Jednofázové tyristorové regulátory řady JU

JU series single-phase thyristor regulators

JU is a series of small and lightweight single-phase power regulators. Two control systems (phase and group) are built into the unit. The type of control is selected by means of appropriate terminals. Power control is by 4..20 mA, 1..5 V signal, potentiometer or ON-OFF type. For phase control, the controller can optionally be equipped with voltage, current or power feedback functions depending on the type of load.

Features:

  • compact construcion
  • phase control / group control
  • automatic frequency detection 50 Hz/60 Hz
  • optional operator panel - displays information about current, voltage, power, possibility to change the type of feedback
  • protection – fast fuses
  • signaling incorrect system operation
