Bộ sạc ắc quy 12 VDC cho PS150 Campbell Scientific 29290

Overview

The 29290 is a 12 Vdc power supply that includes a charging regulator. Charging power for the 29290 is typically supplied by an unregulated solar panel, AC/AC transformer, or AC/DC converter. The 29290 provides charging with temperature compensation for optimal charging and battery life. A maximum power point tracking algorithm is incorporated for solar inputs to maximize available solar charging resources.

Benefits and Features

  • Protects against high-amperage and high-voltage damage to power supply

  • Battery reversal protection

  • Allows simultaneous connection of two charging sources (e.g., solar panel, ac wall charger)

  • ETL listed Class 2 power supply

Detailed Description

The 29290 is a micro-controller-based smart charger with temperature compensation that optimizes battery charging and increases the battery's life. Two input terminals enable simultaneous connection of two charging sources. They also incorporate a maximum power point tracking algorithm for solar inputs that maximizes available solar charging resources.

The 29290 has several safety features intended to protect the charging source, battery, charger, and load devices. Battery-reversal protection is included, as well as ESD and surge protection on all of the 29290 inputs and outputs.
