Technical Parameters
The specifications are divided into two parts: the main unit (UP750-51/Z) and the current transformer (Z25).

1. Main Unit: Yokogawa UP750-51/Z (Programmable Indicator)
Category Parameter Specification
Input Signal Type (Pre-configured) AC Current, via Current Transformer (CT).
Standard Input Typically 0-5 A AC (from the secondary side of the CT).
Display Type Large, high-brightness LED or LCD display.
Digits 4 or 5 digits (e.g., 0.00 to 9999).
Power Supply Rated Voltage 100-240 VAC, 50/60 Hz (or 24 VDC, depending on order code).
General Performance Accuracy ±0.3% of reading ±1 digit (typical for AC signals).
Sampling Cycle Approx. 0.5 seconds.
Isolation Between Input, Power Supply, and Output.
Mounting Style Panel-mounted (cut-out required).
2. Sensor: Yokogawa Z25 (Split-Core Current Transformer)
Category Parameter Specification
Type Style Split-core (clip-on type).
Rated Primary Current Range 50 A (This is a common rating for the Z25. The UP750 display will be scaled to match this. Please verify the exact rating for your specific model).
Rated Secondary Current Output 5 A (standard CT output).
Frequency Range 50/60 Hz.
Accuracy Class Class Typically Class 1.0 or better.
Core Diameter Size Designed to fit around a conductor of a specific size (e.g., up to 25mm diameter).
