DSE9120 (Obsolete)
12 Volt Switch Mode Battery Charger
The DSE9120 is a 7.3 Amp battery charger suitable for 12 Volt lead-acid batteries.

The charger has been designed to be permanently connected to automotive batteries, keeping them charged to their maximum capacity. The chargers can also be used to supply a standing load that is attached to a battery. To improve reliability the chargers do not include any moving parts. The technology inside the chargers has been designed to avoid overcharging and overloading. The chargers will also continue to operate during cranking and running and have the ability to accept multiple AC voltage connections.

Further Information

Main Features	Lightweight Compact design Can remain operational during engine cranking and running Suitable for connection to a wide range of AC voltages between 100V and 240V, 50Hz or 60Hz. No moving parts Switch mode design Overload & short circuit protection LED charging indicator Convection cooling Minimum 80% efficiency throughout full operating range
Operation	The charger has been designed to supply current to a battery until the battery terminal voltage is equal to the set float voltage. After this it will change to a trickle charge current. When the battery voltage falls, due to a load being applied and the battery being discharged, the charger will supply current to restore the voltage of the battery to the float voltage.
Important Notes	This product is now obsolete. See 9130 for the new alternative.
