Section 4 Isco Battery Chargers and Power Packs
4.1 Isco Chargers and
Power Packs
Teledyne Isco offers several battery chargers and two different
power packs for use with all Isco products. You can use the power
packs instead of the nickel-cadmium or lead-acid batteries to
power the samplers, flow meters, or other equipment.
The power packs are made for operation from either nominal 120
VAC, 60 Hz (USA) or 220-240 VAC, 50 Hz (Europe and much of
the rest of the world) power sources. The 120-volt models are
supplied with the three-prong cord commonly used in the USA
and Canada. The 220-240-volt models are supplied with the most
common two-prong plug used in Europe.
4.2 Model 961 Battery
Charger
The simplest charger is a wall plug-in transformer type, Model
961, intended for charging the Model 934 Nickel-Cadmium
Battery. This charger provides the proper charging current
(400 mA) for the nickel-cadmium battery. Only one version,
powered from 120 VAC, is available.
