Kyocera SR7, SR7C DATASHEET

LYNCOM MODELS SR7 AND SR7C BAT T E RY AND LOAD C O N T R O L L E R S

Models SR7 and SR7C are advanced pro d u c t s designed for use in small size solar electric systems, typically used for re c reational vehicles, w i reless-local-loop applications, small rural electrification and intro d u c t o ry level PV systems. The controllers solid state design p rovides a cost-effective migration of technology for users and systems curre n t l y using relay based or traditional “on/off” c o n t rollers. The SR series features a pulse-width-modulation circuit, which positively ensures a well-controlled bulk and then taper charge of the battery at the regulated voltage. This unique design without the micro p rocessor finally brings to the first-time user a PWM product at a price, which is extremely attractive. The SR7C is a charge-only model and SR7 is supplied with a LVD as standard. Controller status is displayed on three LEDs.
