Campbell Scientific offers two new ETL listed Class 2 power supplies, the PS150 and CH150, for recharging 12 Vdc, valve-regulated, lead-acid (VRLA) batteries. The PS150 contains a 12 Vdc, 7 Ah rechargeable battery, whereas the CH150 is for applications where the user provides the battery, such as our BP12 or BP24.
The PS150 and CH150 are microcontroller-based smart chargers that incorporate many of the attributes provided in the PS200 and CH200, but do not have the onboard measurement capabilities of the PS200 and CH200. These attributes include temperature compensation to optimize battery charging and increase the battery's life. Two input terminals enable simultaneous connection of two charging sources.
For solar inputs, a maximum-power-point tracking algorithm maximizes available solar charging resources. Safety features such as battery-reversal, electostatic discharge (ESD), and surge protection help safeguard the charging source, battery, charger, and load devices.
