyristor-controlled topologies with DSP control and low THDi.
  • Galvanic isolation transformer, voltage regulation < 1% and output ripple < 1%.
  • Earth leakage monitoring (OPS-02) and DC earth fault detection for network protection.
  • Transducers 0–10V / 4–20mA (OPS-11) and dry contact alarm relays for full supervision.
  • Dual DC UPS / dual battery charger with DC load sharing for utility-grade redundancy.
  • RS232 / RS485 Modbus RTU and Modbus / TCP-IP communication.
