LYNCOM MODELS SR7 AND
SR7C BATTERY AND LOAD
CONTROLLERS
Models SR7 and SR7C are advanced products designed for use in small size solar electric systems, typically used for recreational vehicles, wireless-local-loop applications, small rural electrification and introductory level PV systems. The controllers solid state design provides a cost-effective migration of technology for users and systems currently using relay based or traditional “on/off” controllers. 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 microprocessor 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.
