Product Description

• Can be ordered with one output as on-off switch and
another as output with dimmer function (CIS) or two
on-off switches (CIS*2L)
• Corrosion-proof epoxy-encapsulated PCB (IP*8)
• Compact size
• Infrared remote control programming accessory (CIS-CU)
• Intelligent timer functions available for lighting control
• Four-stage battery charging (main, float, boost, equalization),
temperature compensated
• Automatic system voltage recognition (*2/*4 V)
Isolated PV systems exposed to extreme weather/environmental
conditions (streetlights, navigation buoys, etc.) have
increased risk for damage to the power electronics. In order
to assure reliable battery protection under such conditions,
Phocos developed a fully encapsulated charge controller to
prevent corrosion: CIS.
CIS is an industrial-grade charge controller that is suitable
for all practical PV applications. It conforms to the IP*8
protection system. Four-stage PWM-charging is combined
with low-voltage disconnect, flexible load timer functions,
and a multi-LED system status display. CIS is available in two
versions:
SingleLoad version with dimming output (CIS): The CIS
comes with a charge output and a control output for dimmable
ballasted lamps.
DualLoad version with two load outputs (CIS*2L):
The CIS*2L comes with two charge outputs to independently
control two loads.
The CIS has no moving parts, switches, or s. Settings
such as battery type, deep discharge thresholds, timers, and
other configuration items are made quick and easy by
infrared remote control.
