The flagship version of the Leister LHS line is the LHS System. Like the LHS Premium, the System version is easy to integrate, has overheat protection with alarm output for the element and the tool and has infinitely adjustable heating capacity via it’s onboard potentiometer. The LHS System tool can also be remotely controlled via analog interface (4-20mA or 0-10V). With the exception of the LHS 91, the System version tools have built in temperature probes and controllers with LED display showing target/actual value display. The on-board power electronics simplify the wiring and make external power control optional.
