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 user­supplied 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.

NOTE

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.

WARNING

An internal or external battery is connected to the charger by means of the INT
(Internal) or EXT (External) connectors, as shown in Figure 1. An “external
battery” cable is available for the charger. This cable connects another battery
with the charger to provide power if the main battery is removed. The red lead
connects to the positive battery terminal and the black lead connects to the
negative terminal.

Reversal of polarity of external battery will damage the
PS100 or CH100.

PS100 and CH100 Power Supply and Charging Regulators

It is possible to leave two batteries connected. The battery connections are
diode isolated (Figure 2); however, if one of the batteries fail, it could draw all
the charging current and the other battery will be discharged.

CAUTION

From Transformer

or Solar Panel

To Datalogger
or Peripherals

A battery must be attached for the charger to function
correctly as a power supply.

The leads from the transformer or solar panel are connected to the CHG
terminals. Polarity does not matter; either lead can be connected to either
terminal.

The wires that connect power to the datalogger and/or peripherals are
connected to the +12 and ground (

To Battery

) terminals.

4. A100 Null Modem Adapter

The A100 has two 9-pin CS I/O ports with a null modem between them. The
ports are used to connect two 9-pin devices that would normally be connected
to the CS I/O port on a Campbell datalogger. The charger supplies 12 volts
and 5 volts to the appropriate pins on the connector for powering the connected
devices.

CAUTION

This cannot be used as a null modem between two RS­232 devices.

5. A105 12V Terminal Expansion Adapter

The A105 adapter adds four 12-V terminals and four ground terminals to a
CH100 or PS100 (see Figure 4). The extra terminals make it easier to wire
multiple continuously powered 12-Vdc devices to the power supply.
