The SHP thyristor controller from Systemtechnik Leber meets the demand of numerous system and machine manufacturers for more space in the control cabinet. The design of the thyristor controller has been reduced to a width of 22.5 mm. The standard version of the device has an output of up to 30 A and offers functions such as digital and analog interfaces, phase control, burst control, zero-point switching, soft start and a cost-neutral option for networking using a serial protocol. The thyristor controller is also equipped with various monitoring functions, including mains monitoring, load monitoring and the detection of total errors. Any faults that occur are indicated visually by LEDs, but can also be evaluated via the interface. The user has a free choice of the required control, regulation and evaluation functions.
