Technical data

Cooling	Convection cooling or forced cooling for units with a rated current greater than 80ADC (standard).
Standard equipment	Current/voltmeter for the GR output, analog Kl.1% (72*72mm); mains isolating transformer according to VDE 0551; mains/battery/grid fuse; control circuit fuses if necessary; "manual charging stage" for charging open battery systems on request
Options	external setpoint setting via resistor or potential-free via computer output; temperature compensation of the charging voltage; adjustment of current and voltage by means of a fine potentiometer on the front of the unit instead of on the controller card (at extra charge); 3-fold switchable voltage level (heavy charging/manual charging); 2-fold switchable current limitation (IU-Ia characteristic)
Power supply	1/N/PE 230V 50Hz +/-10% (others on request at extra charge), cable feed in the standard version from the bottom.
Permissible disturbance variables	mains voltage/ frequency fluctuations +/-10%; load changes 0-100
Perm. ambient temperature	0°C - 40°C, at 80% relative humidity, others at extra charge
Installation altitude	Max. 1000m over NN
Characteristic curve	IU (DIN 41773)
Short circuit resistance	Unrestricted on the basis of the permissible ambient temperature
max. ripple	approx. 5% rms at rated current without connected battery, additional smoothing as special equipment
Voltage constancy	+/- 1%
Power Consistency	+/- 2%
Power failure bridging	20 ms, for use without accumulator set
Radio interference suppression	A (B, against surcharge)
Ordering information	If additional equipment is used, the indicated dimensions may increase. If the cable lengths to the DC consumers require particularly high cable cross-sections, please specify. For factory consideration, please inform us of the intended battery type when ordering.
