Product Overview

Samlex 40A 24V Dual Bank Battery Charger

This advanced, fully automatic 40 Amp battery charger is ideal for charging all types of 24 Volt lead-acid batteries (Flooded, AGM, Gel Cell) from either a 120 V, 60 Hz or 230 V, 50 Hz AC source. Featuring a DIP switch setting, it allows conversion to a two-stage algorithm to charge batteries connected to a DC load (DC UPS). The unit can also function as a DC Power Supply and is equipped with overload, short-circuit, and over-temperature protection. It can charge up to 2 separate battery banks simultaneously.

Expert Overview

The Samlex 40A 24V Dual Bank Battery Charger with Temperature Sensor is an advanced, fully automatic charging solution designed for 24-volt lead-acid batteries, including Flooded, AGM, and Gel Cell types. This unit is suitable for IT environments requiring reliable battery maintenance or DC power supply capabilities. It can charge up to two independent battery banks simultaneously, eliminating the need for an external isolator. The charger operates from either a 120 V, 60 Hz or 230 V, 50 Hz AC source, user-configurable via DIP switch. For applications involving batteries connected to a DC load, the SEC-2440UL can be configured for a two-stage charging algorithm, functioning as a DC UPS. It also features overload, short-circuit, and over-temperature protection, along with a temperature sensor to optimize charging based on environmental conditions. Integrated voltmeter and ammeter provide real-time monitoring.
