Universal battery charger Amperis MHF

Universal battery charger Amperis MHF

Multi-Voltage, Multi-Capacity, Multi-Chemistry.

The MHF is a revolutionary traction battery charger, designed for conventional, opportunity and rapid charging applications.

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.

This system offers very high electrical efficiency, near unity power factor and very low output current ripple, moreover it features a real universal charging capability: multivoltage, multi-current, multi-application.

The most advanced chargers, based on a IGBT Hybrid technology

  • THE MOST ADVANCED TECHNOLOGY,
  • MAXIMIZES BATTERY LIFE AND PERFORMANCE,
  • REDUCE ENERGY USE AND CARBON EMISSION.
  • From 60 to 600 Amps
  • AC input from 200 to 600 VAC
  • DC output from 12 to 400 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 charging curve is programmable for any battery type, including Lithium technologies.

When used with Lead-Acid batteries, the ultra-filtered output current and the unique control algorithm ensure a perfect mixing of the electrolyte (without using air-pumps), while reducing the water consumption and the temperature rise of the battery, as well as the energy consumption.

The MHF is controlled by the new digital board Amperis, 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.

With the control board G-01, the programmable features of these chargers are almost infinite.

PROTECTION

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.
