Our Type GMC-E (modular controller-regulated expanded-function rectifier) battery chargers are suitable for charging of lead-acid accumulators of 9, 12, 15, 18 or 30 cells. The various appliance types can thus be used to charge lead-acid batteries of rated voltages of 18V, 24V, 30V, 36V and 60V.
The charger-rectifier was originally developed for charging of equipment-building batteries for level-crossing control systems. Appliances of this type are nowadays also used in other applications, such as for actuation of platform-screening doors and charging of signal-cabin batteries. These units are extremely robust and can be operated within an expanded temperature range of -25ºC to +70ºC.
The battery chargers are designed for connection to a 230 VAC mains supply with a tolerance of +/- 10 % and a frequency of 50 or 60 Hz. The input-side (mains-side) fusing system must be designed for a max. 5.2 A current. The following appliance types are available (max. output current also stated):
- GMC-E 18V / 36A
- GMC-E 36V / 18A
- GMC-E 30V / 20A
- GMC-E 24V / 27A
- GMC-E 60V / 10A
Our battery chargers ensure, in conjunction with the buffer batteries, that power supply is maintained with certainty for a defined period in case of a mains power failure. The charge state of the batteries is therefore continuously monitored by the appliances.
