G3PW

Features

Thyristor-type single-phase power controller that enables precise temperature control

Compact and the possibility for side-by-side mounting for multiple units are the basics for this new generation of power controllers. Proces value can be easily monitored via the 7-segment display on the front panel.

  • Precise heater burnout detection
  • Phase control or optimum cycle control
  • RS-485 communications to set manipulated variables and monitor load current
  • Total runtime monitoring
  • Application with various loads: constant load resistance, variable load resistance

Control method

Analog input: Phase control or optimum cycle control

Voltage ON/OFF input: ON/OFF control

Maximum load capacity

Phase control: Linear (resistive) load, transformer primary-side control (flux density: 1.25 T max.)

Optimum cycle control: Linear (resistive) load (Transformer primaryside control is not supported.)

Output mode

Analog input

Phase control

Proportional to phase angle (same as G3PX), proportional to square voltage, proportional to voltage

Proportional to phase angle (same as G3PX), proportional to square voltage, proportional to voltage, constant-current control

Optimum cycle control

Optimum cycle control (Output is switched to 100% or 0% each half cycle.)

Voltage ON/OFF input

ON/OFF control

Proportional to voltage control
