Description

Functional description
The chargers of the G22-300 series are designed in the primary switch mode technology. A constant DC voltage with low AC voltage component during the charging process ensures a maximum lifetime of maintenance-free lead batteries. As a standard, the charging of the battery follows an IUoU curve, 2nd stage charging with 10-hour timer. Furthermore, an IUIa characteristic for batteries and maintenance-free batteries can be selected by a switch.

Three built-in LEDs then indicate the following states:
  • Yellow LED: charging current is flowing (LED), battery charged by 90% (LED flashes)
  • Green LED: battery full charge
  • Red LED: reverse polarity (LED), exceeding the charging time and over temperature (LED flashes)
Mechanical design
All components are mounted on the PCB. The PCB is in a case made of plastic sides with cover plates, which are screwed against each other, and has aluminum front and back sides. Type 24 V 12 A has a temperature-controlled cooling fan built-in.

The mains connection is made by a permanently mounted plug. The devices comply with protection class I.

CE marking
The devices meet the basic requirements of the law relating to electromagnetic compatibility (89/336/EEC EEC treaty) and the low voltage directive (73/23/EEC).

Features

  • Current limiting, overvoltage protection (optional)
  • short circuit, reverse polarity protection
  • Reverse polarity display, charging indicator
  • light weight, small dimensions
  • charging of deeply discharged batteries
  • three adjustable characteristics
  • derating at high temperature
  • Start a new charge cycle after power reset or reconnecting a new battery
