Omron G3PW Manual

New Product
Single-phase Power Controller
G3PW
High-precision Control with Easy Setup
• Precise heater burnout detection.
• Set value and present value monitoring with indicators.
• Phase control or optimum cycle control.
• RS-485 communications to set manipulated variables and
monitor load current.
• Total run time monitoring.
• Output modes for phase control: proportional to phase angle
(same as G3PX), proportional to voltage, proportional to
square voltage, and constant-current control.
• Application with various loads: constant load resistance,
variable load resistance.
• Certified for CE and pending for UL.
