Kyocera LYNCOM SR7 User manual

Specifications subject to change without notice.
Models SR7 and SR7C are advanced products
designed for use in small size solar electric
systems, typicallyused forrecreationalvehicles,
wireless-local-loop applications, small rural
electrification and introductory level PV
systems. The controllers solid state design
providesa 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.
