Advanced Features:

Controlled Charging: 

Every NCHF Charger has a Microprocessor which accurately controls the charging in three steps.The charging process takes places in accordance with the IUoUo characteristic and charges more rapidly than other processes.

Increase battery Life:

Every NCHF Charger comes with a battery temperature sensor.When connected, charger voltage will automatically decrease with increasing battery temperature. This feature is especially recommended for sealed batteries which otherwise might be overcharged and dry out due to venting.

Battery voltage sense:

In order to compensate for voltage loss due to cable resistance, NCHF chargers are provided with a voltage sense facility so that the battery always receives the correct charge voltage.

Technical Features:

  • Perfect chargers for any type of battery
  • Quality without compromise
  • Universal 90-265V AC input voltage range and also suitable for DC supply (AC-DC and DC-DC operation)
  • Controlled charging
  • To increase battery life: temperature compensation
  • Battery voltage sense

Applications for DC Power Solution:

  • Lead acid battery
  • NiCd battery
