The CS110 requires 11 V to 16 Vdc with a peak current demand of 750 mA
during motor operation. The CS110 Power Cable (pn 16965) is used to
connect the dc power supply to the CS110. The recommended maximum
length on the CS110 Power Cable (CS110CBL3-L) is 50 feet. The CS110 is
protected against accidental reversal of the positive and ground leads from the
dc power supply. Transient protection is also included on the power supply
inputs. DC input voltages in excess of 18 V may damage the CS110.
4.2 Campbell Scientific, Inc. Power Supplies
The PS100 provides a 12 Vdc, 7.0 Ahr rechargeable power supply for the
CS110 and peripherals. The CH100 is a charging regulator for 12 V
rechargeable batteries that is commonly used with the larger 12 amp hour
(BP12) and 24 amp hour (BP24) Battery Packs. The rechargeable battery can
be trickle-charged from an ac power wall charger. The PN: 9591 wall charger
accepts 110 Vac while the PN: 14014 accepts 90 to 264 Vac. Charging power
can also come from a 17 – 28 VDC input such as a solar panel. Depending on
power requirements, 10 watt or 20 watt solar panels (SP10 or SP20) are
available.
4.3 Communication Options
The circular RS-232 connector on the underside of the CS110 can be used to
interface directly to RS-232 devices (DB-9), utilizing the CS110 RS-232 cable
(CS110CBL1-L).
The circular CS I/O connector on the underside of the CS110 can be used to
interface directly to various Campbell Scientific, Inc. peripherals, utilizing the
