1. Introduktion
The Samlex SEC-2440UL is a high-performance, UL-listed 24-volt, 40-amp battery charger. It is engineered for efficient bulk charging of 24V battery systems, including AGM, Gel, or wet cell types, with capacities of 150 amp-hours (Ah) or more. This unit also serves as a reliable floating charger for long-term maintenance of batteries 100 Ah or larger.
Key features include proportional fan cooling for optimal temperature management, a fan mute selection for quiet operation, and temperature compensation to ensure precise charging across varying environmental conditions. The charger offers selectable input voltage (115 VAC or 230 VAC) and can be configured for specific battery chemistries, such as true Gel batteries, or utilized as a stable power supply. Its robust design makes it suitable for diverse applications, including automotive, marine, RV, communications, military, and robotics.

4. Opsætning
4.1 Udpakning og inspektion
Carefully remove the charger from its packaging. Inspect the unit for any signs of damage during transit. If any damage is found, do not operate the charger and contact your supplier immediately.
4.2 Indgang Voltage Valg
The SEC-2440UL supports both 115 VAC and 230 VAC input. Locate the voltage selector switch on the unit (refer to the product diagram if available) and ensure it is set to match your local AC power supply. Incorrect voltagDette valg kan beskadige enheden.
Note: When operating on 115 VAC, the unit requires a dedicated 30 amp kredsløb.
4.3 Valg af batteritype
The charger can be optimized for different battery types (AGM, Gel, Wet). Consult your battery manufacturer's specifications for the recommended charging profile. Refer to the charger's internal settings or external switches (if present) to select the appropriate battery type. This ensures optimal charging and extends battery life.
4.4 Mounting and Ventilation
Mount the charger in a location that allows for adequate airflow around the unit, especially around the cooling fins and fan. Avoid enclosed spaces. Ensure the mounting surface is stable and can support the weight of the charger.
5. Betjeningsvejledning
5.1 Tilslutning til batteriet
- Ensure the charger is disconnected from the AC power supply.
- Connect the positive (+) charger cable (typically red) to the positive (+) terminal of the battery.
- Connect the negative (-) charger cable (typically black) to the negative (-) terminal of the battery.
- Sørg for, at alle forbindelser er sikre og fri for korrosion.
5.2 Tilslutning til vekselstrøm
- Kontroller, at input voltage selector on the charger matches your AC power supply.
- Plug the charger's AC power cord into a grounded electrical outlet.
- The charger will initiate the charging process. Monitor the digital displays for charging status (voltage og nuværende).
5.3 Fan Operation and Mute Function
The internal fan operates proportionally to the charger's temperature and load, ensuring efficient cooling. If desired, the fan mute selection can be activated to silence the fan during periods of low load or when noise reduction is preferred. Refer to the unit's controls for activating this feature.
5.4 Frakobling af opladeren
- First, disconnect the charger from the AC power supply by unplugging the power cord.
- Next, disconnect the negative (-) charger cable from the battery.
- Finally, disconnect the positive (+) charger cable from the battery.
6. Vedligeholdelse
