dse9120-9240

Product catalog summary

Specification
The DSE9120 and DSE9240 are battery chargers designed for 12V and 24V lead-acid batteries, respectively. The DSE9120 provides 7.3 Amps, while the DSE9240 provides 3.5 Amps. Both are intended for permanent connection to automotive batteries, ensuring they remain fully charged and can also support a standing load. The chargers are designed without moving parts to enhance reliability and prevent overcharging and overloading. They can operate during engine cranking and running and accept multiple AC voltage connections.

Features

Lightweight and compact design
Operational during engine cranking and running
Compatible with AC voltages from 100V to 240V, 50Hz or 60Hz
No moving parts
Switch mode design
Overload and short circuit protection
LED charging indicator
Convection cooling
Minimum 80% efficiency across the full operating range

Operation
The charger supplies current until the battery reaches the set float voltage, then switches to trickle charge. If the battery voltage drops due to discharge, the charger restores it to the float voltage.

Compliance
Standards include EN55022 Class B, EN61000-3-2, EN61000-3-3, EN50081-1, and EN50082-1.

The DSE9240 is a 3.5 Amp battery charger suitable for 24 Volt lead-acid batteries. Both chargers are 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. 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.
