ESGT 3PH

General parameters of three-phase power regulators of the ESGT series:

  • Load supply voltage: 400 VAC (optional: 110, 500, 690, 1000 VAC), 50 Hz
  • Regulator supply voltage: 230 VAC, 50 Hz (optional: 400 VAC or 24 VDC)
  • Degree of protection against dust and moisture: IP 23
  • Control signals: 0...10 V, 0...20 mA, potentiometer, (optional 4...20 mA)
  • Phase switching for inductive (transformer) load
  • Batch switching for active (resistive) load
  • Regulators provide optical and electrical fault indication:
    • phase loss
    • exposure of temperature
    • reduced voltage
    • Thyristor Defect
  • Controller working temperature 0...+55°C
  • Permissible humidity not lower than class E according to DIN 40040
  • Compliance with the German standards VDE 0558 (part 1) and VDE 0160
  • Compliance with European standards CE, EN 60204, IEC 947-4-2
  • Optional options available (optional):
    • Constant current maintenance in the load, set by potentiometer (only possible with phase switching), (I)
    • Constant voltage at load, set by potentiometer (only possible with phase switching), (U)
    • Current limitation in load 5...100%, set by potentiometer (only possible with phase switching), (IB)
    • Analog output proportional to the current in the load (only possible with phase switching), (AI)
    • Analog output proportional to the voltage at load (only possible with phase switching), (AU)
    • Auxiliary own power supply of the regulator from an external 24 V DC source, (24VDC)
    • Auxiliary own controller power supply from external 400 VAC, (400V)
    • Auxiliary own supply to the regulator is generated from the mains voltage, (IV)
    • Power management in load by external current signal 4...20 mA, (4...20mA)
    • Electronic switch-off of the regulator when maximum current is reached, (ES)
    • Double option. Electronic switch-off when maximum current is reached and current limitation, (only possible with phase switching), (ES/IB)
    • Interface RS485 Modbus, (Mod)
    • Improved degree of protection against dust and moisture IP55, regulator in protective housing, (IP55)
    • Maximum regulator operating voltage 690 V, (U690)
    • Maximum regulator operating voltage 1000 V, (U1000)

Thyristor regulators with IP20 protection must be installed in a forced ventilation control cabinet, which ensures efficient removal of generated heat and maintenance of the regulator temperature not exceeding +55°C. Measures must be taken to prevent dust and dirt from entering the regulator. Excessive humidity, aggressive atmosphere, vibration and other mechanical influences must also be avoided.

The ESGT regulator is connected to the network via a circuit breaker and fuses, which can be installed either directly on the regulator busbars or separately in the enclosure. The tripping current of the recommended fuse is specified in the enclosed documentation. With each order we will also offer optional fast fuses of the Ultra-Rapid series manufactured by the German company SIBA. It is possible to order fuses in any quantity, either as a regulator package or in spare parts.

Mains chokes and filters are recommended in order to maintain the quality of the mains voltage and prevent high frequency interference. If necessary, our company will offer suitable models in each case.
