AUCTION PRICE IS FOR ONE BRAND NEW INDUSTRIAL Solar charger CONTROLLER. The Phocos CIS-20 is an industrial-grade solar charge controller that is suitable for all practical PV applications. It conforms to the IP68 protection system. Four-stage PWM-charging is combined with low-voltage disconnect, flexible load timer functions, and a multi-LED system status display. The CIS-20 comes with a charge output and a control output for dimmable ballasted lamps. The CIS-20 has no moving parts, switches, or buttons. 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. Features One output as on-off switch and another as output with dimmer function (optional) Corrosion-proof epoxy-encapsulated PCB (IP68) Compact size Infrared remote control programming accessory (CIS-CU additional item) Intelligent timer functions available for lighting control Four-stage battery charging (main, float, boost, equalization), temperature compensated Automatic system voltage recognition (12/24 V) Auto-saving function: two voltage disconnect levels Specifications: Model No.: CIS-20 Nominal Voltage: 12/24V Max Charging / Load Current: 20A Charging technology: PWM Supported Battery Type: Lead-acid ( Gel, AGM, Flooded) Dimensions (W x H x D): 82 x 61 x 20 mm Weight: 150 g Suitable Applications Stand-alone solar systems Small home systems Solar lighting systems Solar Telecommunication Marine use on boats and yachts
