Programmable universal battery charger with high-frequency IGBT hybrid technology, from a single cell to 600 V DC packs
Forming, conditioning, testing and desulphating batteries of any technology and voltage with a single unit calls for a programmable universal charger with a filtered output current and configurable charging curves. The MMF charges from a single cell up to 600 V DC at 50 to 500 A, runs on single-phase 220-240 V AC or three-phase 220 to 600 V AC, with efficiency above 90 % and power factor above 0.90 averaged over the charge cycle, and lets the user add custom curves to the factory-programmed ones.

The most advanced technology for battery formation, conditioning, test and desulphation.
The MMF is a universal battery charger, digitally controlled and programmable.
It can operate with batteries of any type, from individual cells to complete packs, and it can be programmed to support applications of any type (Formation, Conditioning, Recovery, Desulphation and Regeneration).
It is based on a new hybrid power conversion technology, featuring an unprecedented combination of very high efficiency, unity power factor (PFC), universal capabilities and precise charge control.
The new generation of Universal Chargers
- IGBT-HF Hybrid Converter
- From 50 to 500 Amps
- DC output from 12 to 700 VDC
The two parts that are combined together to compose this "Hybrid" system are:
- Special isolation transformer, with line frequency multiplication system;
- High frequency switchmode converter, based on IGBT technology.
The MMF features a very complete set of charging curves, and the user can complete it by programming new ones, following a very simple procedure.
Thanks to the ultra-filtered output current, this charger ensures a minimal temperature rise in the battery during the recharge process. Moreover, the MMF is suitable to charge battery types that require perfectly constant current and virtually zero ripple.
The MMF is equipped with alphanumeric display & keyboard, Charge History Logger, Programmable Real-Time Clock and Calendar, Audible Alarm and Connectivity package, compatible with wireless Battery Identification Modules and the WEB based Fleet Management System DoctorFleet.com.

WRONG BATTERY AND REVERSE POLARITY | If the battery voltage is outside the acceptable limits, or the polarity is reversed, the charger remains in stand-by mode and gives error/warning message. |
ELECTRONIC OVERLOAD PROTECTION | Complete protection in case of output short circuit or overload. |
ANTI-ARCING | WITHOUT AUXILIARY WIRES: When the battery is connected, no arcing is generated at the connectors. If the battery is disconnected while it's being charged, arcing is possible, so it's necessary to turn off the charger before to disconnect the battery. WITH AUXILIARY WIRES (RECOMMENDED): Full Anti-arcing protection in case of battery disconnection, even while the charge is in progress. |
POWER-ON SELF-TEST | Every time the unit is powered, an automatic self-test of the power electronics and the control boards is executed in less than 10 seconds. In case of fault, the unit remains in safe stand-by mode and gives fault messages. |
AUTOMATIC SHUTDOWN ON BATTERY DISCONNECTION | If the battery is disconnected while the charge is in progress, the charger turns-off automatically within 3 seconds and a specific message is saved in the Charge History Log. |
SAFETY TIMER | An independent safety timer turns the charger off in case of malfunction of the main control unit. |

Frequently asked questions
Which charger can form and desulphate batteries of different voltages and technologies?
A programmable universal one. The MMF charges from a single cell up to 600 V DC at 50 to 500 A, comes with factory charging curves and accepts custom ones, so a single unit covers formation, conditioning, recovery, desulphation and testing of lead-acid and lithium batteries.
How does it protect against connection errors?
If the battery voltage is outside the limits or the polarity is reversed, the MMF stays in stand-by and shows an error message; if the battery is disconnected during charging, it switches off within 3 s and records the event in the charge history log, and with auxiliary wires the anti-arcing protection is complete.
