Orderable12 V Charging Regulator
Overview
The CH150 is a charging regulator for an external rechargeable 12 V VRLA (valve-regulated lead-acid) battery, such as the BP12 or BP24 offered by Campbell Scientific. Charging power for the CH150 is typically supplied by an unregulated solar panel, AC/AC transformer, or AC/DC converter. The CH150 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 CH150 is ETL certified. The ETL Mark is proof of product compliance to North American safety standards.
Key Advantages
Technical Description
The CH150 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 CH150 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 CH150 inputs and outputs.
The CH150 replaced the CH100.

Common Accessories
(9)A100
Null Modem Adapter for Rechargeable Power Supplies
The A100 adapter attaches to the CH150 to provide a null modem connection. This functionality is required in a station where a datalogger will not be present, such as a phone-to-RF base station.
Please note that only one A100 or A105 can be used at a time.OrderableA105
12 V Terminal Expansion Adapter for PS1X0/200 or CH1X0/200
An A105 adapter connected to the CH150 provides four additional 12 V terminals and four additional ground terminals. The extra terminals may make it easier for the customer to wire multiple continuously powered 12 Vdc devices to the power supply.
Please note that only one A100 or A105 can be used at a time.Orderable34040
10 A External Battery Cable for CH150, CH200, CH201, PS150, or PS200
The 34040 connects a CH150 power supply to an auxiliary, 12 V flooded battery such as a deep-cycle marine or RV battery. This is helpful when the battery is not in the same enclosure as the charge regulator/controller. The cable length is 3.048 m (10 ft). This two-conductor cable has a two-pin connector on one end that attaches to the power supply, and pigtails on the other end that attach to the battery.
Orderable34031
BP12 and BP24 10 A Battery Cable
This 24 in. battery cable comes attached to the BP12 and BP24 batteries. One end terminates in clips to connect to the battery's post. The other end terminates in a white connector to plug into a CH150, CH200, CH201, CH100, PS150, PS200, or PS100. The 34031 may be purchased to replace a lost or damaged cable, or it may be purchased by those supplying their own batteries locally.

Compatibility
Enclosure Considerations
A desiccated, non-condensing environment is required. The CH150 includes built-in keyhole flanges for mounting to the backplate of a Campbell Scientific enclosure.
Adapters
The CH150 is compatible with the A100 null-modem adapter and the A105 adapter for additional 12 V output terminals. The A100 Null Modem Adapter connects and powers two Campbell Scientific peripherals via two CS I/O 9-pin connectors configured as a null modem. This is useful in linking different communications technologies, such as telephone to radio, at sites that do not have a data logger. The A105 adapter may be used to provide additional 12 V and ground terminals where the power supply is used to power several devices.
