Multi-channel Power Controller

G3ZA

Multi-channel Power Controller

G3ZA

Optimum Cycle Control for High-precision Control
with Low Noise

• Smaller than a Normal Power Controller.

• Enables low-noise power control in combination with zero-cross SSRs.

(See note.)

• One Controller can control up to 8 SSRs.

• RS-485 communications to set manipulated variables and heater

burnout detection. The Smart FB Library for the G3ZA can also be used.

• CE Marking

Main Upgraded Functions

• Soft-start function added for lamp heaters.

• Three-phase optimum cycle control added for three-phase heaters.

• Combining with special CT for150-A current detection.

Note:

The G3ZA must be used in combination with an SSR without the zero cross
function when the soft-start function is used.

Version Upgrade for Improved Functionality (V2)

Connec-
tions

Power Controllers Controlled Using Current Output of 4 to 20 mA

Control Using Communications from a Host Device

•

Direct connection is possible using an EJ1 Modular Temperature Controller.

Control
method

Phase Control
•

Response is fast and high-precision temperature control is possible.

•

Harmonics and noise are problems.

Optimum Cycle Control (High-precision Zero Cross Control)
•

Outputs are turned ON and OFF each half cycle.

•

Zero-cross control is performed.

•

Noise is suppressed while achieving high-speed response with high-
precision temperature control.
