The JU collection small and light-weight thyristor regulators for single-phase hundreds are characterised with excessive panel set up density. Two manage systems, a phase-angle firing gadget and a zero-cross firing system, are constructed in and can be modified through far off contacts signal.

Features
– Compact structure
– Compact, light-weight and excessive panel set up density
– Options
– The alternatives of heater disconnection alarm feature and contemporary restriction feature are available.
– Phase-angle firing/zero-cross firing
– The phase-angle firing device and the zero-cross firing machine are selectable. The walking by way of the phase-angle firing device at the preliminary stage and by means of the zero-cross firing gadget at the ordinary stage is possible.
– Zero-cross firing system
– With the delta-sigma modulation, which controls each 1 cycle, the fantastic manage like the phase-angle firing device is possible.
– Setting unit (option)
– Display of quite a number parameters, voltage/current/ energy and exchange of the remarks gadget are possible.
– Various protections features built-in
– The thyristor component is included by way of melting of the fast fuse for short-circuit of load, and by means of gate-off for over-current. For fashions with a cooling fan built-in, alarm is activated and output is stopped for atypical heat-sink temperature.
– Self-diagnosis characteristic built-in
– The self-diagnosis feature is constructed in for odd operation, strange thyristor thing and ordinary energy supply.
