19-Dec-23
2.3.3 Constant‐voltage power supply
The charger EL11 is equipped with a constant voltage power supply function. All electrical consumers
of the nominal voltage of 24V can be supplied with 28.6VDC and maximum 10A. The electrical functions
of a vehicle can be tested even with dismounted batteries. Deep-discharged battery sets of a voltage
lower than 0.5V can be revitalized. This function can be used as well for battery sets with permanent
consumers (UPS-function).
NOTICE
Electrical consumers with a load of more than 10A bring down the output voltage of the charger EL11.
The device will not be damaged by this kind of operation. It is short circuit stable.
After switching on EL11 both push-buttons (5A and 10A) are blinking. By pressing both sections at least
for 1 second the UPS-function will be started.
The yellow LED "SPANNUNGSVERSORGUNG" = POWER SUPPLY is illuminated.
