The Hannibal HR Series is a complete family of industrial rectifiers and battery chargers that convert alternating current (AC) into clean, regulated direct current (DC) for the most demanding industrial applications. Built on a thyristor-controlled rectifier platform with fast DSP control and a galvanic isolation transformer, every HR Series unit delivers a reliable DC power supply while keeping a stand-by battery charged — protecting critical loads from the damaging effects of power interruptions and providing a true backup and uninterrupted DC supply.
Single-phase models (HR-1P) cover 10A to 500A and three-phase models (HR-3P) extend from 10A up to 2500A, with nominal outputs of 24VDC, 48VDC, 110VDC, 125VDC, 220–240VDC and 400VDC. Across the range, voltage regulation and output ripple are held below 1%, automatic float, equalize and boost charge modes maximise battery life, and B2C / B6C / B12C (2-, 6- and 12-pulse) topologies — plus an IGBT option — let users tune total harmonic distortion (THDi) and power factor for each site.
Designed for high reliability and a long system lifetime of 20+ years, HR Series chargers operate in harsh environments and high ambient temperatures, support a wide range of maintenance-free and vented batteries (OPzS, OPzV, VRLA, Ni-Cd, Li-Ion, Calcium-Ion, Sodium-Ion, Gel, AGM, lead-acid and valve-regulated types from brands such as EnerSys and Exide), and offer comprehensive monitoring through RS232 / RS485 Modbus communication, dry contact alarm relays and a front-panel LCD display.

Across the HR range
Common technical platform
All HR Series rectifier-chargers share a microprocessor-based DSP control platform that offers exceptional output stability and adaptability. Features common across the range include a galvanic isolation transformer, thyristor or IGBT power conversion, float / boost / equalize charging, adjustable current limiting, voltage regulation < 1%, output ripple < 1%, ripple suppression, soft start, and operation as either a voltage source or a current source with constant-current operation under load.
Input AC voltage options cover 110V to 440V in single-phase (1P) and three-phase (3P) configurations at 50 or 60 Hz, with an input voltage tolerance of +15% / -10% and frequency tolerance of ±10%. Nominal power factor is typically 0.75 / 0.80 (1P / 3P) and can reach 0.9 to 0.99 with the appropriate front end. The range supports dual DC UPS / dual battery charger and DC load sharing configurations, and can be supplied as AC-DC converter or DC-DC converter solutions, including the front end of double-conversion AC UPS systems up to 500 kVA.
