The REDARTI Battery Rectifier System is an uninterruptible DC power (DC UPS) system for DC control and protection supply in electricity distribution, substations and power plants, and for DC auxiliary supply and battery charging in energy, automation, telecom and security systems. Besides the most widely used nominal voltages of 24 VDC and 110 VDC, it is manufactured at other nominal voltages from 12 VDC to 220 VDC.
REDARTI Industrial Battery-Rectifier Systems (DC UPS) are top-level power electronics systems developed to supply, with 100% reliability, the uninterruptible DC control, protection and supply power of hydroelectric (HPP), thermal, wind, solar and combined-cycle gas power plants, electricity distribution substations, high-voltage transmission facilities, petrochemical plants, railway signalling centres, ports, the defence industry and critical industrial facilities.
To fully meet your project's technical specifications, harsh operating conditions (extreme temperature, humidity, dust, corrosion) and budget expectations, REDARTI manufactures in two different power electronics architectures: the transformer-based thyristor-controlled (SCR / Thyristor) Heavy Industry Series and the High-Frequency Switch-Mode (HF / IGBT) Modular Series. Our systems are custom-built over a wide voltage range from 12 VDC to 220 VDC and at high capacities from 3 A to 1,000 A.
With our new-generation RedMax v2.07 digital driver platform and its 4x20-character LCD user interface, "Output Current (System Load Current)" and "Battery Current (Battery Charging Current)" can be set independently on two separate channels with milliampere precision. This critical architecture supplies the connected industrial loads (motors, relays, automation panels) at full capacity while reliably preventing the battery from being damaged by overcharge current. By eliminating the risks of battery heating, gassing and thermal runaway, the battery operates within the manufacturer's specified C/10 or C/20 safe charging limits and its service life is maximised.
Our advanced control structure offers Boost/Equalize charging, Float charging and Power Supply (laboratory/industrial DC power supply) modes, and provides the isolated RS-485 Modbus RTU (Holding & Input Registers) communication protocol as standard for industrial automation integration. During mains outages the system supplies the loads from the stationary battery bank with zero transfer time (0 ms), prevents deep discharge of the batteries with "Deep Discharge Protection" (DDK voltage) and automatically restarts charging when mains power returns thanks to its "Auto-Start" function.
Key Features
- Dual Power Electronics Architecture: Heavy-duty, isolated transformer-based thyristor-controlled (SCR) architecture or High-Frequency Switch-Mode (HF/IGBT) modular power stage options.
- Independent Battery Charging Current and Load Current Setting (RedMax v2.07 Software Feature): Setting the system load current (output current) and the battery charging current completely independently prevents damage from over-current, maximises battery life and ensures safe charging regardless of load fluctuations.
- Wide Production Range (12 VDC - 220 VDC / 3 A - 1,000 A): Manufacturing to custom specifications at 12V, 24V, 36V, 48V, 72V, 80V, 96V, 110V and 220V DC nominal voltages and from 3 A up to 1,000 A.
- Multiple Operating Modes (Boost-Float, Manual Charging, Power Supply): In addition to standard battery charging modes, a precise DC power supply mode with adjustable ramp and dwell times.
- Industrial RS-485 Modbus RTU Communication: Remote current/voltage setting, run/stop commands and detailed telemetry/fault monitoring via Holding and Input Registers.
- Uninterruptible DC UPS with 0 ms Transfer Time: Stable, regulated DC power transfer from the battery bank to the loads during mains outages without even a millisecond of interruption.
- DDK (Deep Discharge Protection) Voltage & Automatic Start: Logic that disconnects the load to protect the battery when its voltage falls to the DDK level and restarts automatically ("Auto-Start") when mains power returns.
- Advanced Reporting & Lifetime/Operating Counters: A Reports screen that stores the details of the last run (initial voltage, final voltage, final current, final Ah, elapsed time, exit code), plus Actual Ah (ASa), Total Ah (TAsa), Uptime (UpTi), lifetime and CPU load indicators.
