Overview

The Hannibal HR-1P-24V is a single-phase 24VDC industrial rectifier and battery charger engineered to deliver clean, regulated DC power supply from 10A to 500A. Built on a thyristor-controlled rectifier platform with DSP control, it converts a single-phase AC input into a stable 24V DC output while simultaneously float charging the standby battery, protecting low-voltage control, signalling and instrumentation loads from the damaging effects of mains interruptions.

Designed for high reliability and a long system lifetime, the HR-1P-24V uses a galvanic isolation transformer (B6C / 6-pulse topology) to guarantee full input-to-output separation, low output ripple and precise voltage regulation below 1%. Automatic float, equalize and boost charge modes, adjustable current limiting and soft start make it a dependable 24V DC backup and uninterrupted DC supply for industrial automation, telecom and utility auxiliary systems. Front-panel measured-value display, LED indicators, an audible alarm and dry contact alarm relays give operators full visibility and simple maintenance.

Key features

  • Single-phase 24VDC output, nominal current configurable from 10A to 500A as a voltage or current source.
  • Thyristor-controlled (B6C / 6-pulse) rectifier bridge with fast DSP control for tight voltage regulation < 1%.
  • Galvanic isolation transformer for full input/output separation and ripple suppression (output ripple < 1%).
  • Automatic and manual charge modes: float, equalize and boost charging with programmable boost duration and charge timing control.
  • Adjustable current limiting, soft start, short-circuit protection and over-temperature protection for safe operation.
  • Front-panel interface with LCD display, keypad menu navigation, measured-values display, LED indicators and audible alarm.
  • RS232 / RS485 communication with Modbus protocol (RTU) and dry contact alarm relays for remote monitoring and control.
  • Operation continues while mains fail; automatic startup and restart after fault for low-maintenance service.
