GFS4x180V30A (GFS) is microprocessor device for charging and formation of all types lead-acid batteries (all nominal capacities and technologies) nominal voltage 12V connected in a row up to 10 batteries. It is developed as a consequence of need for small, easy for use, safe, reliable device for servicing, recharging and formation of starter and traction (industrial) and stationary batteries. It consists of energy cabinet with control unit and 4 charging modules GCM180V30A. Control unit has LCD display and keyboard for each charging module. Charging module is three-phase high frequency half-bridge constant voltage charger with current limit. That means that current reaches output voltage on connected battery, which is limited. After reaching desired voltage, that voltage level is maintaining constant and charge current drops as battery is charging. Charge current (current limit) is selected as function of nominal battery capacity. Also, charging voltage is settable for different battery technologies. Voltage, current, duration and capacity are controlled and many precaution measures are implemented.
As device is microprocessor, with measuring current, voltage, duration, Ah, temperature of heat sink of semiconductor parts and power transformer, it is possible to implement different algorithms. It is possible to change voltage and current limits, conditioning of charge characteristic, pausing, waiting for event (measuring Ah during charge), conditioning end of charging (duration, Ah...) etc.
Energy circuit is made of input filter with high quality electrolytic capacitors (EPCOS-SIEMENS 105C), high-frequency transformer (ETD Siemens) and mosfet half-bridge (International Rectifier IR), ultra fast diodes, inductance and PWM modulator. Working frequency is 50 kHz.  
Thanks to voltage limit, it is possible to charge without surveillance, because there is not over charge (over night or during weekend). As well, in a case of main power failure during charge, after it’s returning device automatically continues charging with parameters, which were previously set (before power failure). In control unit there are 4 LCD displays with 2x16 characters, shows values of current, voltage, time, capacity, device status, warnings, alarms etc (option). There are more than 10 menus for setting the parameters of charging (option). Start (scroll) and stop (select) buttons, switch R/S (Ready/Set) and LCD display for indication are placed on the devices front panel. Energy cabinet has all necessary installation for 4 charging modules, main swich, input AC fuse 3x40A, output DC fuses C32A and connectors for AC supply cable and output DC cables.
Gaus Charging Module GCM180V30A has following protections:
1.    no sparks during connecting or disconnecting plugs from battery in charge operation;
2.    forced temperature controlled air cooling;
3.    control of a minimum of allowed connected battery voltage (forbidden start for voltages less than 1V);
4.    temperature protection on heat-sink of semiconductor energy components;
5.    in case of main power failure, after its restoring, charging automatically continues with earlier set parameters;
6.    slow fuse 3x25A C in AC circuit;
7.    slow fuse 32A in DC circuit;
8.    soft start of PWM modulator;
9.    soft start in charging input electrolytic capacitance;
10.    short circuit protection (if detected current is more than 35A charger is automatically turned off);
11.    over voltage protection;
12.    protection from plugs (cables) falling during charge (freezing device until solving of problem);
13.    Reverse polarity protection with forbidden start.
