PS100 and CH100 Power Supply and
Charging Regulators, A100 Null Modem
Adapter, and A105 Additional 12 V
Terminals Adapter
1. General Description
The PS100 is a 12-volt power supply that includes a charging regulator and a
7 amp hour battery. The CH100 is a charging regulator that is used with a
Campbell Scientific battery pack such as the BP12 or BP24 or with a user-
supplied battery. Charging power is typically supplied by an AC transformer
or an unregulated solar panel.
The PS100 and CH100 each have one adapter connector that will allow
connecting one of the following adapters.
The A100 Null Modem Adapter has two 9-pin connectors that provide a null
modem for use in a site, without a datalogger. The A100 connects and powers
two Campbell Scientific peripherals that would normally be connected to a
datalogger. These peripherals are typically modems linking different
communications technologies; e.g., telephone to radio.
The A105 Additional 12 V Terminals Adapter may be used to provide
additional 12 V and ground terminals where the power supply is used to power
several devices.
To prevent people from getting burned, an ABS plastic cover
[CSI #18688] sits on the heatsink of a PS100 or CH100. The
cover is fastened to the heatsink via a #4-40 x .250 Pan Phillips
screw [#395]. The cover must be removed to attach an A100 or
A105 adapter. Some early models of the PS100 and CH100 did
not include the cover and do not have a place to attach it. NOTE
