Campbell Scientific PS150 – 12 V Power Supply with Charging Regulator and 7 Ah Sealed Rechargeable Battery

Name: Campbell Scientific PS150 - 12 V Power Supply with Charging Regulator and 7 Ah Sealed Rechargeable Battery
SKU: PS150
Price: 470.58 USD
Availability: InStock

Overview

The PS150 is a 12 Vdc power supply that includes a rechargeable 7 Ah valve-regulated lead-acid (VRLA) battery and charging regulator. Charging power for the PS150 is typically supplied by an unregulated solar panel, AC/AC transformer, or AC/DC converter. The PS150 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.

The PS150 is ETL certified. The ETL Mark is proof of product compliance to North American safety standards.

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 PS150 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 PS150 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 PS150 inputs and outputs.

The PS150 replaced the PS100.

Specifications

Operational Temperature	-40° to +60°C (VRLA battery manufacturers state that “heat kills batteries” and recommend operating batteries at ≤ 50°C.)
Dimensions	19.3 x 7.6 x 10.6 cm (7.5 x 3 x 4.2 in.)

CHARGE – CHARGE Terminals (AC or DC Source)
AC	18 to 24 VRMS (internally limited to 1.2 ARMS)
DC	16 to 40 Vdc (internally limited to 0.85 Adc)

SOLAR Terminals (Solar Panel or Other DC Source)
-NOTE-	Battery voltages below 8.7 V may result in < 3.0 A current limit because of fold-back current limit.
Input Voltage Range	15 to 40 Vdc
Maximum Charging Current	4.0 Adc typical (3.2 to 4.9 Adc depending upon individual charger)

Quiescent Current
No Charge Source Present	160 μA at 13.7 Vdc
No Battery Connected	930 μA at 30 V input voltage (ac or dc)

Battery Charging
-NOTE-	The “T” represents temperature in degrees Celsius.
FLOAT Charging	Vbatt(T) = 13.65 V – (24 mV) x (T – 25) + (0.24 mV) x (T – 25)²
Accuracy	±1% (on charging voltage over -40° to +60°C)
