Installation and Operating Manual
StandBy-Charger Pro
Device for recharging and trickle charge a battery from another battery.
Please read this operating and installation manual thoroughly prior to connection and start-up.
The VOTRONIC StandBy-Charger serves for recharging and trickle charge of the starter battery in vehicles with two battery
circuits. A possible connection can be made between the supply or body battery and the starter battery. Only the operation
with two same nominal battery voltages 12V / 12V is permitted. Mixed operation 12V and 24V is not allowed.
Only the operation with two equal rated battery voltages 12 V/12 V is permissible, mixed Operation 12 V
and 24 V is not allowed.
Device mounting
The StandBy-Charger Pro should be installed as close as possible to the battery to be charged and protected from moisture.
The StandBy-Charger Pro can be mounted at the external attachment points of the casing as shown in figure 2
(specifications in mm).
Input 12...15 V max. 12 A, Output 12,5...14,5 V max. 8 A

- Page 2 To activate the StandBy-Charger Pro permanently, a jumper can be connected from IN+ to EN. Alternatively a switchable 12 V control signal can be applied to the EN terminal for turning the StandBy-Charger Pro on and off. If the StandBy-Charger Pro should be deactivated while the output battery is being charged by the alternator, the D+ signal of the alternator can optionally be connected to the DIS terminal.
- Page 3 Afterwards, connect the output battery to the device. If the StandBy-Charger Pro is activated via the terminal EN and is not switched off by the terminal DIS, the charging of the output battery starts automatically if required.
