Sentinel 150 Automatic Battery Chargers

The Sentinel 150 series offers reliable charging for continuous float charge and standby power systems. Using switch mode technology, this automatic battery charger delivers efficient power conversion, reduced heat dissipation, and a compact design. The low output ripple, less than one percent, makes them suitable for sealed and vented batteries, including Nickel Cadmium and Lead Acid.

They are widely used in power generation, telecommunications, and industrial automation. Backup battery systems for generators, electrical infrastructure, and remote communication stations depend on their consistent performance. They also provide steady power for industrial control systems and machinery.

Sentinel 150P Programmable Switch Mode Battery Chargers

The Sentinel 150P programmable series provides a multi-stage charging system that adjusts based on battery condition. It delivers maximum current during charge recovery, then transitions to a float charge mode to maintain optimal voltage. Output remains limited to the rated maximum, even during heavy loads such as engine cranking. This industrial battery charger supports various battery chemistries, including vented lead acid, Calcium-Calcium, sealed VRLA (AGM or Gel), and Nickel Cadmium.

Industries such as transportation, marine, and emergency backup systems rely on the Sentinel 150P for dependable battery maintenance. Fleet vehicles and railway applications benefit from its intelligent charging process, preventing power loss and maximizing battery life. Marine vessels and offshore equipment use it to maintain consistent power levels, while hospitals, security systems, and emergency lighting systems count on their reliability for uninterrupted operation.

Sentinel 300P Programmable Switch Mode Battery Chargers

The Sentinel 300P series is designed for applications that require advanced power control, monitoring, and protection. This industrial battery charger features multi-stage charging, including float, bulk, absorption, and AutoBoost modes, having fast recovery while maintaining long-term battery health. Built for high-efficiency operation, they tolerate wide supply voltage variations and generate minimal heat. The low ripple output makes them safe for sensitive electronics and standby power applications.

This automatic battery charger serves industries such as oil and gas, defense, and utility infrastructure. Remote drilling sites and offshore platforms require dependable battery charging for continuous operation. Military vehicles and installations depend on reliable power management, while substations and grid management systems rely on the Sentinel 300P for backup power.

SMPS Battery Chargers

The SMPS series provides a constant output voltage with current limitation, making them suitable for permanent connection to genset starter batteries. With a rugged metal case and bolt or stud mounting options, this automatic battery charger maintainer withstands demanding environments. Features include short-circuit protection, overload protection, high-temperature safeguards, and a rectifier fail output. The float charging system keeps batteries in optimal condition without overcharging.

This automatic battery charger is widely used in genset and backup power, heavy equipment, and industrial automation. Generator starter batteries require a stable and consistent power source, and heavy machinery depends on reliable charging systems for smooth operation. Automated control systems in industrial environments also benefit from the continuous power support these chargers provide.
